I'm looking for a existing ZWave Soil Moisture solution to control my drip irrigation for the plantings in front of the house. My drip system has a ZWave Aeon Labs On/Off Relay to control a solenoid that opens the drip feed on a scheduled basis but I'd like to have a way to run it only if there is no enough moisture.
There doesn't appear to be an off-the-shelf ZWave device so I was thinking about a flood/moisture sensor. I have an Everspring Flood Sensor in the Air Conditioner drain line to detect if it gets clogged and the condensation runoff backs up. But i don't know if these devices will work with less than truly wet conditions, ie. moist soil. And is there a way to adjust them up/down or are the simply all-or-nothing devices.
Has anyone tried this and can offer some advice. At present I'm thinking about cobbling together an Arduino solution but i'd rather have a straight ZWave solution.
