I read somewhere in your comments that you have a vision of making Rachio as central hub for all things backyard. Having said that I have idea of making rachio to run pool automation. Basically to control an array of relays which in turn will run pump, heater, lights etc... One of the important modules I would need is water and outdoor temperature sensonrs so I can use their feed back to alter schedule or current run. Can you recommend any wireless/wired sensors that can be integrated with Rachio? What do you think about my idea in general?
