  • co2_calibration: Calibrates the co2 value (absolute offset), takes into effect on next report of device. The value must be a number.

Exposes

Action (text)

button clicks or data from/to UART. Value can be found in the published state on the action property. It's not possible to read (/get) this value. To write (/set) a value publish a message to topic zigbee2mqtt/FRIENDLY_NAME/set with payload {"action": NEW_VALUE}.

Calibrate (enum, l2 endpoint)

Calibration. Value can be found in the published state on the calibrate_l2 property. It's not possible to read (/get) this value. To write (/set) a value publish a message to topic zigbee2mqtt/FRIENDLY_NAME/set with payload {"calibrate_l2": NEW_VALUE}. The possible values are: ZERO, SPAN.

CO2 (numeric)
