Ring Retrofit - reconnect after deleting by mistake

My ring retrofit kit has been working great for 3 months or so. Today, I deleted the retrofit device from the app. I am not able to add it back. I have done everything, but the device does not connect back with base station. Is there anything I can do for the base station to start hearing for this retrofit kit. I would hate to remove all legacy wired connections from the retrofit kit / reset basestation etc. to make the basestation start listening for this retrofit kit. I feel like retrofit kit was not deleted properly from base station, so I am not able to add it back.
