Long press reset button for 5s until the LED indicator flashes three times, which means the device has entered pairing mode

Device type specific configuration #

How to use device type specific configuration

• temperature_precision: Controls the precision of temperature values, e.g. 0, 1 or 2; default 2. To control the precision based on the temperature value set it to e.g. {30: 0, 10: 1}, when temperature >= 30 precision will be 0, when temperature >= 10 precision will be 1.

• temperature_calibration: Allows to manually calibrate temperature values, e.g. 1 would add 1 degree to the temperature reported by the device; default 0.

• humidity_precision: Controls the precision of humidity values, e.g. 0, 1 or 2; default 2. To control the precision based on the humidity value set it to e.g. {80: 0, 10: 1}, when humidity >= 80 precision will be 0, when humidity >= 10 precision will be 1.

Manual Home Assistant configuration #

Although Home Assistant integration through MQTT discovery is preferred, manual integration is possible with the following configuration:

sensor:
  - platform: "mqtt"
    state_topic: "zigbee2mqtt/<FRIENDLY_NAME>"
    availability_topic: "zigbee2mqtt/bridge/state"
    unit_of_measurement: "°C"
    device_class: "temperature"
    value_template: "{{ value_json.temperature }}"

sensor:
  - platform: "mqtt"
    state_topic: "zigbee2mqtt/<FRIENDLY_NAME>"
    availability_topic: "zigbee2mqtt/bridge/state"
    unit_of_measurement: "%"
    device_class: "humidity"
    value_template: "{{ value_json.humidity }}"

sensor:

    device_class: "battery"
    value_template: "{{ value_json.battery }}"
