RuuviTag Open Source BLE Sensor

The ruuvitag sensor platform lets you track the output of RuuviTag Bluetooth Low Energy devices using the ESP32 Bluetooth Low Energy Tracker Hub. This component will track the temperature, humidity, acceleration and battery voltage of a RuuviTag device with RAWv1 protocol every time the sensor sends out a BLE broadcast. RAWv2 protocol is supported too. Then tx power, movement count and measurement sequence number are also tracked.

    • All options from Sensor.

    • Only available if RAWv2 protocol is used.

Setting Up Devices

To set up RuuviTag devices you first need to find their MAC Address so that ESPHome can identify them. So first, create a simple configuration without any ruuvitag entries but with ruuvi_ble enabled like so:

esp32_ble_tracker:

ruuvi_ble:

After uploading the ESP32 will immediately try to scan for BLE devices. When it detects these sensors, it will automatically parse the BLE message print a message like this one:

Got ruuvi RuuviTag (XX:XX:XX:XX:XX:XX): Humidity: 67.5%, Temperature: 22.97°C,
Pressure: 977.09hPa, Acceleration X: 0.005G, Acceleration Y: 0.017G, Acceleration Z: 1.066G,
Battery Voltage: 3.223V

Then just copy the address (XX:XX:XX:XX:XX:XX) into a new sensor.ruuvitag platform entry like in the configuration example at the top.

Note

The ESPHome Ruuvi BLE component listens passively to packets the RuuviTag device sends by itself. ESPHome therefore has no impact on the battery life of the device.
