Electric water boiler allowed to heat only x hours per day setup ideas.

[Lipown]

Hello, I would love to use the this thermostat but I am lost how I shall change my whole automation.

• I have no smart valves. Only water boiler that drive hot water to radiators in each room.
• Each room has temp sensosr, thermostat entity created in HA
• Each thermostat in HA has set heater to input_boolean entity
• Those input_booleans are grouped. If any thermostat request heating it will turn the status of group to "ON"
• Automation then triggers switch of electric water boiler.
• Automation is turned on only for x cheapest hours of electricity during day.

Now above means that if automation triggering boiler is off the thermostats might be still on which would confuse HASmartThermostat.

I do not want to automate turning the heating off on thermostat because those thermostats are also controlled manually.

Any ideas how I could implement HASmartThermostat into my setup? Am I able for example to turn PID function off during automation for triggering boiler is off?

Thanks!

Huh... Another set of thermostats (user-facing); setpoints/states are copied from them to "hidden" HASmartThermostats; HASmartThermostats are forcefully disabled by automation during not-so-cheap hours?
