Schedule variant day/hours

Configuration
1

Hello :slight_smile:

I have home assistant installed on my old raspberry (with mosquitto) to interact with my esp8266.
It works for seeing sensors and enable switches commands.

Now I want to be ables to modify some parameters in my esp programm.
The esp is used to control the heating of the house and i don’t want home assistant to do the logic, only the control.

How can i send the hour/days to my esp (and then read them) to schedule the heating?
Is there a special component or must i use a variant tab? (i see the trigger component, but i thinks it is only used to do the automation in home assistant that I doesn’t want)

I heard about data_template, but i don’t know if it could do the job?

I have several variant to affect :

Thanks for your idéas :slight_smile:
