The humidifier entity is not a standard feature of this thermostat model
…witch entity - Remove switch entity (dps 1) for general availability control - Restore dps 1 as hvac_mode with 'off' state support - Restore dps 104 as cool_heat constraint (hidden) - This allows temperature readings even when thermostat is off
…y default Set floor temperature sensor as diagnostic category since the vast majority of users won't have an external floor temperature probe connected

There seem to be at least 2 variants of this device, with and without humidity. See #3279, #4336, #4527 - Hide the humidity control and the floor temperature sensor if they are not available. - revert the hvac_mode to using 2 dps. #4336 wasn't clear about the problem, and if one variant supports it, it seems unlikely that the other would remain compatible but reject more than 1 dp being changed at once. This is a better compomise than the proposed PR #4529, which just reverts almost all the changes from #4336 completely.
