Has anyone found a way (or should I say, an easy way!) of combining temperature and switch graphs?
Where I have an overshoot in a room (look at this classic from earlier today) it would be great to be able to see the zone switching overlaid.

If I try to do it manually in Photoshop the time axis on both graphs tends to be different, so although alignment is possible it's very fiddly.
BTW, here is the combined graph:

As you can see, it the HR92 wasn't fully open. But it was the only zone calling for heat at the time, and as a result the radiator must have got very hot, very quickly. The HR92 reacted quite rapidly, but not soon enough to stop the overshoot. By which time the rest of the house was warm plus thermal gain was kicking in (this is on a south facing wall).
Domoticz is great for doing this kind of thing - if only there was an easier way to combine graphs!
