Boiler enable

[Chip2786]

What is the feature?

Enable the "call for heat" on a boiler

Description

I would like to be able to add my boiler control switch (in my case its a Shelly 1 Smart switch) into the Tstat so;

if Any stat is in "heat" mode = Boiler on if All stats are in "off" mode = Boiler off

Additional Information

Currently im doing this via Node-Red but its messy and would be much nicer all in one location

this be nice.

Currently using a template sensor

{{ ['climate.badkamer_trv', 'climate.living_room_trv','climate.keuken_trv','climate.bedroom_trv','climate.bedroom_2_trv'] | select('is_state_attr', 'hvac_action', 'heating')| list | count }}

and the shelly for the boiler checks if the sensor is above a treshold. Would be nice if you could at a boiler entity which just has a treshold setting and counts the better thermostates entities

I would like this as well, additionally I would also like to control an opentherm thermostat using a temperature offset.

Practical example: I want to heat my bedroom but not my livingroom where the OpenTherm thermostat lives. If I increase the target temperature in my bedroom by 2°C, I want to offset the current measured temperature on my opentherm thermostat by 2°C and configure that as the setpoint.

This way the boiler can still modulate its power due to the low heat demand.

Would love this feature. To be able to send a command to activate a relay to turn on my combi boiler
