Characteristics
| Name | Required |
|---|---|
| BatteryLevel | ✕ |
| ChargingState | ✕ |
| Name | ✕ |
| StatusLowBattery | ✓ |
Note: This service is to be used as a Linked Service as status of the parent’s battery level.
Creating Battery Service
To display a battery service you must first create a parent service. Motion Sensor for this example.
Next you must create a battery linked service and select parent service used.
Characteristic Properties
Use the following JSON in your battery characteristic properties so that the Home application displays a BatteryLevel, ChargingState and StatusLowBattery.
{
"BatteryLevel": 100,
"ChargingState":0,
"StatusLowBattery":0
}
Example
Here is a screenshot of the Home app.
And a second of the flow used.
Copyable Node-RED flow:
