all, figured I would take some time to post stuff to help out others.
I used a zooz zen32 as a count down timer for my bathroom fan. (sorry it's very dirty, that one is right next to the garage and I use my dirty fingers on it all the time.)
as a side note, I engrave the zen32 myself. some of you guys here have been super helpful to me for the past 6-8 months (3 names that comes in mind: Bobby, Lewis and rlithgow1, and there are probably more that were helpful, so sorry if I forgot your name). so ill be happy to send a few custom engraved zen32 faceplate to those individuals if they currently run zen32.
and here are the Rule Machine running it my zen32 countdown timer.
when the fan turns off (either by someone pressing the off button or after time runs out). turn off all leds (Garage-salleDeau-KP is the zen32 device)
the RM that turns off all leds on the zen32. I call this one frequently.
the 15 minutes Rule Machine
the 30 minutes (I assume you can imagine what is the 45 and 60 minutes code... almost the same with obvious changes
hopefully that can help someone
