Nest Hello UK Install With Integrated Transformer
Intro: Nest Hello UK Install With Integrated Transformer
Anyone finding this post knows that installing a Nest hello doorbell in the UK is far more complex than it should be, so I decided to post my set up.
Inspired by numerous others who had either hacked a mains powered transformer or used a separate transformer housing. Note I'm not a professional, just a DIYer who likes to give things a go!
I'd seen a comment in Madargy's post (referenced below) that the transformer in question wasn't designed to be always on. So I thought I'd come up with my own hack.
My main objective was I wanted one integrated box. Had seen numerous install vids and guides online, and all had a seperate transformer, I didn't like the look of that.
STEP 1: Prepped the Project Box
Drilled holes in the sides of the project box to allow the chime to sound through. And drilled holes in the back where I would drill the box onto the wall. Those holes were aligned with existing holes in the chime. I.e. I planned to screw through the chime, via the project box, onto the wall.
STEP 2: Prepped the Chime
STEP 3: Wiring
Wired the mains power into the transformer and then the transformer and bell cable to the nest adaptor and chime. Followed the attached wiring diagram.
STEP 4: Wired Up the Nest
Turned on the mains and Tested the whole system and set up the Nest. Switched off the power again and then proceeded to finalise the fittings, screwing the Nest and the project box onto the wall.

Could you tell me exactly which size project box you got please?
Also, did you choose this mechanical chime because it will cope with 12va (rather than the 8va that it is boxed with) better than an electronic chime would?

I didn't even consider an electronic chime to be honest, prefer a traditional sound.
