Notes

Pairing

To pair this device you have to install the device via its installation code. The installation code can be obtained by scanning the QR-code on the inside of the battery cover with your smartphone. Then get the device into pairing mode. In zigbee2mqtt navigate to "Settings" --> "Tools" and click on "Add install code". Paste the code you got from the QR-code and confirm by clicking "OK" which will get zigbee2mqtt into pairing mode automatically. Wait for your device to be joined.

Factory resetting

To factory reset the device remove one of the batteries. While pressing and holding the device's main button on the front, insert the battery back. As soon as the device's LED is starting to blink orange while showing "RES", release the main button and press and hold it again until the device's LED is lighting up green. The device will then restart into the calibration process and look for a Zigbee network to join. In case something went wrong, the device's LED will start to blink red. The process has then to be start all over again.

OTA updates

This device supports OTA updates, for more information see OTA updates.

Climate

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

• 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 5 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: Temperature used by the heating algorithm. This is the temperature measured on the device (by default) or the remote temperature (if set within the last 30 minutes). (in °C). Reading (/get) this attribute is not possible.
• 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, heat, auto. 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. Reading (/get) this attribute is not possible.
• 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}.The minimal value is -5 and the maximum value is 5 with a step size of 0.1.

Boost (binary)

Activate boost heating. Value can be found in the published state on the boost property. To read (/get) the value publish a message to topic zigbee2mqtt/FRIENDLY_NAME/get with payload {"boost": ""}.
