Notes

Adapter firmware

In order for this device to work, at least the following firmware is required on your adapter:

Note that if you have already paired the device you will need to repair it after upgrading your adapter firmware.

Pairing

Press and hold the reset button on the device for +- 5 seconds (until the blue light starts blinking). After this the device will automatically join. If this doesn't work, try with a single short button press.

RTCGQ12LM pairing

Note: When you fail to pair a device, try replacing the battery, this could solve the problem.

OTA updates

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

Options

How to use device type specific configuration

  • occupancy_timeout: Time in seconds after which occupancy is cleared after detecting it (default is "detection_interval" + 2 seconds). The value must be equal to or greater than "detection_interval", and it can also be a fraction. The value must be a number with a minimum value of 0

  • no_occupancy_since: Sends a message the last time occupancy (occupancy: true) was detected. When setting this for example to [10, 60] a {"no_occupancy_since": 10} will be send after 10 seconds and a {"no_occupancy_since": 60} after 60 seconds. The value must be a list of number.

  • illuminance_calibration: Calibrates the illuminance value (percentual offset), takes into effect on next report of device. The value must be a number.

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

Exposes

Occupancy (binary)

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

Illuminance_lux (numeric)

Measured illuminance in lux. Value can be found in the published state on the illuminance property. It's not possible to read (/get) or write (/set) this value. The unit of this value is lx.

Illuminance (numeric)

Measured illuminance in lux. Value can be found in the published state on the illuminance property. It's not possible to read (/get) or write (/set) this value. The unit of this value is lx.

Detection_interval (numeric)

Time interval for detecting actions. Value can be found in the published state on the detection_interval property. To read (/get) the value publish a message to topic zigbee2mqtt/FRIENDLY_NAME/get with payload {"detection_interval": ""}. To write (/set) a value publish a message to topic zigbee2mqtt/FRIENDLY_NAME/set with payload {"detection_interval": NEW_VALUE}. The minimal value is 2 and the maximum value is 65535. The unit of this value is s.

Device_temperature (numeric)

Temperature of the device. Value can be found in the published state on the device_temperature property. It's not possible to read (/get) or write (/set) this value. The unit of this value is °C.

Battery (numeric)

Remaining battery in %. 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 %.

Voltage (numeric)

Voltage of the battery in millivolts. Value can be found in the published state on the voltage property. It's not possible to read (/get) or write (/set) this value. The unit of this value is mV.

Power_outage_count (numeric)

Number of power outages. Value can be found in the published state on the power_outage_count property. It's not possible to read (/get) or 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.
