There is a nice official topic for this app.
I’ve moved it to there.
The device has 3 different “target” temperature values in its memory.
Comfort temperature, economic temperature and the off temperature.
Off temperature is not changeable.
The other 2 are, the gui will always change the comfort mode, even if it would be in the economic mode.
This is just to stop confusion like I addressed in that github issue.
If you press the + or - button on the thermostat when it is in economic mode it will switch to comfort mode, this is done by the thermostatic itself and not Homey, I / Homey can’t change this behaviour.
So Homey has kinda the same behaviour when you move the temperature, so to stop this confusion that happens on the thermostatic, I only show and change the comfort mode from the GUI.
If you press the middle button it will always go to boost mode, this is also not behaviour I can change.
And fully determined by the thermostatic.
His question was that if the thermostatic is in economic mode, that it still would display the comfort temperature target, and not the economic temperature.
But as you already notice on the thermostatic itself, it is really hard to implement well, and this was just what could cause the least amount of confusion.
