I would like the target temperature from the thermostat to adjust automatically by the current outdoors temperature.
For sample, set Target to 10 degree less than outdoors temperature but never set lower than 75F.
How can I archive that? I don’t have an outdoors sensor. Can that work with a city reported temperature?
I guess that might save you bit of energy, but why not just keep it at a comfortable set point all the time? Anyway you could use the weather plugin to get the outside temp, and a little bit of LUUP to do it. The simple UI as seems to be getting the weather also, so it would not surprise me if that is not accessible some way.
In general if the air conditioning is sized well, it will likely run all of the time when it goes above 85F, and you get whatever it can do for you in terms of temperature inside.

Thanks, the weather tool was a good hint. Installed it and it reads the outdoors temperature. Now, I am using PLEG and in PLEG I am trying now to set a timer as trigger for every hour once - that works already - but now I am lost of how to setup the term: Set Thermostat to outside minus 10 degree but never cooler as 75F.
Input:
OutsideTemp
Condition:
NewSetting OutSideTemp - 10 > 75 ? OutSideTemp - 10 : 75
Action:
Use the Advanced tab to set the thermostat setpoint temperature to the value:
{(NewSetting)}
Glad that helped. As long as you have a weather station fairly close, you should be good.

Richard, thank you. I guess with that settings I don’t even need a timer? It changes the thermostat setting every time the OutSideTemp changes? Is there a way to make the OutSideTemp variable an integer number to avoid to many frequent transmissions to the thermostat?
If you use an the weather plugin … you can control it’s polling interval.
