I am new to this and having trouble thinking through the different things and how to make them work together.
I have a dual fan whole house fan. I can turn each on and off through Smart Life via IFTTT.
What I want to do is turn the fans on whenever the outdoor temp (via WU) is 3 degrees less than the inside temp (via Nest) and the Nest is set to cool. In the same or different flow I want to turn off one of the fans if the outdoor temp drops below 60 degrees and turn it on again when the temp rises above 60 degrees.
Once the outdoor temp has dropped more than 5 degrees below the indoor temp,and then rises back to within 5 degrees, I want to turn both fans off.
As other humans can tun the fans on and leave them, I would like to regularly check and see if the outdoor temp is within 2 degrees less to any amount hgher than the indoor temp to turn off both fans.
Can the IFTTT applets be resued in these flows? There are only four commands, fan 1 off/on, fan 2 off/on.
There are always windows cracked open, so turning the fan on should not cause a problem.
If anyone has others ideas as to how to keep the house cool, I would love to hear it.
Ultmately, I want to do something similar/opposite when Nest is in Heat mode.
