Sensors	sensors

The Wear OS app also offers sensors to consume your wearable data in Home Assistant, please refer to the link to learn more about how sensors update on Android. Not all sensors offered by the phone app will be offered by the Wear OS app. Please see the list below for what sensors are currently supported by the Wear OS app. If a sensor requires permissions you will be prompted to accept, otherwise the sensor will not enable and send data.

It's important to note that sensor updates require the app to post a notification to the device in order to prevent it from being killed by the OS. You can go to into Wear device settings and turn off the SensorWorker Notification channel to stop these notifications from buzzing on your wrist.

:::info Sensor updates are dependent upon the watch having data connectivity and the app being allowed to send an update. Some devices implement stricter battery saving techniques than others so updates may not happen as frequently as you would expect.

There is currently no support for sensor settings. Some sensors may not be fully operational as a result. For example, the BLE Transmitter and Beacon Monitor sensors can only be enabled, none of the settings can be changed as of this moment. These sensors may not be completely functional while we work on adding sensor settings, the default settings will allow for primary functionality. :::

Sensor List

Sensor	Attributes	Description
App Data	None	Sensors that show how much data was sent or received by the app.
App Importance	None	The current importance of the app to determine if its in the foreground or cached.
App Memory	None	Information about the memory that is available for the app.
App Usage	None	Sensors that represent how the app is treated based on its usage.
Audio	None	Several different sensors around different types of audio detection from the device.
Battery (enabled by default)	None	Several different sensors around the state of the devices battery. Only battery_level, battery_state and charger_type enabled by default.
binary_sensor.bedtime_mode	None	A sensor to reflect the state of Bedtime mode on the device. For best results enable Do Not Disturb or Interactive sensor. Only available on Wear OS 3 devices
Bluetooth Sensors	See Attributes	Several different sensors about the state of bluetooth on the device. Sensors are also available for beacon transmitting and monitoring.
sensor.current_time_zone	See Attributes	The current time zone the device is in.
Current Version	None	The current installed version of the application.
Do Not Disturb	None	The state of do not disturb on the device.
Doze	None	Whether or not the device is in doze mode.
Health Services	See below	A group of sensors provided by the Health Services API.
sensor.heart_rate	Accuracy	Current heart rate in beats per minute. This sensor makes use of the heart rate sensor.
Interactive	None	Whether or not the device is in an interactive state.
Keyguard Sensors	None	Sensors that represent various states about the device being locked or secured.
sensor.last_reboot	See Attributes	The timestamp of the device's last reboot.
Last Update	None	The state will reflect the intent that caused the last update to get sent.
sensor.light_sensor	None	The current level of illuminance the device detects.
Mobile Data Sensors	None	Several different sensors around the state of mobile data.
binary_sensor.nfc_state	None	Whether or not the device has its NFC sensor enabled.
sensor.phone_state	None	The only tracked states are idle, ringing or offhook, no other information is accessed.
sensor.pressure_sensor	None	The pressure reading from the device.
sensor.proximity_sensor	None	The current proximity reading from the device, certain devices will only show boolean value of near or far.
Network	None	Several different sensors around the state of WiFi.
Next Alarm	See Attributes	Date of the next scheduled alarm.
binary_sensor.on_body_sensor	None	A sensor to indicate whether the wearable believes it is on the body or not. This sensor makes use of the low latency off body detection sensor.
Power Save	None	Whether or not the device is in power saving mode.
sensor.screen_brightness	See Attributes	The current value of screen brightness.
sensor.screen_off_timeout	None	The current value of screen off timeout setting.
sensor.sim_1	See Attributes	Name of your cellular provider.
sensor.sim_2	See Attributes	Name of your cellular provider.
Steps	None	The number of steps taken from the user since the last device reboot. Requires activity recognition permissions on supported devies.
Storage Sensors	See Attributes	The amount of total and available internal & external storage on your Android device.
binary_sensor.theater_mode	None	A sensor to reflect the state of Theater mode on the device. For best results enable the Interactive sensor.
Traffic Stats Sensor	None	Amount of data transmitted and received from mobile and total device usage since last reboot.
binary_sensor.wet_mode	None	A sensor to indicate the state of Wet Mode on the current device. This sensor is also known as Touch Lock or Water Lock on some devices. This is a special mode where the user must press and hold the crown/power button for 2 seconds to re-enable touch.
