Replaced old 1950s receptacle w new one. Added clamp-on current sensors out to a #Zigbee unit in a separate (plastic) box to contact #HomeAssistant.
Broke the tab off to split the receptacle and applied sensors to track dehumidifier and sump pump separately.
Needed a sensor flip to fix current dir, but it works nicely now. I get an email if the pump comes on!
Only in the house 6mo or so, and don't think the sump pump has run yet. We'll see how spring goes – probably the riskiest period.
