This Node-Red module contains single "Xiaomi BLE" node that gets all known data from Xiaomi BLE (Bluetooth 4) devices using Bluetooth 4 compatible adapter.
Currently supported devices are:
- MiFlora - Xiaomi Mi plant sensor
- Xiaomi Mijia Bluetooth Temperature Humidity Sensor
This module requires noble library. It will be installed automatically but in case of any problems you can try to install it manually using corresponding instructions.
To install this module use Node-Red GUI installer or console command:
npm install node-red-contrib-xiaomi-ble
Configuration: Xiaomi BLE node needs only bluetooth address of devices (optional, if it's omitted then incoming message should have address property)
Input message: just triggers requesting data from the sensor. Optional parameters:
- address - override address of the device from configuration.
- scan - re-lookup for device even if it was already found before.
Output message: msg.payload object of the output message could contain next fields:
- temperature - temperature from sensor
- battery - battery level in percents
- humidity - Mijia Temperature Humidity device only
- light, moisture, conductivity - MiFlora device only
On Linux bluetooth adapter could be used by root user only.
