First of all I am very new to HA. So I may be asking what seem like obvious questions to some. Sorry for that.
I have a configuration which is fairly common in Europe in which I have a radiator in each room/zone that is controlled by a thermostatic valve. There is a separate system that heats the water, in my case both a solar heater and a heat pump. These are used to heat both the domestic water and provide water for the heating. There is a pump that can be switched on to provide hot water to the radiators.
Off course I could leave this pump running the whole time, but that us wasteful. So I want to crate an automation that determines if any of the thermostats is open - even a little - and turn on the pump. However, if all of the radiators are closed, then I want to turn the pump off.
I can then control the radiators separately in each zone by ToD, DoW, MoY, …
I use Tado thermostats and the integration is great. So what I want to do is create an automation that is triggered if any of the thermostats turns on or off. I will have around 10-15 thermostats in the house so I want an automation that will loop through however many thermostats there are in the system to determine if the heating pump should be on or off.
I’ve looked through the templates and I saw one to test the battery of the all of the radiators, and then send a message. But this is run on a regular cadence rather than being triggered by an event.
I’d love to get some pointers from the community, even if it is pointers to something similar.
