So I recently ordered 16 of the Kasa Smart Wi-Fi Plug Slim Energy Monitoring - EP25P4 (US) Ver: 1.6.  I am having a HECK of a time trying to get them setup.

Router Information

• Archer AX6000 v1.0 - Firmware Version 1.2.4 Build 20210719 rel. 12163(5553)

KASA App Information

• Kasa Smart 3.1.5

Smart Plug MAC

• 30-DE-4B-77-3A-9A

I cannot get the plugs to join to my network. Here are the things I have tried.  (After each change I tried to the setup again, both from the Kasa app and the Home Kit app on my iPhone)

• Reset the plug
• Changed my 2.4 network to be on a static channel (channel 11)
• Attempted to join in the same room as my router
• Turned off my wireless 5 network all together
• Tried selecting the devices wireless and click on add to Home kit from there.

Nothing I have tried seems to work.  When I go to add the device I do the following

• unplug and plug it back in (I know that pairing mode times out after 10 minutes). 
• I reset the plug. 
• I try to add it from both the Home Kit and the Kasa app. 
• I go through the steps and it tries to add the plug.
• My phone sits on the "Connecting to Outlet" screen
  • Sometimes I get the error  "Unable to add accessory.  Operation timed out."
  • Sometimes at the beginning it will say"Uncertified Accessory.  This accessory has not been certified to work with your home and may not work reliably or securely with this iPhone"

I honesty just want this to work with my Alexa, but it appears to force you to use Home Kit, which is fine if that would actually work.

Are there any other tricks I can try, it doesn't seem like it should be this difficult.  I have tried every plug in the first 4 pack I received, they all have the same result.  My house has numerous other "smart plugs" that I was looking to replace with these energy monitoring ones.  Hoping there's something that can get them working before they are headed back to the store to be returned.
