making it read only?

[bulcke]

How would I go about to make this read only? I only want to read the boiler values, not control them.

Would removing the switch: and climate: controls from the opentherm.yaml be enough?

I think so, I'm looking into this, my boiler can read room temp and setpoint from esphome and do its own thing to modulate, so the opentherm output tset should not try to modulate boiler in that case. So I'm thinking that maybe remove PID thermostat and replace it with a bang bang thermostat that uses a spare gpio pin as a dummy heat action
