US based customer here...
I have multiple 3-way switches in my home. I've been waiting on a Tapo solution since Tapo and Kasa aren't interchangable within their apps. I have one significant question...
The wiriing diagrams seems to indicate that only one of the two switches can be replaced with the S515...the other must remain (in my case) the old flip switch. I realize I can replace an old flip switch with a paddle switch, but since it won't match the Tapo look, why bother.
What I want to know is...can both of my flip switches in the 3-way circuit be replaced with the S515? I see the S515D Kit, but I don't need...not do I want...dimming capability in some cases.
Thanks...
In physical wiring, two S515s cannot be used together to function as a 3-way switch. However, you can simulate a three-way switch effect through software feature -- create automation rules.
Actually, the Kasa switch can now be controlled with the Tapo app. Have you tried to link Kasa devices to Tapo? The following articles might help you better understand this integration.

@Wayne-TP Hello.
Have a question regarding the control of the switch.
The post states the following:
"Your connected devices in your local area network (LAN) remain accessible via the Tapo app or other Matter-compatible smart home control centers, even when the household goes offline."
Does this mean that the switch can be used without needing to communicate with or phone home to TP-Link Cloud servers?
I am very interested in a switch that can be used LOCAL ONLY that works with Home Assistant or OpenHAB and does not phone home.
I have read that Tapo switches need a cloud account to set up and have read other places that if they are disconnected from the Internet they stop working.
Please provide clarification.

Local control needs to be conducted through the Tapo app or the corresponding app or software of the Matter platform.
If you're not using Matter and instead connecting devices to third-party platforms through open-source methods, as this isn't an officially supported control method, we cannot guarantee the product's performance.

I have re installed the old dumb switch and it works. Then hooked up the s515 and the gfi trips as soon as the breaker is turned on. I did not push everything into the box just to be sure nothing was touching. Could the s515 generate a signal the gfi doesn't like?

I wired around the GFI and all works fine.

Is everything alright now? What changes did you make?
If the problem persists, I recommend reaching out to the local TP-Link support team for further assistance, and you may want to include some pictures of your wiring, this will be helpful.
