Existing transformer for Nest Doorbell (Wired)

schnazzles · 13 Nov 2023

I have an exisxting doorbell transformer fitted (RDL M412) but I can't find anything on the internet about it. Is anyone familiar with this model please? I'll be bypassing the existing chime and just using Google minis for notifications so I just need to wire the doorbell direct to the transformer. Thanks in advance.

You will need to check what secondary voltage is required for your Nest doorbell, and if your existing transformer can match it.

Personally, based on previous dramas with such things, I would buy a compatible Nest transformer as well, and be done with it.
