I am recreating this topic because the thread has been closed and the request was to open a new one if there is an interest.
Short history - Well after months of trial-and-error, I hit a rough spot in that my program went haywire and Rachio watered 2 days at 4+ hours of water, consuming over 1000+ gallons of water each. This draws the attention of the local water district office, which subsequently issued me a citation for over-usage. It’s ironic to spend all of this time and money to get sophisticated on watering, but ends up with a citation. They visited us, and told us that we need to go back to water 2 days a week, bypassing all of the great software Rachio offers… but they leave a door open. That is if we can tie a soil sensor to the system, then we can use Rachio anytime. I am not ready to go back to the simple watering method because it’s just wasting water to satisfy a bureaucratic law. There is so much runoffs from our neighborhood, and I don’t want to be another contributor to this nonsense.
I am not sure where this effort is with Rachio R&D team for cloud-to-cloud sensor feature. From the previous thread, it seems that some may have found a solution to tie in a soil sensor. I am investigating and working with a local soil testing company on this topic. I will share with everyone what I find, if any. In the meantime, if anyone has been successful with this, I would love to hear your feedback. Thank you.
