@coslor @franz - i do not agree that using any weather history for forecasting what is going to happen today, tomorrow or 10 days from now when determining irrigation needs. The reasons I don't agree are, a) we are going through a cycle of climate change. What is happening today is not likely what has happened in the past, b) many of us either live in micro-climates, affected by geography or, sometimes mother nature doesn't do exactly what forecasters think she's going to do.
I have reported before that I've seen my schedule being skipped because your source of weather has overstated what is going to occur or missed it altogether. This has happened to me again this weekend in a dramatic way, causing me to manually water my turf.
To be honest, there certainly are opportunities to determine when and how much to water. Many of those capabilities exist today without cloud services, such as through Hunter systems and their sensors. I've owned one for the last 15 years. They aren't perfect but they make decisions on what happened at my location in the recent 24 hours or is currently happening and adjusts accordingly. Cloud services (such as the Iro) should offer us a more granular approach to 'now casting'. Right now, it has taken me back several years and forcing me to spend more time managing my irrigation on a daily basis. This is exactly what I don't want to do.
The biggest benefit I'm enjoying from this system at the moment is the iOS based remote control, something that was costly to achieve with the Hunter system. I am hopeful that Rachio's roadmap will get us to a more intelligent, more dynamic, more localized management capability in the near future.
