Exposes #

Battery (numeric) #

Remaining battery in %. Value can be found in the published state on the battery property. It’s not possible to read (/get) or write (/set) this value. The minimal value is 0 and the maximum value is 100. The unit of this value is %.

Voltage (numeric) #

Voltage of the battery in millivolts. Value can be found in the published state on the voltage property. It’s not possible to read (/get) or write (/set) this value. The unit of this value is mV.

Battery_low (binary) #

Indicates if the battery of this device is almost empty. Value can be found in the published state on the battery_low property. It’s not possible to read (/get) or write (/set) this value. If value equals true battery_low is ON, if false OFF.

State (binary) #

Value can be found in the published state on the state property. It’s not possible to read (/get) or write (/set) this value. If value equals UNLOCK state is ON, if LOCK OFF.

Reverse (binary) #

Value can be found in the published state on the reverse property. It’s not possible to read (/get) or write (/set) this value. If value equals UNLOCK reverse is ON, if LOCK OFF.

Action (enum) #
