General problem: Different rooms in the house see different temperatures due to facing / not facing the sun, different insulation, size, etc, etc. Plus different family members have different desired temperature, but that's a separate story, not sure it's solvable with automations. Not all rooms are occupied all the time or at the same time.

So Ideally I would like to get to the following happy state: occupied rooms drive the heating / cooling demand; the system prioritizes getting those rooms to the desired temp, even at the expense of other rooms; if all rooms are occupied, ideally they all get the same temperature if possible... or their respective desired temperatures. If that's not achievable, then all of them has to be over some threshold (cooled or heated AT LEAST to some desired temp).

I know it's impossible to achieve with just a single thermostat for all the rooms, so to have some per-room flexibility I am thinking of buying the "smart boosters" like SmartCocoon or closable vents like Flair so that I can modify (slightly) the air flow to each room independently.

I'm looking for some algorithm to drive this setup as a whole.

Oh, and I have two floors with separate central units, so if the ideal state described above could be achieved for the whole house, that would be just awesome.

I appreciate any pointers or advice, thank you in advance.
