Settings in 0.9.9

These are the settings on the Configure page of version 0.9.9, in the order the app shows them. Settings marked Advanced are hidden while the page is set to Basic.

Other versions

Identity

Panel ID

Basic · panel_id

Stable id used in entity IDs and MQTT topics (lowercase, digits, underscores; 63 characters maximum).

Friendly name

Basic · friendly_name

HA device display name.

This is the name shown:

• on the panel’s device card in Home Assistant, whether the panel is connected through Panel Assistant or through MQTT;
• for this panel in other panels’ header switcher.

Left blank, it uses the Android device name, which is also what the Home Assistant Companion app uses by default, and falls back to the model when the device has no name. Unlike Panel ID it is only a label, so you can rename it at any time without affecting entity IDs. It is never copied when settings are applied to another panel.

Manufacturer

Advanced · manufacturer

HA device-card manufacturer override (blank = profile/auto).

Model

Advanced · model

HA device-card model override (blank = profile/auto).

Area in Home Assistant

Basic · ha_area

Where this panel lives, by Home Assistant area name. This can only be changed in ha-paneld if your HA user has admin permissions, otherwise change it on your device in HA.

MQTT

Broker URL

Advanced · mqtt_broker

Blank auto-discovers HA over mDNS.

Note

MQTT is the older way a panel’s screen, buttons and sensors reach Home Assistant. Panels can now move those entities to Panel Assistant, which needs no broker, and MQTT support is due to be removed before version 1.0.

Left blank, the panel looks for Home Assistant on the local network over mDNS and connects to tcp://<address>:1883 on the Home Assistant instance that has that port open, which suits the Mosquitto add-on. Enter a URL when your broker runs elsewhere or on another port.

Scheme	Connection	Port when none is given
tcp://, mqtt://, or no scheme	unencrypted	1883
ssl://, mqtts://, tls://	TLS	8883

Examples: homeassistant.local, mqtts://192.168.x.x, tcp://[fd00::10]:1883 (IPv6 addresses go in square brackets).

WebSocket brokers, paths and user names inside the URL are not accepted; put credentials in Username and Password. How the host name is resolved is set by address family.

Related: Move a panel from MQTT

Username

Advanced · mqtt_user

Credential for this panel.

The user name the panel gives the broker, together with Password. With the Mosquitto add-on this is usually a Home Assistant user you created for the panel.

• Clearing the user name also clears the stored password, so the panel connects without credentials.
• If the broker rejects the pair, the panel status shows that authentication was rejected.

The value is treated as specific to this panel and is not copied to other panels by default.

Related: Move a panel from MQTT

Password

Advanced · mqtt_password

Blank on save keeps the current password.

The password for Username. The form never shows the stored password, so the field is empty each time you open it.

When you save with	The stored password
the field empty	is kept
a new password	is replaced
the user name cleared	is cleared as well
a changed broker URL and the field empty, in Hardened security mode	is discarded

Like the user name, it is not copied to other panels by default.

Related: Move a panel from MQTT

MQTT + Home Assistant WebSocket address family

Advanced · mqtt_address_family

Applies to the MQTT broker connection and the panel's Home Assistant WebSocket connections; plain HTTPS reads always try every published address. Automatic learns a working route and falls back between IPv6 and IPv4. Prefer IPv4 keeps IPv6 as a fallback; Force IPv4 rejects endpoints with no IPv4 address.

Behaviour

Auto-sleep activity source

Basic · auto_sleep_source

Use the panel’s calibrated proximity sensor, Home Assistant Area devices, or touch inactivity.

• Presence modes pause if their source is unavailable.
• Touch inactivity needs no presence setup.

Touch inactivity delay (seconds)

Basic · Default 30 · 5 to 86 · auto_sleep_touch_delay_seconds

When Touch inactivity is selected, switch the screen fully off after this many seconds without a touch.

Auto sleep

Basic · Default off · Home Assistant switch · auto_sleep

Switch the screen off after the selected presence mode’s learned delay or the chosen touch inactivity delay. Manual screen control remains separate.

Navbar mode

Basic · Home Assistant select · navbar_mode

Soft on-screen navigation bar for panels with no native navbar. **Native** leaves navigation to the panel's own Android bar and draws nothing.

Hiding the Android system bars, from the built-in renderer’s fullscreen setting or the Android dashboard lock, still hides a native bar.

