If you run an Iro2 exclusively on Flex Daily (fully automatic), then your unit is worthless if you no longer maintain an Internet connection and/or Rachio goes out of business.
I tell all of my friends, colleagues and family members to go buy an Iro2. I want to help sales so that Rachio’s long term existence is assured.
In my case, I run exclusively on Flex Daily, with all days allowed to water except Saturdays. A loss of internet connection will cause my Iro2 to water every day of the week except Sat., a full maximum daily watering every day. Not very useful.
The comment about setting up a cellular based Internet connection is a good one. We (my company) do this for homes and businesses where we want to install Internet connected thermostats, and/or Internet connected monitoring/sampling of energy & temperature, where’s there’s no Internet presence, or, it’s a company with a major firewall that has security concerns with a port we need opened up. There have been plans where there’s no monthly cost - just buy the hardware. The hardware is inexpensive too since data volume is so minimal.
If I ever ‘cut the cable’ at my residence, I’ll simply implement the cellular solution. It will work well for the Iro2, Web Energy Logger (WEL), Network Thermostats tstats, and Rheme gas water heaters - all which have an Internet connection now for automated control. The fire and security system will require some additional thought. I’ll have to return to a POTS connection just for fire and security, or, do it via microwave.
