I have two attic fans, one in the roof and one on one gable end. Right now they are controlled via a set of switches located in a large closet on the second floor. From the switches I have a separate 12/3 cable running to each fan’s thermostat. These are the switches I am currently using: http://www.leviton.com/en/products/1285-L or https://www.amazon.com/gp/product/B003AUIR5C/
They are a center-off, single pole, double throw. Center is off of course, up gives power to the thermostat so the fan can go on and off automatically based on the temp up there, and down I have wired as a bypass so I can turn the fan on no matter what the temp is. Both switches are mounted in a two gang metal box, about 2-1/4" deep (just so you guys know how much room I have for things)
Is there a smart switch or a combination of switches I can use to replace those two? I’ve been searching and searching but can’t find anything. I’ve been looking at smart relays and all sorts of things but I really don’t have room to put anything like that in that box. I’m not even quite sure how the relay would work to be honest.
I basically want to keep the same functionality I have now with the set of SPDT switches but also add the ability to integrate these into my Smart Home setup via SmartThings.
Anyone have any ideas?
