I recently bought a bunch of different Kasa smart switches for my home. 

Most set up ok but a few, namely the single pole switches, the LED remains RED/Orange when they are not able to reach the internet.

I have purposly configured these on a network without internet access since I control them separatly. Is there a way to return the LED to its original function without cloud access?

I have seen a few threads over the years mention it but non really had a solution other than to connect them to the internet.
