Problem with the EV charging station in VRM, Cerbo

Hello,

unfortunately I have a problem with the EV charging station. I can't get communication between Cerbo / VRM and Wallbox working. I tried everything I could think of and the tips I found in the discussions. I connect to Cerbo from Walbox, I see the installation status. Charging an electric car via the web interface works.

Unfortunately, communication does not work the other way around. In VRM, I can only see the Wallbox in the Device List, but that's all, it can't be seen anywhere else (Dashboard and similar). I have Modbus TPC enabled in Cerbo. The HW has the latest FW installed.

Please advise what to try next.

Thank you Ondra

Solved, I have downgraded the Venus OS to the latest official. Careful with betas.

Thank you Lucian. Of course, I tried several beta versions and the official release before writing here. Unfortunately, I must have done something wrong. Thank you for your quick response and help. Ondra
