I have a Fan in the basement to bring cold air to the attic. Here are the hardware components I’m using to make this possible, but need some automation adjustments.
If the basement temperature is 10 degrees cooler than the attic and the attic is over 78, then turn it on for 10 minutes, and check again. I would also like to add some way to check presence in the room first but don’t have any sensor yet. Since I have computers in the attic I guess I could do something like, if the computer is been used then trigger…
I’ve done a bunch of automations like that, and have found simpler paths.
First, setup a Generic Thermostat component. Configure it for cool mode
Get this working so your fan comes on when the attic is over the setpoint in the thermostat.
Next, you only want the thermostat in cool mode if the difference in temperature between attic and basement is greater than 10 degrees. Setup a binary sensor template that is true when it is greater than 10.
Lastly create two automations. One that runs when that binary sensor is True and one that runs when it is false. And within turn the thermostat to off or cool mode.
I have a terrabloom inline fan as well, and Id love to be able to control it in HA. Is there config already made to do so with this fan? I have a remote for it already but prefer HA
