Backdoor Communication for Lufft Weather Stations


Lufft weather stations use a universal address (ID = 200) in the instance that the device ID is unknown. For pre-configured sensors with altered communication protocols, there is a 10-second window after powerup where it is set to the default UMB protocol, and the software can communicate. If the communication protocol on a Lufft device has been changed, follow the backdoor communication technique for reconnecting the device in the Configtool.NET software.

Known Device IDs

If the Device ID is known,

  1. Open a new or existing workspace and create a device with the proper device class (WSx-UMB) and ID.
  2. Click on the device.
  3. Hit the gear icon at the top of the “Device Details” page.
  4. Cycle power on the Lufft.
    1. The “Not connected” display will now show “Connected” with the device information.
    2. Click “Read from Device” to see the sensor configuration.
