Finding a compatible chime for your UniFi doorbell can be challenging. Connecting a mechanical or digital chime is possible, but you will need to sort out the correct adapters and wiring schedule. A much easier option is the UniFi Smart Chime.

The UniFi Smart Chime is a wireless connected chime that you can plug into any standard wall outlet. It connects to your UniFi Protect system using your wireless network and is paired with an UniFi Protect Doorbell.

In this short review, we will take a look at the Smart Chime.

UniFi Smart Chime Review

The Smart Chime is obviously a really straightforward and easy-to-use device. It doesn’t come with a lot of options, but it works more than fine. You can use the smart chime throughout your house, all you need is an electrical outlet and decent WiFi coverage.

To use the chime you will need to have an UniFi Protect Doorbell. Good to know is that you can only connect the smart chime to one doorbell. But on the contrary, you can connect multiple Smart Chimes to a single doorbell. This allows you to place a chime in your living room and upstairs as well for example.

The UniFi Smart Chime itself is pretty small in diameter, but it does stick quite a bit out of the socket (5cm / 2″). Furthermore, we will only find 5 white LEDs on the top of the chime, which indicates the WiFi signal strength and is used during the initial setup.

I measured the amount of decibel the chime produced with the current melody. I don’t have a calibrated dB meter, just used my phone from 2 meters distance, to give you an idea. The current melody tops at 71dB and is on average 60dB. The duration of the melody is 3 seconds.

UniFi Smart Chime Setup

Installing the smart chime is really simple. As mentioned, there is not a lot to configure for the device. So to get started all we need to do is plug the chime into an outlet where you have wifi coverage.

When you then open the UniFi Protect console you will get the option to adopt the new device:

During the process, we can select the device to which we want to pair the Smart Chime. The last step is to set the speaker volume and test the chime tone.

You can change the paired doorbell and volume later in the UniFi Protect console:

Wrapping Up

There is still room for improvement when it comes to the Smart Chime. A different melody, the duration of the melody, and maybe even the volume level could be a bit better. But overall it’s a great and simple-to-use product.

Installation is done within a minute and the ability to connect multiple chimes to a single doorbell is great. The ultimate option would be the ability to connect multiple doorbells to a smart chime, each with its own melody. But for most use cases, the current features are more than enough.
