My house is from 1955 if I can do it so can you lol.
I did not run a C wire.
I ran a 24 volt power supply to it.
I’m using a Nest thermostat with no C wire
This might’ve already been stated but it would be nice if the thermostat could send notifications when certain temperature is reached. So if I had a sense Contact sensor on a window that was open the temperature hits a certain degree the thermostat send me a notification and I can go then shut that window. Or vice versa if it gets warm enough I can get a notification and go open that window.
