I read you blog post and the Heating Controls Grant page

good luck for your grant!

ouch! standards in home automation... good luck :-S

I'm definitely not an expert in this matter but I'm hacking since 2016 in my
spare time

home automation systems are composed by a controller and a set of
sensors/actuators, I want a _full_stack_free_sofware_ solution in my home,
including actuators and sensors

an interesting source of info is, see for an introduction on the

unfortunately many actuators/sensors comes with proprietary software
installed and no way to replace it with a free one is one of the major free software home automation
controllers and is able to interface to **a lot** of components (sensors and
actuators) on the market:, climate

one of the components is the Generic Thermostat
you could use to tunr on/off your zone heating system based on the
temperature reported from a sensor from the same zone... this obviously
works only if you have one heating system for each zone (rare case, I guess)

in my home (Italy) I have a central heating system and each radiator is
controlled by a manual valve, I'm still searching a way to interface a
controller (i.e. home-assistant) whith **free software** remotely controlled
radiator valves; this is an example of the current results:

the problem is the "devices" (aka actuators, like radiator valves for
example) part of the infrastructure: I'm not aware of a free software
operated one
