Exposes

Gas (binary)

Indicates whether the device detected gas. Value can be found in the published state on the gas property. To read (/get) the value publish a message to topic zigbee2mqtt/FRIENDLY_NAME/get with payload {"gas": ""}. It's not possible to write (/set) this value. If value equals true gas is ON, if false OFF.

Gas density (numeric)

Value of gas concentration. Value can be found in the published state on the gas_density property. To read (/get) the value publish a message to topic zigbee2mqtt/FRIENDLY_NAME/get with payload {"gas_density": ""}. It's not possible to write (/set) this value. The unit of this value is %LEL.

Gas sensitivity (enum)

Gas concentration value at which an alarm is triggered ("10%LEL" is more sensitive than "15%LEL"). Value can be found in the published state on the gas_sensitivity property. To read (/get) the value publish a message to topic zigbee2mqtt/FRIENDLY_NAME/get with payload {"gas_sensitivity": ""}. To write (/set) a value publish a message to topic zigbee2mqtt/FRIENDLY_NAME/set with payload {"gas_sensitivity": NEW_VALUE}. The possible values are: 10%LEL, 15%LEL.

Selftest (enum)

Starts the self-test process (checking the indicator light and buzzer work properly). Value will not be published in the state. 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 {"selftest": NEW_VALUE}. The possible values are: selftest.

Test (binary)

Self-test in progress. Value can be found in the published state on the test property. It's not possible to read (/get) or write (/set) this value. If value equals true test is ON, if false OFF.

Buzzer (enum)

The buzzer can be muted and alarmed manually. During a gas alarm, the buzzer can be manually muted for 10 minutes ("mute"), but cannot be unmuted manually before this timeout expires. The buzzer cannot be pre-muted, as this function only works during a gas alarm. During the absence of a gas alarm, the buzzer can be manually alarmed ("alarm") and disalarmed ("mute"), but for this "linkage_alarm" option must be enabled. Value will not be published in the state. 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 {"buzzer": NEW_VALUE}. The possible values are: mute, alarm.

Buzzer manual alarm (binary)

Buzzer alarmed (manually). Value can be found in the published state on the buzzer_manual_alarm property. To read (/get) the value publish a message to topic zigbee2mqtt/FRIENDLY_NAME/get with payload {"buzzer_manual_alarm": ""}. It's not possible to write (/set) this value. If value equals true buzzer manual alarm is ON, if false OFF.

Buzzer manual mute (binary)

Buzzer muted (manually). Value can be found in the published state on the buzzer_manual_mute property. To read (/get) the value publish a message to topic zigbee2mqtt/FRIENDLY_NAME/get with payload {"buzzer_manual_mute": ""}. It's not possible to write (/set) this value. If value equals true buzzer manual mute is ON, if false OFF.

Linkage alarm (binary)

When this option is enabled and a gas alarm has occurred, then "linkage_alarm_state"=true, and when the gas alarm has ended or the buzzer has been manually muted, then "linkage_alarm_state"=false. Value can be found in the published state on the linkage_alarm property. To read (/get) the value publish a message to topic zigbee2mqtt/FRIENDLY_NAME/get with payload {"linkage_alarm": ""}. To write (/set) a value publish a message to topic zigbee2mqtt/FRIENDLY_NAME/set with payload {"linkage_alarm": NEW_VALUE}. If value equals true linkage alarm is ON, if false OFF.

Linkage alarm state (binary)

"linkage_alarm" is triggered. Value can be found in the published state on the linkage_alarm_state property. It's not possible to read (/get) or write (/set) this value. If value equals true linkage alarm state is ON, if false OFF.

State (binary)

"Preparation" or "work" (measurement of the gas concentration value and triggering of an alarm are only performed in the "work" state). Value can be found in the published state on the state property. To read (/get) the value publish a message to topic zigbee2mqtt/FRIENDLY_NAME/get with payload {"state": ""}. It's not possible to write (/set) this value. If value equals preparation state is ON, if work OFF.

Power outage count (numeric)

Number of power outages (since last pairing). Value can be found in the published state on the power_outage_count property. To read (/get) the value publish a message to topic zigbee2mqtt/FRIENDLY_NAME/get with payload {"power_outage_count": ""}. It's not possible to write (/set) this value.

Linkquality (numeric)

Link quality (signal strength). Value can be found in the published state on the linkquality property. It's not possible to read (/get) or write (/set) this value. The minimal value is 0 and the maximum value is 255. The unit of this value is lqi.
