Follow-up question. Are all the models Gen1/2/3 work offline (no wifi) access?
For example, if we (or in between tenants) do not have internet service for a while, will the controller still water based on the programming schedule without an internet connection - similar to how a traditional controller works? Or, do I have to manually start the controller every time/day?
I have not had this kind of experience, but my understanding is that they will continue to work without Wi-Fi. Here is one example, look under heading " What happens if I lose Wi-Fi?" on (Rachio Generation 2 FAQ)
