Rachio is absolute garbage! It’s a smart controller that is useless if you have more than one valve set. If you install two Rachio units they don’t function as one unit. They are connected units that are not aware of each other to deconflict their individual schedules to preserve water pressure and instead function as separate units making scheduling a nightmare. I’ve switched to OpenSprinkler as a result. No wifi issues, smaller units, multiple units can function as one integrated system and they’re cheaper.
