Thank you all for your replies so far. I’m afraid the most helpful one came from Udo Hartmann: not possible.
I’m aware of the options to have several graphs in one chart, and also of the option to switch charts. But the basic idea is to have the whole house at a glance so that I can better understand which radiator has which effect):
- ten “rooms” (including one thermometer per level in the staircase)
- actual and target temperature in each chart
that would result in twenty graphs per chart. Tried that, was pretty unintelligible.
Switching through the various graphs has the big advantage that correlations are very visible, but flipping through all possible combinations of correlating rooms is very hard to manage.
What I’m trying to do is to set up a NASA-like control center for temperature, open doors, open windows for the entire house so that I can optimize the dependencies between open doors, open windows and target temperatures.
For example, my subjective experience is that in my office in the basement, temperature changes when we open doors and windows on the first floor to let fresh air into the sleeping rooms, but not enough to trigger the thermostat’s “window open” reflex. so it would make sense to adjuts the target temperature in the basement until everything is closed again, or to even disable that radiator for a certain time.
… and so on …
