I would like to monitor the water level of my rain barrel. What I would like to do is set a schedule to run a pump that I have, but ONLY if there is water in the barrel obviously. So when the water level gets to a low level the pump turns off. I was thinking of a water sensor that is on a wire, and then when the sensor reads DRY, I will make a rule that will stop the pump?
has anyone tried this, or is there some kind of Z-Wave/Zigbee float level sensor?
