Notes

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.

Troubleshooting: device stops sending messages/disconnects from network

Since Xiaomi devices do not fully comply to the Zigbee standard, it sometimes happens that they disconnect from the network. Most of the times this happens because of the following reasons:

• Device has a weak signal, you can see the signal quality in the published messages as linkquality. A linkquality < 20 is considered weak.
• Low battery voltage, this can even happen when the battery still appears full. Try a different battery.
• The device is connected through a router which cannot deal with Xiaomi devices. This is known to happen devices from: Centralite, General Electric, Iris, Ledvance, OSRAM, Sylvania, SmartThings, Securifi.

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.

• pressure_precision: Controls the precision of pressure values, e.g. 0 or 1; default 1. To control the precision based on the pressure value set it to e.g. {1000: 0, 100: 1}, when pressure >= 1000 precision will be 0, when pressure >= 100 precision will be 1.

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

Manual Home Assistant configuration

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