Notes

Controlling

Get local temperature in degrees Celsius (in the range 0x954d to 0x7fff, i.e. -273.15°C to 327.67 ºC)

{
    "local_temperature": ""
}

Get or set offset added to/subtracted from the actual displayed room temperature to NUMBER, in steps of 0.1°C

{
    "local_temperature_calibration": "NUMBER"       // Possible values: –2.5 to +2.5; leave empty to read
}

Set temperature display mode

{
    "temperature_display_mode": ""      // Possible values: 0 to set °C or 1 so set °F
}

Get room occupancy. Specifies whether the heated/cooled space is occupied or not. If 1, the space is occupied, else it is unoccupied.

{
    "thermostat_occupancy": ""
}

Get or set occupied heating setpoint to NUMBER in degrees Celsius.

{
    "occupied_heating_setpoint": "NUMBER"       // Possible values: MinHeatSetpointLimit to  MaxHeatSetpointLimit, i.e. 7 to 30 by default; leave empty to read
}

Get or set unoccupied heating setpoint to NUMBER in degrees Celsius

{
    "unoccupied_heating_setpoint": "NUMBER"       // Possible values: MinHeatSetpointLimit to MaxHeatSetpointLimit, i.e. 7 to 30 by default; leave empty to read
}

Increase or decrease heating setpoint by NUMBER degrees in °C.

{
    "setpoint_raise_lower": {
    "mode": "0x00",       // Possible values: see table below
    "amount": "NUMBER"    // Possible values: signed 8-bit integer that specifies the amount the setpoint(s) are to be increased (or decreased) by, in steps of 0.1°C
    }
}

Get or set whether the local temperature, outdoor temperature and occupancy are being sensed by internal sensors or remote networked sensors

{
    "remote_sensing": "NUMBER"      // Possible values: see table below; leave empty to read
}

Get or set control sequence of operation

{
    "control_sequence_of_operation": "VALUE"       // Possible values: see table below; leave empty to read
}

Get or set system mode

{
    "system_mode": "VALUE"       // Possible values: see table below; leave empty to read
}

Get running state

{
    "running_state": ""       // leave empty when reading
}

Possible values:

Valve position / heating demand

{
    "pi_heating_demand": 0       // leave empty when reading
}

Will report the valve position or heating amount depending on device. 0=min, 255=max

Get or set weekly schedule

{
    "weekly_schedule": {
    "TemperatureSetpointHold": "0x00",                // 0x00 setpoint hold off or 0x01 on
    "TemperatureSetpointHoldDuration": "0xffff",      // 0xffff to 0x05a0
    "ThermostatProgrammingOperationMode": "00xxxxxx"  //see table below
    }                                                   // leave empty to read
}

Clear weekly schedule

{
    "clear_weekly_schedule": ""
}

Options

How to use device type specific configuration

• thermostat_unit: Controls the temperature unit of the thermostat (default celsius). The value must be one of celsius, fahrenheit

Exposes

Battery (numeric)

Remaining battery in %, can take up to 24 hours before reported. 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 %.

Climate

This climate device supports the following features: occupied_heating_setpoint, local_temperature, system_mode, running_state, local_temperature_calibration, pi_heating_demand.

• occupied_heating_setpoint: Temperature setpoint. To control publish a message to topic zigbee2mqtt/FRIENDLY_NAME/set with payload {"occupied_heating_setpoint": VALUE} where VALUE is the °C between 7 and 30. To read send a message to zigbee2mqtt/FRIENDLY_NAME/get with payload {"occupied_heating_setpoint": ""}.
• pi_heating_demand: Position of the valve (= demanded heat) where 0% is fully closed and 100% is fully open. To control publish a message to topic zigbee2mqtt/FRIENDLY_NAME/set with payload {"pi_heating_demand": VALUE} where VALUE is the % between 0 and 100. To read send a message to zigbee2mqtt/FRIENDLY_NAME/get with payload {"pi_heating_demand": ""}.
• local_temperature: Current temperature measured on the device (in °C). To read send a message to zigbee2mqtt/FRIENDLY_NAME/get with payload {"local_temperature": ""}.
• system_mode: Mode of this device. To control publish a message to topic zigbee2mqtt/FRIENDLY_NAME/set with payload {"system_mode": VALUE} where VALUE is one of: off, auto, heat. To read send a message to zigbee2mqtt/FRIENDLY_NAME/get with payload {"system_mode": ""}.
• running_state: The current running state. Possible values are: idle, heat. To read send a message to zigbee2mqtt/FRIENDLY_NAME/get with payload {"running_state": ""}.
• local_temperature_calibration: Offset to add/subtract to the local temperature. To control publish a message to topic zigbee2mqtt/FRIENDLY_NAME/set with payload {"local_temperature_calibration": VALUE}.To read send a message to zigbee2mqtt/FRIENDLY_NAME/get with payload {"local_temperature": ""}.The minimal value is -12.8 and the maximum value is 12.7 with a step size of 0.1.
