Ravelli pellet stove (T009 Navel 2.0 WiFi module)

I have the Same Error 500 Internal Server Error Server got itself in trouble … Help please

Which version are you using ?
If you add the repository in GitHub - vincentwolsink/py-agua-iot: py-agua-iot provides controlling heating devices connected via the IOT Agua platform of Micronova to HACS you will get the latest version then it should work.

Thank you very much, I managed to set it up!

At the moment, however, I do not see available entities, but only the device.I do not see

It’s also listed as an unavailable device for me, but it can be operated. Is probably due to the cloud connection. When I call up the original app, it also takes a while for the device to respond.
It’s just not really a real-time connection, not even via the original app.