Wake on wave

Basic · Default off · Home Assistant switch · wake_on_wave

Wake after a calibrated clear-to-near-to-clear wave. Set up proximity on the panel; touch-to-wake remains available.

Lock Android to dashboard (experimental)

Advanced · Default off · Home Assistant switch · kiosk_lock

Root-only casual-use lock. Hides Android system bars and returns to the selected dashboard within about 3 seconds when another app or Recents opens. It does not hide Home Assistant navigation.

Release it:

• here, or from Home Assistant
• through adb
• with 7 rapid top-left taps
• during the 60-second unlocked window after reboot

App watchdog

Advanced · Default off · watchdog_enabled

Self-heal the dashboard app: relaunch if it dies, return if backgrounded too long.

When the watchdog is on, Panel Assistant checks the dashboard app every 30 seconds and acts on two situations. It never acts while the dashboard is in front.

Situation	What the watchdog does
The app’s process is dead on two checks in a row	Starts the app again
The app is running but has not been in front for five minutes, for example because someone opened Settings and walked away	Brings the dashboard back to the front
The app keeps crashing as soon as it starts	Backs off instead of relaunching over and over, and shows a health warning; this clears when the dashboard comes back to the front

Someone leaves the dashboard at 0. The watchdog leaves them alone until the app has been in the background for five minutes.

The watchdog needs root or the Panel Assistant helper to see the dashboard’s state, and does nothing on panels with neither.

Tip

Leave it off if you often use other apps on the panel for longer than five minutes. For a faster return that also hides the Android bars, use Lock Android to dashboard instead.

Apps the lock allows

Advanced · kiosk_companion_packages

Android package names, separated by commas, that the dashboard lock leaves in front instead of returning to the dashboard. Use it to reach a companion app's own screens. Needs root.

Touch sound

Basic · Default on · Home Assistant switch · touch_sound

Audible tap feedback (system touch sounds).

The dashboard runs in a web view, which does not play Android’s touch sounds, so Panel Assistant plays its own short click when the screen is tapped, and also turns Android’s system touch sounds on or off for the panel’s native screens. The click plays at the panel’s media volume, so it follows that volume rather than the ringer or notification volume.

The setting changes immediately and is also a switch on the panel’s device in Home Assistant, which makes it easy to silence taps at night from an automation. It does not affect the on-screen keyboard’s own key sounds.

Silence boot chime

Basic · silence_boot_chime

Mute the firmware startup chime.

Some panel firmware plays a chime at startup through the ring and notification volumes. Turning this on records those volumes, then silences them, so the panel restarts quietly. It is on by default. Turning it off restores exactly the volumes recorded when it was turned on. If there is no recorded volume, for example after upgrading from an older version that did not record one, the panel stays silent rather than guessing a level.

Because the chime and ring or notification sounds share the same volume on these panels, leave this on unless you need those sounds from the panel.

Prevent idle dim

Basic · Default on · prevent_idle_dim

Stop the vendor firmware dimming the backlight at the screen-off timeout.

Some panel firmware turns the backlight right down when Android’s screen-off timeout passes, even while the screen is meant to stay on, so the panel goes very dim some time after the last touch.

State	What Panel Assistant does
On (default)	Saves the current screen-off timeout once and sets it to never; the built-in renderer also keeps the screen on while it is showing
Off	Puts back the saved timeout, or 60 seconds if none was saved

It should normally stay on for a mains-powered panel. Screen sleep that you want is better handled by Auto sleep.

Note

In Hardened security mode, turning it off from the network needs approval at the panel.

Related: Security mode

Keep panel responsive

Advanced · Default on · keep_awake

Keep the network and background services running while the screen is off.

With this on, Panel Assistant holds two Android locks:

• one that stops the processor from going into deep sleep;
• one that stops the Wi-Fi radio from going into power saving.

Without them, a panel with its screen off can stop answering on the network, drop its connection to Home Assistant or miss commands. The screen can still turn off as normal.

It is on by default because wall panels run on mains power. Turn it off only on a battery-powered device where standby time matters more than staying reachable.

Note

In Hardened security mode, turning it off from the network needs approval at the panel.

Related: Security mode

Display

Dark mode

Basic · Default on · dark_mode

Themes ha-paneld's own screens and sets the dashboard's default colour scheme on panels without a system dark-mode setting (Android 9 and older).

