Custom ADB Sensor

Custom ADB Sensor is a highly flexible Home Assistant custom component that allows you to create sensors based on the output of ADB commands. Use it to monitor various aspects of your Android TV, Fire TV, or any ADB-compatible device. This repository includes a sample configuration for detecting the current app on Android TV/Fire TV by parsing the mCurrentFocus output.

Features

• Supports any ADB command to create custom sensors tailored to your needs.
• Designed for easy integration with the androidtv.adb_command service.
• Provides raw ADB response data as state attributes for debugging or additional logic.
• Includes an example for detecting the currently open app on Android TV/Fire TV.

Installation

Manual Installation

1. Clone or download this repository.
2. Copy the custom_adb_sensor folder into your Home Assistant custom_components directory.
3. Restart Home Assistant.

HACS Installation

Add this repo in HACS to stay up-to-date.

Configuration

Add a sensor configuration to your configuration.yaml file. Here's the example for detecting the currently open app on an Android TV/Fire TV device:

sensor:
  - platform: custom_adb_sensor
    name: Fire TV Current App
    adb_entity_id: media_player.fire_tv_192_168_1_202
    adb_command: "dumpsys window | grep mCurrentFocus"

or better:

sensor:
  - platform: adb_sensor
    name: Fire TV Current App
    adb_entity_id: media_player.fire_hd_8_12th_gen_adb
    adb_command: "dumpsys window | grep mCurrentFocus"
    value_template: >
      {% for line in value.split('\n') %}
      {% if "mCurrentFocus=" in line %}
      {{ line.split('=')[-1].split('{')[-1].split('}')[0].split()[-1] }}
      {% endif %}
      {% endfor %}

Parameters

Parameter	Description	Required	Default
name	The name of the sensor.	Yes	ADB Sensor
adb_entity_id	The entity ID of the Android TV/Fire TV media player.	Yes	None
adb_command	The ADB command to run.	Yes	None

Example Use Case: Detect Current App

The example above will run the dumpsys window | grep mCurrentFocus command to extract the mCurrentFocus value from the ADB response and display the currently open app as the sensor state.

Advanced Configuration

You can extend the sensor to support other ADB commands. For example:

Monitor Lockscreen Status

sensor:
  - platform: custom_adb_sensor
    name: Fire TV Lockscreen Status
    adb_entity_id: media_player.fire_tv_192_168_1_202
    adb_command: "dumpsys window | grep mDreamingLockscreen"

The state will update to "Locked" or "Unlocked" based on the ADB output.

Custom Logic

The component can be adapted to parse custom data from any ADB command output. Review the sensor.py file for details on how to add your own parsing logic.

Debugging

The raw ADB response is stored in the adb_response attribute of the sensor for easy debugging or creating templates.
