BAXI Mago with GW-16 creating Device with no entities

[srodighiero]

Hi,

The integration is setup with success, but as in title, it creates the device (the gateway) but no entities, any ideas/suggestions?

Thank you

This the logs:

NOTE: I have still to connect the GW-16 to the boiler, could it be this the reason of the problem?

As predicted, the reason was that the boiler was not connected yet. Maybe you can use these logs to improve the config flow/ui and report maybe a warning message or similar. I would in any case suggest to add this note to the README.
