Variable target temperature #87

Open ketillund opened 5 years ago

ketillund commented 5 years ago

I have a heat pump where I vary the target temperature based on the outside temperature. I have defined several intervals (below -8, -8 to 0, 0 to 5, above 5), and depending on which interval the outside temperature is in, Homey sets different target temperatures. The current target temperature is set in a variable, which is read when sending the target temperature to the heat pump. All this is done using flows.

Can this be done with the Heating scheduler? So instead of directly entering the target temperature into a plan, a variable name is given, and then the current value of the variable is read when the plan is run.

How does that go together with the time (the schedule)?

ketillund commented 5 years ago

Actually, I have two target temperature variables, one for the target temperature when I'm away or sleeping, and the other when I'm at home and awake. Both are set based on outside temperature. So when the schedule changes the target temperature of the heat pump, it uses the "target temperature comfort" variable if it enters "home and awake" mode, or "target temperature eco" variable if it enters "away or sleeping" mode.

Currently I'm using the HeatingController app, but with several zones it requires quite a number of flows, so I was thinking maybe your app would be worth a try.

How do the zones fit into that? You have room thermostats or you really only want to control the pump?

ketillund commented 5 years ago

Sorry, the zone thing has nothing to do with the variable target temperatures. That was just my reason for considering switching from the HeatingController app to your app.

In addition to the heat pump, I have a number of radiator thermostats that are controlled by the Homey (only the heat pump uses variable target temperatures). Currently, I have three zones, and there will be 1-2 additional ones once I'm finished with my setup. It seems that using your app would save me some work, as fewer flows need to be made.

mskg commented 5 years ago

Ok, understood :-)

I would propose you start with the radiators. I'm sure, you can reduce your flows a lot with the app. I'm not sure about the inlet-temperature control. Let's talk after you gained some experience with the tool?