A theme picked inside Home Assistant overrides the dashboard default; this web UI always follows the viewing browser’s own preference.

Ambient light source

Advanced · auto_brightness_ha_entity

Blank uses the panel light sensor. Select a Home Assistant illuminance sensor when the panel has no suitable sensor.

Show network warning on dashboard

Advanced · Default on · dashboard_network_warning

Show the network connection warning on this panel's dashboard. Network checks and status remain available when this is off.

Auto-brightness

Basic · Default off · Home Assistant switch · auto_brightness

On-panel engine maps a lux stream to the backlight (off = HA drives the screen).

Minimum level

Advanced · auto_brightness_minimum_percent

Lowest automatic screen level as a percentage. Proposals scale between the minimum and maximum; manual brightness can still go lower.

Maximum level

Advanced · Default 100 · auto_brightness_maximum_percent

Highest automatic screen level as a percentage. Proposals scale between the minimum and maximum; manual brightness can still go higher.

Sensitivity

Advanced · Default 50 · 0 to 100 · auto_brightness_response_percent

How much of the difference from the learned ambient-light pattern is applied to the screen, once the engine has decided a change is real.

• Lower values keep the screen closer to its learned daily pattern.
• While the pattern is still being learned the screen follows the measured light directly.

System

CPU profile

Advanced · Home Assistant select · cpu_governor

Live CPU scaling profile until reboot; Auto = the SoC's dynamic governor.

Zigbee router

Advanced · Default off · zigbee_router

Run the on-board Zigbee gateway as a router/repeater (NSPanel Pro).

This setting appears only on a panel with a built-in Zigbee gateway, such as the Sonoff NSPanel Pro. Turning it on starts the vendor gateway if it is not already running and switches it to the Repeater role, so the panel can extend an existing Zigbee network run by your own coordinator. To join it to that network:

1. Turn this switch on and save.
2. Open permit-join on your coordinator.
3. Use Request join in the Join Zigbee network row that appears under the switch. The button stays disabled once the router has joined.

Turning it off stops the gateway and frees the radio. Stock firmware often starts the gateway at boot by itself, and Panel Assistant only stops it when you have set this switch explicitly, so a gateway you already rely on is left alone by default.

Caution

On some stock firmware the vendor gateway cannot be stopped from the app and keeps running until the next restart.

While the router is on, Panel Assistant samples the gateway once a minute. After a 15-minute start-up grace period it treats the gateway as a runaway if either of these happens:

• it restarts three or more times within ten minutes;
• it stays unjoined while using more than half a CPU core for five consecutive samples.

A runaway gateway is stopped and this setting is turned off, to protect the panel’s responsiveness.

Samples during the grace period never count; only after minute 15 can five high readings in a row contain the gateway.

Interface language

Basic · ui_language

Language used by ha-paneld's own interface.

Automatic uses an explicit page override first. Configure setting labels and help can then follow the connected Home Assistant user’s language; browser, device and English are the remaining fallbacks.

Launcher app

Advanced · launcher_package

App the Launcher button brings forward. Blank auto-picks an app. Selecting Panel admin (ha-paneld) also makes and keeps ha-paneld the Android Home app.

Network ADB

Advanced · Default off · Home Assistant switch · network_adb

**Security risk:** keeps classic ADB listening on TCP port 5555 across boots and reconnects.

Enable only during active maintenance on a trusted network. If ADB was enabled outside ha-paneld, it must also be disabled there.

Camera

Camera

Basic · Default off · camera_enabled

Off by default. Serves RTSP video with room audio where a microphone is available and permitted, and JPEG snapshots for Home Assistant. Capture starts only when a client requests media, and the panel shows a red light while the camera is open.

Resolution

Basic · camera_resolution

What a stream gets when its URL does not ask for something else. A stream URL can override it with ?res=, in either direction.

Frame rate

Advanced · Default 15 · 1 to 30 · camera_fps

What a stream gets when its URL does not ask for something else. A stream URL can override it with ?fps=, in either direction.

Bitrate (kbps)

Advanced · Default 2000 · 250 to 8000 · camera_kbps

What a stream gets when its URL does not ask for something else. A stream URL can override it with ?kbps=, in either direction.

