I wanted to do this overnight to keep the racoons from pulling up my new sod! I could buy a motion detector and try to hook it up to a smarthome hub, but 1 minute every 15 minutes is how much I want to water my lawn anyway.
So I tried IFTTT and there's only one if allowed. What I got to work was to hook it up to Google Calendar, and created a event called "trigger rachio" every 30 minutes, manually, which was a pain in the ass, and it did work, but I'd have to create these events every night.
I don't know that the rachio app should be in charge or a strange use case but anyone have any other ideas?
