My heating is old, but makes a very good job, so there is no real need to replace it. The only downside is that there is (was) no way to start it time triggered or on the way home from work.
With this small upgrade, remote control and regulation in combination with sensors is no problem.
Here you can see the solution in action:

Thanks to @Josar for his excellent tutorial OpenHAB Exec Binding explained in detail on 433MHz radio transmitter example
(I don’t know if it was another bug in my code but maybe the autorun=true of an exec thing is not triggered if the argument has not changed?)

Also thanks to @rlkoshak for the hints in How to solve Exec binding problems and to all others working on openHAB :+1:

Always remember what my shell told me once while working on this :slight_smile: :

... It usually boils down to these three things:

    #1) Respect the privacy of others.
    #2) Think before you type.
    #3) With great power comes great responsibility.

Yes that is so. Explained in the second example for the led stripe of the linked example. :wink:
