For reference, the Video Doorbell Wired requires a transformer that is rated 8-24 VAC, 10-40VA, 50/60Hz. As per printed specs on its downside it accepts 8-12V AC, and sure enough inside there's the very simple solenoid magnet pulling a small plunger against the outside metal cup. Our power supply meets the stringent Efficiency Level VI standards, ensuring that it’s powerful and environmentally friendly. The upshot is that you've created a "mechanical switching" inverter supply and the output of the transformer will be a useful AC voltage. This thread contains some great discussion regarding different installation methods for the Video Doorbell Wired based on what transformer you may have or want.

Aside from snubbing, they may also have an impact on the frequency and robust behavior (or lack of it) of the overall circuit. Classic Doorbell, 9m bell wire, 8 Volt 1 Amp transformer 7960 Brass bell push, fixing pack and instruction manual.This power supply boasts a single fixed output, which means it’s purpose-built to meet the specific requirements of your Aqara Smart Video Doorbell G4. This topic has been useful to help me choose a new, compatible transformer after determining that the existing transformer used to power the old chime and doorbell didn’t work with the Ring Video Doorbell wired. Low Voltage Power Supply, AC to DC Adapter, Constant Voltage for LED Strip Lights and Cabinet Lights, LED Bulbs, Ring Doorbell. But it has the advantage that you don't have to be a mathematical genius to tinker with it until you get what you need.

It looks like the 4 core cable could have been there to supply an illuminated bell push, but has been configured to be just two wires. When you add the transformer, uncover the relay, turn out the lights, and you may see small sparks fly across the moving contacts. It provides a stable 12V DC output with an impressive 1A current rating, ensuring optimal performance.

I’m doing some IT upgrade stuff this week and all weekend, so I won’t be able to do it until next week. I happened to have a suitable illuminated door bell button which could also powered from the 12v DC PSU, however be aware that some standard illuminated buttons may not work as they work with specific door bell kits. The Video Doorbell 3 requires a standard doorbell system with 8-24VAC doorbell transformer if you plan to hardwire it.

I've tried to check the voltage available at the button using a multimeter across the terminal screws.Bell transformers are not able to supply much current, your 'automotive bulb', unless it was a very small one, might have tried to draw more than it was capable of supplying - hence no light.
