Method and sources

This prototype performs an exact label lookup. It trims surrounding space and ignores letter case, but it does not remove punctuation, merge similar model names, infer generations, or treat a missing row as incompatible.

Ring: In-home chime kit compatibility list for Wired Doorbell Plus and Pro

Observed 27 September 2026. The page states that its feature applies only in the United States and Canada and publishes compatible/incompatible mechanical and digital chime tables for Wired Doorbell Plus and Wired Doorbell Pro.

Bounded catalog

The prototype transcribes 13 exact maker/model pairs: six single-verdict compatible rows, five single-verdict incompatible rows, and two rows that appear in both verdict sections. Those two conflicts deliberately return UNKNOWN.

The stored source receipt records the exact sections and values used. No copy of the manufacturer page, images, or installation instructions is stored.

Decision rule

  1. Require region, exact doorbell label, maker, and model.
  2. Reject inference outside the cited US/Canada scope or outside the two doorbell labels.
  3. Match maker and model exactly after case and whitespace normalization only.
  4. Return the published verdict only when every observation agrees.
  5. Return UNKNOWN for absent or contradictory rows.
