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

• no_occupancy_since: Timeout (in seconds) after which no_occupancy_since is sent. This indicates the time since the last occupancy was detected. For example no_occupancy_since: [10, 60] will send a {"no_occupancy_since": 10} after 10 seconds and a {"no_occupancy_since": 60} after 60 seconds.
• occupancy_timeout: Timeout (in seconds) after which the occupancy: false message is sent. If not set, the timeout is 90 seconds. When set to 0 no occupancy: false is sent.

IMPORTANT: occupancy_timeout should not be set to lower than 60 seconds. The reason is this: after detecting a motion the sensor ignores any movements for exactly 60 seconds. In case there are movements after this 60 seconds, a new message (occupancy: true) will be sent and the sensor will go to sleep for another minute, and so on. Therefore, in order to sustain occupancy: true, you need a reasonable window after this 60s sleep to determine continued occupancy. This is expected behaviour (see #270). To work around this, a hardware modification is needed.

Exposes #

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 %.

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.

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.

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.
