Garo Wallbox - charge timer: modbus: length in response header '12081' must not be zero or greater than '254'

[m03pchen]

Hello everyone,

I have a Garo wallbox connected to my homeassistant via wifi. The garo_wallbox addon is running on the homeassistant and also displays all values. I can also access the wallbox's web interface via the local IP.

Unfortunately, I always get the following error message in the log with the evcc addon:

"[lp-1 ] ERROR charge timer: modbus: length in response header '12081' must not be zero or greater than '254'"

Current configuration: HA-Core 2024.3.3 HA-Supervisor 2024.03.1 HA operating system 12.1 HA frontend 20240307.0 Garo Wallbox: GLBDCMW-T211FC connected via wifi

No wallbox is displayed under the device settings - only the Volvo. On the overview page, however, the Volvo is always shown as "not connected" even if the charging cable is connected and I start the wallbox via Home Assistant or web interface
