Wiring 2 Unifi G4 doorbells, with official diagram!

Written by Andrew Gioia on October 10, 2020  ·  3 minute read

I was incredibly excited when Ubiquiti announced the G4 Doorbell in their Unifi Protect line earlier this year. I finally got my hands on one last month and installed it, and then immediately (and unsurprisingly) wanted to replace the back doorbell too. Unfortunately two doorbells didn’t appear to be officially supported and given my very basic electrical knowledge, I frustratingly failed while trying to use Nest’s diagram and some advice from the community.
