Thanks, Dan. I thought the same. Last year I did this in the menu program and it worked. However, it seemed that both the interval program and the menu program could not co-exist. If I start both programs up and ran a station from the menu program the interval program would no longer be able to control the sprinklers. It seemed like there was a GPIO conflict in doing things this way. Maybe I just need to dig in to it more and see why they conflicted.

I’d appreciate any thoughts you or anyone else has on why they would conflict. Thanks again.

**Edit – I tried again and this is the error I’m getting: “RuntimeWarning: This channel is already in use, continuing anyway.” when I called GPIO.setup(). It says “continuing anyway” and the program starts. However, as I said, it can’t actually control the sprinklers after that point.
