I watched the installation video and there are no instructions on how to rewire an existing 3-wire system. I have a front door chime sound and a rear chime sound. On my existing unit there are 3-wires, red, white, and blue. How do I configure the new set-up???
Could you take a picture of your chime box? Are replacing the front and back with Wyze doorbells?
You’ll need to bypass the existing chime(s) for the Wyze doorbell to work.
I’m only having the front door active. Photo attached of existing 3-wires. image|666x500
Do you have a photo of inside your chime box?
I solved the problem by process of elimination. I took off one wire at a time to find the correct “two” for the front door. It’s working very nicely now.
