Hi

I am trying to figure out how to automatically turn off the bathroom fan after a 15 minute delay.   So the scenario is that the customer turns on the fan and then leaves the room.   15 minutes later, the fan automatically turns itself off.

I tried to create a schedule that says Wait 15 minutes and then switch fan OFF but the only trigger that I can find is based on the current time not on the change of state when the bathroom fan turned on.

I am perplexed that the Schedule is only time base and does not give me any more flexibility.   What am I missing???

Does anyone have any ideas ?    I thought about baking it into a scene but the scene will only let me do immediate actions not delayed actions.

 

Thank you

A simple program will work:

IF

    Batheoom fan is on

THEN

     wait 15 minutes

     turn bathroom fan off

ELSE

Thank you for your suggestion.   That is similar to what I was thinking.  So I created a program (see attachments) but when I turn on the bathroom fan, the program does not trigger.   The fan stays on.

Is there something that I have missed?

I apologize for the redundance but I inadvertently put this post in the eisy thread which I realized after is really more hardware related.   My question is strictly software.

Instead of using "control" (is switched on) use the "status" for the If command. That way the Wait statement will execute for it's time interval. Test it with a short time initially, like 15 seconds.

Merci Guy

Changing to Control vs Status did the trick.