Exposure

Advanced · Default 0 · -2 to 2 · camera_exposure

Exposure bias in stops, for a camera that reads a room darker or brighter than it looks. 0 leaves the camera's own automatic exposure alone; the panel clamps this to whatever range the sensor actually supports.

Dashboard

Dashboard app

Advanced · dashboard_package

App used for the dashboard. Blank uses ha-paneld's built-in renderer.

This chooses which app draws the dashboard on the panel. The list always starts with Auto and Built-in renderer, followed by any supported Home Assistant Companion app installed on the panel. Using the Companion app as the dashboard is retired: it is listed only so a panel already set up that way keeps working, and Panel Assistant never removes it for you. Other launchable apps are not offered. If the panel is already set to an app the list does not recognise, that choice stays in the list rather than being dropped silently.

Choice	Stored value	What happens	When to pick it
Auto	blank	Uses Panel Assistant’s own renderer.	The usual choice.
Built-in renderer	builtin	Uses Panel Assistant’s own renderer, named explicitly.	When you want the choice spelled out in a backup or script.
A Companion app	its Android package name	Hands the dashboard to that app.	Retired as a panel dashboard. A panel already using it keeps working; switch to Auto once the panel is in Panel Assistant.

A change takes effect immediately: the panel launches the newly selected app as soon as the setting is saved. Selecting the built-in renderer needs a working Home Assistant connection first, so connect with Browser sign-in before choosing it.

Note

Most settings on this card apply only to the built-in renderer, including Home dashboard idle return, Dashboard theme, Entity filtering and Zoom (%). Saving an idle return time while a Companion app is selected is refused.

Related: The built-in renderer

Entity filtering

Basic · Default off · dashboard_entity_learning

Built-in renderer: limit Home Assistant's state stream to dashboard-used entities and learn runtime dependencies. Manage sources and pins in Entities.

Home dashboard

Basic · home_dashboard

Dashboard used by reload and idle return.

• Auto lets Home Assistant choose.
• Custom accepts a specific view, e.g. /dashboard-name/tab-name.

Dashboard theme

Basic · dashboard_theme

Built-in renderer only.

• Follow Home Assistant leaves the dashboard’s light/dark choice to Home Assistant, which is what the Dark mode setting supplies a default for.
• Dark and Light choose it on this panel when Home Assistant is set to Auto, for a kiosk dashboard with no sidebar to reach the Home Assistant profile page from.
• Ambient chooses Dark or Light from the room’s light as the auto-brightness model sees it, and changes only after the room has stayed darker or lighter for a minute; it needs Auto-brightness on, and follows Home Assistant until it has a reading.

An explicit Light or Dark choice in Home Assistant still wins; use Auto or a separate panel user. Returning to Follow Home Assistant hands the choice back exactly as it was found.

Hide Android system bars

Advanced · Default on · dashboard_fullscreen

Built-in renderer only. Hides Android's status and navigation bars while the dashboard is in front; swipe from an edge to reveal them temporarily.

It does not lock the panel or hide Home Assistant navigation.

Hide Home Assistant navigation (native)

Advanced · Default on · dashboard_native_kiosk

Built-in renderer only. After Home Assistant 2026.4.2+ connects, asks its native frontend to hide its navigation.

On by default; an unsupported or failed request leaves the dashboard unchanged. It does not lock Android or inject CSS into the dashboard.

Idle return to home (min)

Basic · Default 0 · 0 to 1440 · dashboard_idle_return_min

Built-in renderer: return to Home dashboard after this many idle minutes. 0 = off.

Idle means nobody has touched the screen. The panel checks once a minute, so the return happens up to a minute after the time you set. It returns only when all of these hold:

• the screen is on;
• the dashboard is connected to Home Assistant;
• the dashboard is not already showing the home view.

The return swaps the view in place, without reloading the page.

With a 5 minute setting, the return happens at the first check after five minutes without a touch.

The destination is Home dashboard, including a specific tab if you set one. With Home dashboard on Auto, the panel waits until Home Assistant has told it which dashboard is the account’s default.

Value	Effect
0 (default)	Off. The panel stays wherever it was left.
1 to 1440	Returns home after that many idle minutes; 1440 is one day. A value such as 5 suits a shared panel where people wander into other views.

Note

This works only with the built-in renderer. Saving a value while a Companion app is selected in Dashboard app is refused.

