After I posted this topic, they changed some stuff in smartthings, my routines stopped working. So what I ended up doing was using smartthings to create a virtual switch that triggers the motion detector between sunrise and sunset then used IFTTT with the Rachio service to turn on the sprinklers. When the virtual switch triggers it runs the IFTTT script. There is a setting in the IFTTT script to limit the time to 1 minute. Creating the virtual switch is easy in the Smartthings Classic app but more complicated in the new app. You should be able to find a video on YouTube that will show you how to make a virtual switch on the new app.
I figured this out with the help of Zooz’s support team. If you have problems they are very helpful. Contact me if you need more help. And, by the way, this works this week but all bets are off the next time SmartThings changes the software for the hub. Seems like I reinvent this thing once a year.
