The doorbell transformers in the UK/EU are different from those in the US. It usually provides 8V/12V/24V voltage output. The eufy wired video doorbell can work with 16V- 24V output.

You have two choices to power your eufy wired doorbell:

• Use existing wiring and transformers
• Use the provided power adapter (How to Hardwire Your eufy Wired Doorbell without Existing Wires)

Use Existing Wiring and Transformers

Follow the instruction on the doorbell transformer to connect the doorbell to the 24V output terminals. If your transformer cannot provide 24V voltage, please upgrade your transformer. Here is the recommended third-party compatible transformer.

UK: VEMER 230V/12-24V transformer

DE: Navaris 220 - 240V/8-24V transformer

Note:

1. The eufy wired doorbell doesn’t work with the original doorbell chime.

2. The original doorbell chime wiring diagrams vary in every house. At the current stage, we would recommend you disconnect and bypass the original chime completely. There is no need to use the jumper on the chime.
