So, my idea here is to set up an automation to turn on a sprinkler zone based on motion. Easy enough using simple motion app. However, I would need to figure up a way to power a sprinkler zone independently of my dumb Rainbird controller. I could easily grab the voltage from the controller power supply but I am having trouble finding a device that can:
- Isolate the the zone wires temporarily from the controller to avoid back feeding voltage into the controller.
- Provide voltage from the power supply to said zone wires during the above condition.
- Easily, well relatively anyway, integrate with Hubitat. I've got strong wifi, zigbee, and Zwave meshes running so I'm open to most any wireless protocol.
- Not cost a fortune(Rachio, etc.)
I'm sure there is some sort of set up out there that can provide this sort of functionality. Any of you gurus out there have an idea?
