does anyone have an easy, cheap device to control the water flow? I have my garden irrigation with Hunter valves attached to my tank pump running in my HA, but I am afraid of hooking my house water directly to the system. So i thought I set a second, more reliable stop right at the beginning. Any ideas? Has someone the cheap Gardena Bluetooth stop running in their HA? https://www.gardena.com/de/produkte/bewaesserung/bewaesserungssteuerung/bewaesserungssteuerung-bluetooth/970481101.html
