For years now I’ve been using Brian Keifer’s brilliant “Smart Bathroom Fan” SmartApp. This app uses standard drivers to pair together bathroom humidity sensor(s) with a bathroom fan. The idea is to keep the fan running if the humidity is a certain percentage (user settable) different from the running average. It’s worked wonderfully in my bathrooms to keep the humidity down when someone takes a shower.
As we go into this next phase of smartthings, it’s unclear if that smartapp will continue. Does anyone know of a replacement with the new round of smartapps and edge drivers?
I know that requirement isn’t available, but here’s a routine I use with a humidity sensor and a shower fan. Even though the auto off is set for 5 minutes, it never actually shuts off as long as it’s above my setting. I’ve been running this routine for all our bathrooms for as long as I can remember.
Thanks - I came up with something similar as well – I just really like how it deals with the running average. It gets humid here in the summers, and so just saying “if above 80%” will sometimes cause the fan to just run on its own.
It’s not just a matter of rewriting it to use the new API: someone has to pay for the hosting for it since there is no longer a free cloud option. that’s why you see a lot more custom edge drivers (which are allowed to run on the hub itself) versus custom smart apps (which are not allowed to run on the hub).
Sure, you can set up your own server and run it there, but that’s a lot more work than most people are interested in.
I know it’s not the same as the smartapp and it’s a little convoluted but I was able to set up a rule in SharpTools that compares the current humidity against a 10% increase to turn on my fans. To do this you’d have to get the paid version to access variables.
