Review on 💧 Efficient Water Heater Control System for Smart Homes by Grant Galloway

I wanted a pluggable water detector and switch off if possible. I'm not interested in being notified by smartphone. This thing with all these features costs $25. About an hour later I installed the shutdown and control module. That works great. I didn't put the post on either side of the handle, only on the shut down side. I want to be able to move the handle back and forth like before. I can open the valve again when I know everything is ok.
