Knowing if attic fan is running


#1

I have an attic fan that I need to know if it is running. I have a GE Energy Reading switch that is on all the time. The fan draws 5 amps on running so the switch is fine as it handles a 1/2HP motor. I can see the switch is on but I need a visual indicator that the fan itself is running. Any ideas would be appreciated.

Tack a piece of paper somewhere and point a motion sensor (with a tube) at it? :slight_smile: It might take some trial and error.


#3

I was thinking more like when the amps are above 2 then turn on a virtual switch. Is there a way to write this.

If you look at your IDE and study the power draw of that fan, you should be able to tell when the fan is on. Based on that, you can write a piston that alerts you if the power is less than what you’re expecting for a specified amount of time.

Here is what I wrote, does it look correct? Switch 20 is a virtual switch for indicator in SmartThinmgs and ActionTiles.


#6

If you know the least amount of power it uses on the lowest setting then I’d probably use that… something like Outlet power stays less than xxW for Y minutes.


#7

So what I have won’t work? I don’t want the stays less than as I am not sure how long the fan will stay on do to temp and humidity. It is an automatic fan to ventilate the attic.

Oh it will work. I was thinking the fan was always on hence my suggestion.

Thank you, I usually take your advice as you know a hell of a lot more than I do in this.
