I'm having the same problems as thsi thread from last year: https://community.tp-link.com/us/smart-home/forum/topic/692096

And I see so many posts on the Internet where people have this same issue trying to pair the KD110C Kasa Doorbell chime.

My chime is green, but I cannot use either the Kasa or Tapo apps to find and link this chime!

Anh ideas on how to get this to work?
