Power Unit Monitoring


New member
I am looking for some affordable, simple technology that will give me proof of life when operating irrigation power units. Pretty sure I can't afford a full on control solution.

Basically, something that would message or notify me in some way when a murphy shuts down would be great. Seems simple enough, generates radio waves when the power unit is running, as soon as it shuts down, and the wave breaks, it sends a message to me.
