Why does Thermostat mode on Smart AC Control not work?
All I want the Smart AC Control to do is manage temperatures within a comfortable range. If it's above the acceptable limit, the AC unit should run in Cool mode until it brings the temperature down. If it's below the acceptable limit, the AC unit should run in Heating mode until it brings the temperature up. Schedule variations (to change the range) would be nice-to-have, but the above would be sufficient as a starter, even without time variations.
My Ecobees do this so easily; you don't even think about it. They just sit there maintaining the temperature in range. This should be a no-brainer, and sine-qua-non for a Smart AC Control unit. Don't call it "Smart" if it can't do it.
AIUI, this is what Thermostat mode is for. My Smart AC Control appears to have that functionality. I am offered the option in the App, and it is selected. My Acceptance Range is set to 2C. The Minimum On/Off Time is "On (5 min)". But it doesn't work.
All the "Smart" AC Control seems to be able to do is decide when to turn on in the prescribed mode (Heat or Cold) for that period, based on the Smart Schedule for the unit. So if the room is too hot, but the Smart Schedule is set to Heat for that period, Thermostat mode will not tell the AC unit to cool the room (and vice versa).
Maybe there shouldn't be a Smart Schedule, but if I try to delete all periods, it refuses to delete the last one, which covers every period of every day when there's only one period. So that leaves the AC unit set in Heat or Cool mode continuously, even though Thermostat mode should choose the appropriate mode.
In desperation, I long ago kludged the capability by adding a lot of time blocks in the Smart Schedule, every half-hour in daytime hours, switching from Cool to Heat mode and back. At least that will cool for up to half an hour each hour if it's too hot, and heat for half an hour each hour if it's too cold. But apart from being a ridiculous kludge for a "Smart" controller, this is absurdly inefficient and inexpensive, as the AC unit frequently switches between heating and cooling to the target temperature, rather than leaving the unit off unless the temperature is out of range.
[As a supplemental point, tado keep telling how much energy and money the Smart AC Control is saving. That's pure b****cks on this operating pattern. The AC unit is running more than if I controlled it manually. I assume the counterfactual is laughably improbable in order to make it look like the unit isn't a pile of ****.]
I've been struggling with this for a long time. This is a last desperate attempt to see if anyone knows the cause and solution, before I replace the tado with a genuinely "Smart" controller.