Related: The built-in renderer

Home Assistant URL

Basic · ha_url

Built-in renderer: Home Assistant base URL, e.g. http://homeassistant.local:8123. Blank disables it.

Long-lived access token

Advanced · ha_token

Use browser sign-in when possible. This fallback can be created in your Home Assistant user profile.

Zoom (%)

Advanced · Default 100 · 50 to 300 · dashboard_zoom

Browser zoom.

Voice

Voice assistant

Basic · Default off · voice_enabled

Run the on-panel wake-word listener and send recognised speech to Home Assistant Assist.

Wake words

Basic · voice_wake_words

The wake words to listen for: the bundled Okay Nabu, Hey Jarvis, Hey Mycroft and Alexa, and any you import below.

Wake word pipelines

Advanced · voice_pipelines

Which Home Assistant Assist pipeline each wake word runs. A wake word left on the preferred pipeline follows whichever pipeline Home Assistant prefers.

Audio source

Advanced · voice_audio_source

Android audio source the wake-word listener records from.

Wake sensitivity

Advanced · voice_sensitivity

Wake-word detector threshold, applied as an offset to the model's cutoff score.

• Low requires a clearer match: fewer false wakes, more likely to miss a quiet or distant call.
• Normal applies no offset.
• High matches more readily: faster to wake, more false triggers.

Microphone gain (dB)

Advanced · Default 0 · voice_mic_gain_db

Amplifies the audio sent to Home Assistant for transcription.

These panels expose no platform noise suppression or automatic gain control, so a panel heard from across the room may wake reliably and still transcribe poorly: wake-word detection adapts to a quiet signal on its own and speech-to-text does not.

Raise this if commands are missed or mistranscribed while the wake word works. Wake-word detection is deliberately left on the unamplified signal.

Logging

Ship logs

Advanced · Default off · log_ship_enabled

Forward ha-paneld's own process log — not the full system log — to a central sink (LAN-only, tokens and passwords redacted).

Ship system logs

Advanced · Default off · log_ship_system_enabled

Forward Android system logs to the same sink when Ship logs is on.

• Off by default.
• Requires TCP or HTTP, and root or the installed helper.
• Entries are redacted; high-volume output may be dropped.

Sink host

Advanced · log_ship_host

Log-collector host; blank keeps shipping inert. A scheme or :port here is honoured (udp://collector, collector:1514).

Sink port

Advanced · Default 514 · 1 to 65535 · log_ship_port

Protocol

Advanced · log_ship_protocol

TCP is the default because it reports a sink that is refusing or unreachable; UDP cannot, so a wrong setting there fails silently. Port 514 serves both.

Sensors

Screen brightness

Basic · Home Assistant light · screen

Current screen state and brightness. Home Assistant presents the light's native 0–255 brightness as a percentage.

Panel volume

Advanced · Home Assistant number · volume

Current panel media volume reported on its native 0–100 percent scale.

Ambient light

Basic · Home Assistant sensor · illuminance

Ambient illuminance measured by the panel light sensor.

This row has no value to edit. Its switch decides whether the ambient light level is reported to Home Assistant as an illuminance sensor in lux, which is on by default. The row appears only on a panel whose light sensor actually delivers readings; a sensor that is declared by the hardware but never reports is treated as absent.

Readings are not retained between connections, because a fresh one follows shortly. The same sensor can drive Adaptive brightness, and that works whether or not this entity is exposed.

Related: Adaptive brightness

Proximity

Basic · Home Assistant binary sensor · proximity

Learned near/far occupancy from a supported proximity source.

This row has no value to edit. Its switch decides whether the panel reports near or far as an occupancy binary sensor in Home Assistant, which is on by default. The value comes from a calibration the panel learns from its own proximity signal, so the raw sensor value never reaches Home Assistant.

The row appears only on panels with a proximity source Panel Assistant can learn from. While the panel does not yet have enough evidence, or the sensor stops responding, the entity is unavailable rather than showing a guess. Proximity level gives the same reading as a percentage, and Wake on wave uses the same source to wake the screen.

Related: Adaptive proximity and wake on wave

Proximity level

Basic · Home Assistant sensor · proximity_level

Normalized learned proximity level from 0 to 100 percent; binary sources report 0 or 100.

