"Not all required fields are filled in" error when adding integration

[Sciamano72]

Hello everyone.
I've just installed my Sonoff TRVZB valves on my heaters, and wanted to command them using the Better Thermostat integration.
I've installed v1.6.0 because I've read that later versions have problems with these TRVs.

When I try to add the integration and fill the form this happens:

I can't seem to understand what required field isn't filled in....

Thanks!

Ok, scratch that. It seems like HA had a few hiccups when restarting and everything wasn't ready yet when I tried adding the integration.
After HA correctly loaded everything, the form was complete (and different).
Sorry for posting too early.
