Trigger to control exhaust fan with conditions

I wish to turn on my bath exhaust fan 1 min. after the shower lights come on. The fan will then run for 45 min. However if the light is turned on and then off within the first min. nothing is to happen.

I set a variable to reflect the light being on or off. I cannot seem to figure out the next step, since it needs a condition based on the verbal of the light on or off. Do I need two to three separate steps?

Thanks

Trigger 1: when the light turns on, no conditions, turn on exhaust fan with an auto off of 45 minutes and a delay of 1 minute
Trigger 2: when the light turns off, no conditions, remove delayed actions for Trigger 1

I think that's got it, right?

Thanks for the reply. I never knew the remove trigger command existed.

However I cannot seem to get the fan to turn no after the 45 min. I have triple checked that I followed your example, and still the fan does not turn off.

Does the "Sent OFF command" show up in the event log?

Also, is the switch X10, Insteon, or Z-wave?

And can you turn it off from Indigo using a control page or the device window?

I am using RadioRa2.
I can turn the fan on and off from within Indigo
Fan does come on as expected.
There is no off received, and no delay action in the Schedules list

Exactly how do you have the triggers configured?

Re: Trigger to control exhaust fan with conditions

And neither trigger fires when you turn the light on/off? Sounds like the device's state isn't getting updated.

Not sure what to say, but all is working currently. Will keep an eye on this.

Thanks for your help

Re: Trigger to control exhaust fan with conditions

New update with failures.
Did some tracking and it looked like turning off the lights removed the scheduled off command no matter what.
I added a variable for the fan, so if the fan was on (variable true) the trigger to remove the delay was not exicuted. Placed a timer to change the verbal back when the fan turned off when it should.
Not sure if this is the most elegant way, but seems to be working now.
