- Technoline TX 29 IT (temperature only)
- Technoline TX 29 DTH-IT (including humidity)
- TFA Dostmann LaCrosse sensors (type 30.3147.IT)
Since the sensor change their ID after each powercycle/battery change you can check what sensor IDs are available by using the command-line tool
pylacrosse from the pylacrosse package.
sudo pylacrosse -d /dev/ttyUSB0 scan
Or, when using Docker containers:
docker exec -it <containername> pylacrosse -d /dev/ttyUSB0 scan
If you are using the Home Assistant OS or Supervised installation method, these methods are not available for you. The use of an additional computer to figure out the ID is advised.
For TX 29 DTH-IT sensors you can also read the ID from the display and calculate the ID as followed:
hex2dec(ID_on_display) / 4.
To use your
lacrosse compatible sensor in your installation, add the following to your
# Example configuration.yaml entry sensor: - platform: lacrosse sensors: sensor_identifier: type: SENSOR_TYPE id: SENSOR_ID
Set the data rate in kbps. Special values for well-known settings are:
0: 17.241 kbps,
1: 9.579 kbps,
2: 8.842 kbps.
The following values can be combined bitwise:
1 = 17.241 kbps,
2 = 9.579 kbps,
4 = 8.842 kbps
To setup a LaCrosse sensor with multiple sensors, add the following to your
# Example configuration.yaml entry sensor: - platform: lacrosse device: /dev/ttyUSB0 baud: 57600 sensors: kitchen_humidity: name: Kitchen Humidity type: humidity id: 72 kitchen_temperature: name: Kitchen Temperature type: temperature id: 72 kitchen_lacrosse_battery: name: Kitchen Sensor Battery type: battery id: 72
