Review: Great for smart doorbell! - I bought this because I wanted a doorbell with a built in transformer with the enough power to hardwire my smart doorbell (Eufy E340). Most of the other doorbells I looked at either didn't have the required output, didn't state what the output was or required buying an external transformer. This one looks great, was very easy to install - it replaced a Deta model, so it was just a matter of fixing it to the wall and and swapping the wires over. It has a proper traditional DING-DONG which works reliably with the Eufy. A big thank you to Scoutsiraj for their review on here and confirming that it works with the E340. Review: Chime doorbell ORNO - The product arrived slightly damaged, but this didn't affect its performance. Overall, I'm satisfied , good price and looks solid. Arrived on time, even a day early. I recommend the product and the seller. My only suggestion is to pack it with more bubble wrap. ## Features - ✔️ 230V AC POWER SUPPLY WITH INTEGRATED TRANSFORMER - The unit is powered by a standard 230V installation and features a built-in 8V AC transformer that allows you to securely connect the doorbell button - ✔️ SHORT BUTTON PRESS - To get the correct two-tone ringtone, briefly press the button - ✔️ Classic Dual Tone - The mechanical dual tone doorbell has a volume of 80dBd.

My only suggestion is to pack it with more bubble wrap. ### ⭐⭐⭐⭐⭐ Works well with smart Doorbells *by S***J on 26 February 2025* This Doorbell gives the perfect solution to smart doorbells issues. After hours of research to find a suitable doorbell that works with Eufy E340 Video Doorbell. I tried this door bell and it works perfectly without needing any additional transformers. It takes input voltage of 220-240VAC (so no transformer required at the fuse board) and gives an output of 8-10VAC (although listing states 8VAC) and resolves two problems: 1. It charges the Eufy E340 although Eufy state you need a voltage supply of 16-24VAC (so it might work well with other smart doorbells). 2. My old doorbell used to only work on the first button press, now no matter how many times you press the smart doorbell button it rings.
