What is eRrigatoreRrigator is what it sounds like. It’s an internet connected irrigation controller. HW costs are less than $40 and probably could be pushed down to about $30. It supports up to 6 stations, but more can be added easily if need be. Programming is different than most irrigation controllers. It allows for multiple programs to be set for each station separately from the others. This means that programming it does not require artificial linkage between different stations.
The unit has its own Real Time Clock (RTC) and stores the programming and configuration on FLASH memory. This means that even without internet connection, it will execute the schedule as planned.
