@DOrio Just for the record, The GFIC being used is a Cooper Electric VGF15W-3. 15A-125V AC. Meets the UL943. " WHICH IS THE CODE IN THE USA!

Can anyone say they used a smart switch with a GFIC

@Wayne-TP Yes KASA ENG. support has responded, and advised to use DEVICES, HS103, OR KL135. YES, I was able to reproduce the failure, and measure the current. The GFIC used is working correctly and...

If the switch is flipping the GFIC off the switch is bad, Period! That's all there is to it. There should never be a condition where current is conducting to ground. The device is bad. Replace it!...

Does the KASA KS220 work with a GFIC circuit. Has anyone reponded TP-LINK or had this issue been resolved? I am not finding anything, and it's been some time now. Switch is wired corrcetly.
