I am looking for a virtual device which sends constant or periodic update to manually activate the “constant fan” mode of my furnace to facilitate air circulation around the house.
I am currently using my motion sensor as a trigger, basically whenever it senses a motion, it turns on the furnace fan. (but when the furnace switches to heat mode, it automatically change the fan to auto mode). This works great during day time, but fails during night time.
Also I understand there is a Run Circulate in HVAC smart app which I am using to drive the other furnace right now. (unfortunately if I run this app on both furnaces, neither of them would work properly.
Thanks a lot.
