I’m looking for a way to monitor sump pumps running. I know that I could use something like the Iris smart plug but I have two issues with that:
I don’t need the sophisticated power monitoring. I only care if the pump is running; not power consumption.
Having a switch just introduces a way to accidentally disable the pump. I absolutely hate the idea of any switching capability. It just invites disaster.
In the case of a column pump, I could tap into its wiring after the float switch. But in another place I have a submersible pump and the monitor would have to be at the plug.
