Google Nest 2nd Gen Wired to Honeywell Home DW915S. I am not an electrician, but thought this info was a little hard to find. I basically used the Honeywell wired diagram with a small twist. I sent 12v to the Honeywell and 24v (see end of video) to the Google doorbell. This was a Series 9 Honeywell, which can be wired or wireless, but I think this would work with almost all types of doorbells. Now to set up the Google Hub and cameras for a complete Google Home and Google Nest Aware set up!
