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.

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!
All devices are required to meet UL943. Class B or C devices are obsolete and not used. Has nothing to do with operation of the switch.

The KS220 works with the standard GFCI circuit. Do you encounter any problems with the device installation? Please share more detailed information here so that we can try to assist.

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 doing the job it was designed to.
Your ENG department should be able to reproduce this issue and verify. The model HS103 and KL135 seem to work.
The KASA model KS220 does not work with a GFIC. it was mentioned in the reponse that my GFI may not be standard.
The GFIC used is a UL certified device and manufactured to meet UL493, CLASS A. 4mA, MAX.
It was also mentioned that my GFIC may not be standard.
FYI: GFIC, CLASS B, is obsolete and not able to buy, and not carried by electrical supply house, or very difficult to buy, and that class device allowed 20mA to flow to ground.
The ground wire offers additional path for the electrical current to flow into earth so as to not endanger anyone working with electricity nearby in the event of a short circuit. Without a ground wire, your body could instead complete the ground path and may cause shock or electrocution.
This device was drawing over the 4 mA, and tripping the circuit. This is not acceptable.
This device is not safe for use near a damp or wet area. Use of this device with out a GFIC circuit

Can you provide the brand and model of the GFCI you used? What's the type of it (wall receptacle, circuit breaker, and portable plug-in)?

TP-Link has replied. Their Smart switches are not approved for circuit that requiring GFIC protection. They should not be used in a bathroom or a kitchen or a pool light or outside application where exposed to water, because of the electrical hazard they can create. They use the earth ground as a path to complete the circuit operation. You will find that when used with a GFIC circuit that they conduct current thru the eath ground, tripping the GFIC breaker.
Note" please be aware thet smart light bulbs never turn off. They also cunduct power even when off. These devices are know as Vampire Devices.

TP-Link Kasa Switches has done relevant testing with different GFCI and came with positive results. Several tests were done again by the lab after you reported this issue and the problem cannot be reproduced, the KS220 works well with the GFCI and did not trip it.
Device hardware malfunction, wrong wiring, compatibility issues with this specific GFCI or your circuit environment can be the possible causes of this issue you're facing.
Try to test another KS220 if you have or contact TP-Link support to replace it with a new one. The circuit environment of each family or building is different. If possible, try to do the test in another different circuit environment.
