If you have an Under Floor Heating then you’re most likely to have the bathroom without a thermostat but in an open loop that has it circulation always on, and with the new temperature sensors around like Shelly and others if you want to combine those with some kind of an electric heater somewhere in the house or as mentioned before in the bathrooms it would be great to have existing Thermostat Card(s) accept the room temperature, set temperature, and an on/off switch entities from the existing entities in HA to control that while keeping the same look and feel of the UI instead of having them built custom using other than thermostat cards.
Don’t you agree?