Auto-sleep activity

Advanced · Home Assistant binary sensor · auto_sleep_activity

Whether the auto-sleep policy is currently holding the panel awake. The Home Assistant entity provides the activity history timeline.

Temperature

Basic · Home Assistant sensor · temperature

Environmental temperature reported by Android's panel sensor.

This row has no value to edit. Its switch decides whether the reading from Android’s ambient temperature sensor is reported to Home Assistant in °C, which is on by default. It appears only on a panel that has such a sensor. Values are rounded to one decimal place, and changes smaller than 0.1 °C are not published.

Note

The sensor sits inside the panel, so it is affected by the panel’s own warmth. Panels with a dedicated room climate sensor report Room temperature instead, and this entity is withdrawn there so Home Assistant does not show two temperature sensors for one panel.

Humidity

Basic · Home Assistant sensor · humidity

Relative humidity reported by Android's panel sensor.

This row has no value to edit. Its switch decides whether the reading from Android’s relative humidity sensor is reported to Home Assistant as a whole percentage, which is on by default. It appears only on a panel that has such a sensor, and changes smaller than one percentage point are not published.

Panels with a dedicated room climate sensor report Room humidity instead, and this entity is withdrawn there so Home Assistant does not show two humidity sensors for one panel.

Room temperature

Advanced · Home Assistant sensor · room_temp

Room air temperature from the panel's supported climate sensor (calibration offset applied).

Room humidity

Advanced · Home Assistant sensor · room_humidity

Relative humidity from the panel's supported climate sensor.

This row has no value to edit. Its switch decides whether the relative humidity from the panel’s built-in climate sensor is reported to Home Assistant as a whole percentage, which is on by default. It appears only on panel models whose profile lists that sensor, such as the Tuya TPA10, and it is read through the same route as Room temperature.

The reading is refreshed about once a minute, and changes smaller than one percentage point are not published. No offset is applied to humidity.

Related: Tuya TPA10

Room temperature offset

Advanced · Default 0 · -20 to 20 · room_temp_offset

Correction (°C) added to the reported room temperature — usually negative, since panel self-heating reads high. Per-panel (depends on mounting), so not cloned by a fleet push.

Diagnostics

IP address

Basic · Home Assistant sensor · diag_ip

This panel's LAN IPv4 address as a sensor.

This row has no value to edit. Its switch adds a diagnostic sensor in Home Assistant that shows the panel’s current IPv4 address on the local network. It is off by default, like every sensor on this card, so the panel adds nothing to Home Assistant until you turn one on.

It is useful for opening the panel’s Configure page from a Home Assistant dashboard, or for spotting that the panel moved to a new address after a router change. The sensor updates when the address changes.

CPU usage

Basic · Home Assistant sensor · diag_cpu

Overall CPU busy percentage (root/su panels; unavailable on sandbox-walled panels).

Memory usage

Basic · Home Assistant sensor · diag_memory

Used RAM as a percentage.

This row has no value to edit. Its switch adds a diagnostic sensor in Home Assistant with the share of the panel’s RAM in use. It is off by default. It works on every panel because the source is always readable, and changes smaller than 3 percentage points are not published.

Android keeps memory in use for caches, so a high value on its own is normal. A value that climbs steadily over days is the pattern worth noticing.

Related: Performance

SoC temperature

Basic · Home Assistant sensor · diag_soc_temp

System-on-chip temperature (root/su panels; unavailable on sandbox-walled panels).

Last boot time

Advanced · Home Assistant sensor · diag_boot

When the panel last booted (a timestamp — HA shows the elapsed uptime).

Wi-Fi network

Advanced · Home Assistant sensor · diag_wifi_ssid

Current Wi-Fi network name while Wi-Fi is the active connection. This can identify a location and enters HA history when exposed; Android may hide it unless network-information permission is available.

Wi-Fi signal strength

Advanced · diag_wifi_rssi

Current Wi-Fi received signal strength in dBm while Wi-Fi is the active connection.

Wi-Fi outages (24 h)

Advanced · diag_wifi_outages_24h

Short Wi-Fi dropouts in the rolling last 24 hours. Counts loss of the panel's active Wi-Fi connection only — Home Assistant or broker outages are never counted. If the panel had to cap what it stores, the sensor's is_lower_bound attribute says the value is a floor.
