Try adding the switches IP address as the DMZ to test to see if the router firewall may be blocking it from communicating to the cloud. Switch off the DMZ after testing.

Same problem here. Troubleshooting got me nowhere.

Only thing I didn't try was disabling firewall/changing DNS settings on my router because Comcast/Xfinity doesn't seem to let users do that anymore on their recent gateways.

Hello,

 

I got my switch, installed it, connected it to the app, added the skill in Alexa and all works fine from the Kasa app, but it would not be discovered by Alexa, I then located the Remote Control toggle and tried it but it will not turn on, it tells me Failed: Invalid Device.

 

And all things are on the same 2.4 wifi router.

 

I tried to reset everything, uninstall everything, and reinstall. Nothing seems to work.

 

Does anyone have any suggestions

 

Thanks for you help

@brucery I have also been having the same issue just installed my switch today a I have gotten the same invalid device error ever time no matter what I tried. Someone please help this is very annoying.

Hello,

I installed two HS 200's today and received the same response "invalid device" when I attempted to turn on remote access , the switch was grayed out, I have 7 other Kasa plugs and switches and have never experienced this issue before. 
I did all the all the suggested fixes, resetting, then did the full factory reset again nothing. So currently the two new switches are local access only.

Not sure what I should try next.

I am having the same issue.  I have provided the switch with a static IP address and have also tried different WiFi channels.  Nothing seems to work.

@DAHV87 

I will be requesting a refund on this faulty device.

@DAHV87 

I'd say my next question is does TP Link/Kasa monitor this forum for comments and current open issues?  Seems no at this point.  I have seven other Kasa plugs and switches most over 3 years old working flawlessly. The two I received this week appear to be defective and can only connect locally the remote option is grayed out as an unavailable option. If TP Link/Kasa doesn't respond in 48 hours with an RCA or a MTR mine will be returned to Amazon with a 1 star unsatisfactory rating.

@Kemlyn1 exactly the same issue. Anyone get this resolved yet? Tech support was not helpful.

@DAHV87 same thing for me. I'm pretty tech savvy. I have forty or so of the devices that work flawlessly. I have tried everything with no luck. I have noticed the firmware version for the switches that I just installed is different than the others. They actually have a higher number on the firmware version which makes me wonder if Amazon shipped some old switches with old software and kasa isn't updating this version for some reason.

Anyways, enough of my ramblings. Did you or anyone else figure this out yet?

@JasonColorado I have the same problem with a new switch.  I have 14 other HS200 v2s that are all working flawless.

The new switch is a V3 hardware 1.1.3 firmware switch however.  The realy old thing is that one I purchased about 6 weeks ago is the same version of hardware and firmware and that one has been working flawless.  When I go into settings for that one, or any of the V2 hardware switches, it doesn't give me an option to turn on remote control.  It's only the newest switch.  

Appears they changed something that only effects them when they are initially setup.  I'm not going to reset the older working V3 device to test that theory however
