Recommendable wired heating control system

[MDAR (Stuart Hanlon, UK importer of Velbus hardware)]

@Marlow

So all I would need to achieve is to read out that temperature and push it to some sort of input, where the Velbus system can react to it.

Arrr, again you can’t push a value into a VMB4AN, you can only read the values, or the output states that the logic inside the VMB4AN decides.

@Marlow

The VMB4AN module sounds like one step in the right direction.

Not really, because of the above.

However… Not to be outdone…

There’s no reason why the Thermostat logic can’t be done in a stand alone openHAB2 / Node-RED instance and push relay status updates into Velbus relays. (Or any other brand for that matter)

It wouldn’t be my first choice, but there are plenty of examples of people using openHAB2 as Thermostats with very advanced timings.

@ThomDietrich Thermostat boilerplate would be an excellent start.
