Wyze Doorbell v2 Chime Issues

I concur with @fmills1d that the wiring appears correct but would stipulate if the correct wire is going to the middle “T” terminal. I say this because of my own experience with Video Doorbell v2 and troubleshooting that revealed that my chime had been wired incorrectly for years prior to my doorbell camera installation.

A few thoughts:

  1. If you have a way to test the wiring and confirm that the correct wire with power from the transformer is actually going to the “T” terminal, then I’d definitely do that. In your photo, it looks like you have terminals for “R”, “T”, and “F” (top to bottom), so the Chime Controller does appear to be wired correctly if the black wires coming into the chime box are what you think they are.
  2. If you don’t have a way to test the AC voltage, then you could try swapping the black wires that are coming into the chime box:
    a. Disconnect the black wire from the T-terminal.
    b. Remove the wire nut from the other black wire and Chime Controller black wire.
    c. Use the wire nut to connect the first black wire (that you just removed from the T-terminal) to the Chime Contrtoller’s black wire.
    d. Connect the remaining wire to the T-terminal (along with the Chime Controller red wire that’s already there).
    That may not have any discernible effect, though, and even if it works it might not be a permanent solution. (My Video Doorbell v2 worked for months with the wrong wire connected to the TRANS terminal on my mechanical chime…until it didn’t.)
  3. You could also try the alternate wiring method, though I’ve been advised by Wyze Support “that the buzzing/clicking sound on the chime is normal when an alternative wiring method is used.” That wasn’t acceptable to me and is what led to my additional troubleshooting and discovery of my wiring problem.
  4. What do you have selected for Doorbell Chime Type? If it’s set to Mechanical, then you could try Digital with a Ring tone length setting as specified in another Help Center article.
  5. You’re probably already doing this and have the Chime Controller moved for the sake of the photo, but you want to be sure that the Chime Controller and wiring aren’t touching or interfering in any way with the tone bars at the top and bottom of your chime. That kind of interference could cause a muting effect to the chime sound.
  6. If you’re checking on your transformer rating, what you want to look at is its voltage (expressed as “V” or “V AC” or “VAC”) and apparent power in volt-amperes (expresesd as “VA”). The former should be in the 16-24 V range, and the latter should be ≥10 VA.
