To detect my pool pump I re-wired it to use use 120V and spliced in a Kasa plug – first I spliced in male and female 3 pronged plugs and then stuck the Kasa plug in between 'em. That worked fine and now I can see my pool pump.
Can I do something similar with my split AC?
The split AC runs at 220 on a dual pole 15A breaker. Can I splice in two Kasa plugs, one for each 15A pole, and monitor the split AC that way? I could merge the two Kasa plugs into a single sense device. Will the injection of the Kasa plugs throw off the phases of the two poles so that the AC wont work? Or should it work just fine?
