Video Doorbell V2 Unstable Signal

I would do that to see if you can rule out power as a possible contributor to this problem for a couple of reasons:

  1. I don’t believe Wyze Support ever asked me about this when I went through troubleshooting with them after developing chime problems with my Video Doorbell v2. They replaced my Video Doorbell v2, but then I did some additional independent troubleshooting that revealed my home’s built-in mechanical chime had been wired incorrectly before I moved into this house: The wire from the transformer had originally been connected to my chime’s FRONT terminal, and the wire from the doorbell button location was connected to the chime’s TRANS terminal. That difference is practically irrelevant when a simple “dumb” doorbell button is being used, but when you install Video Doorbell v2 and Chime Controller into the system, it’s important to have all the connections be accurate and correct.
  2. I’ve seen some Forum users report performance problems with their Wyze video doorbells and then later discover that they’re using an under-powered transformer (like 10 V AC, 5 VA).

Thanks for checking! :+1:

That seems low to me, and it’s at the low end of what Wyze recommends:

Wyze Video Doorbell v2 has a minimum requirement of a 16V 10VA transformer, but this is at the lower boundary of the power supply spectrum.

I’ll rephrase one of my original thoughts: What is the rated output of the doorbell transformer you’re currently using? If you can find the transformer, then this information should be stamped or embossed somewhere on the transformer’s housing. As a point of comparison, my transformer is rated 16 V, 10 VA, and I have consistently seen in excess of 18 V AC when measuring with a digital multimeter at both the transformer and the doorbell button’s wiring location.

At this point I’m wondering if you should replace the transformer, but before doing that I’d want to know if the transformer you have is supposed to be compatible (i.e., meet the minimum specs Wyze advises) and if it’s correctly wired to the chime (i.e., the FRONT [or whichever] and TRANS terminals had the correct wires in place before you started).
