I have mine integrated with Smartthings, but don’t really use it much. I’ve played with a few motion sensor automations for the neighbors dog that kept using my lawn as a bathroom (and not picking up), but that was about it. Rachio itself is so incredible, there is really no reason to intervene with an integration.
That being said, I suppose there would be some use for using my door sensors to stop a lawn watering if I were to let the dogs out. Problem being, you have limited control thru the API integrations, so I’m not sure if you could delay watering, or if it would just cancel the watering completely.
