A:Answer I bought it to use with our filter pump for our above ground pool too, but it doesn’t work like I wanted it to. Was hoping to be able to switch it on/off on demand, but once it switches off by timer or manually from the Kasa app, the GFCI built into the pump’s plug trips. In order for it to turn back on, the plug needs to be reset by hand - which defeats the whole purpose of the smart plug. I decided to keep mine for Christmas lights or other uses because it’s still a neat device.
