Go-e binding errors after upgrade to OH 5.1

Add-ons Bindings

Hello,

I just upgraded my OH from 32-bit 4.39 to 64-bit 5.1.0. Almost everything worked seamlessly, but the go-e addon throws a lot of errors which I’m not able to understand:

Actually I have 2 “11KW Homefix” wallboxes installed. Both are running without problems, both with their latest firmware and with OH 4.3 everything was ok.

Thanks for any hints,
