I have over 50 of these devices all working perfectly with the Kasa App and Apple Homekit (with Siri).  I recently upgraded my router which caused all of the plugs to get new IP addresses.  Everything still works in the Kasa App but everything in Apple world is broken.

Is there anyway to resolve this without removing the devices from Kasa App and resetting each device and then reinstalling so that Apple can see the devices again.

Doing this on over 50 devices is going to be painful.

I have already tried resetting the router and the active home hub devices (Apple TVs).

Hoping there is a way to resync the devices on the Apple side so that the new IP addresses are recognized.

Any help is appreciated.
