Do you like smart accessories for your home? Then you definitely shouldn't miss the Zigbee ZB3 smart door sensor, which you can find in the T-LED store . It recently arrived at our editorial office for testing, and since I've already successfully tested it, it's time to introduce you to the results. So let's get started.
Technical specifications, processing and design
The principle of the Zigbee ZB3 door sensor is absolutely simple in its essence. The sensor consists of two magnetic parts that "know" whether they are connected or disconnected and everything works based on this. So as soon as these parts are disconnected by opening windows, doors or anything else, you will receive a notification on your phone or smart watch about the disconnection or, conversely, the connection.
The sensor is powered by a CR2032 battery, with the dimensions of the larger part being 55 x 25 x 13 mm, and the smaller part being 35 x 11 x 23 mm. The Zigbee 3.0 standard takes care of communication, but for the sensor to work, you need a bridge - in my case it was a Zigbee Gateway G2 , because unfortunately the device does not understand the Philips Hue Bridge. This is the only major stumbling block for me, because if you have a lot of accessories connected to the Hue Bridge, it would definitely be nice to be able to use it in combination with this sensor.

As for the workmanship and design, I dare say that the manufacturer has done a really good job, as this is a very nicely made piece for the home. The device is small, inconspicuous and, thanks to the use of white plastic, has a pleasant overall design and miniAnd given that this is a purely interior solution, it is probably not surprising that "only" IP20 protection is sufficient here.
The price of the Zigbee ZB3 smart door sensor is set at CZK 280 at the time of writing the review, which I dare say is a really tempting offer.
Testing
The first start-up of the sensor takes a matter of a few seconds – that is, if you have a Zigbee Gateway connected to your phone.onem, in my case the Tuya application. If this is the case, all you need to do is start pairing in the application, then remove the plastic battery cover from the sensor and use the included "pin" to activate the pairing process by pressing the internal button. Once you do this, the connection of the sensor with the gateway and therefore the phoneonem will pass in the blink of an eye, and then the real fun begins.

The possibilities of using the sensor are really wide and I dare to say that everyone will find a use for it. The elementary function of this product is, of course, to alert you as soon as a window, door or even a closet opens or closes. Here I will just point out that in order for the sensor to detect everything correctly, it needs to be installed correctly. So, during installation, be careful to stick it as needed, which is also a piece of cake. All you have to do is follow the arrows shown on the sides of the sensor and you're done. From now on, you can receive notifications on your phone or watch about the opening and closing of windows or doors, while the notification options can of course be customized in various ways in the application.
For me personally, however, the main charm of this solution is in the automations that can be created in the application. You can very easily set it up so that when you open the door to the terrace, for example, the light on it will turn on, and as soon as you close the door, the light will turn off. The only thing you need to remember is that the light you will control in this way must be compatible with Tuya and you are done. So, for example, I set it up so that when I open the door to the built-in wardrobe, the LED strip that I had plugged into a smart socket will turn on , and when I close it, the LED strip will turn off again. What I think is absolutely great is the fact that you can also set the time, day, and so on in the application for the automation to be triggered. In short, the possibilities are endless and it is up to you to fine-tune everything to your satisfaction.

Summary
So the Zigbee ZB3 door sensor passed my testing with flying colors. Sure, we can talk about the fact that it lacks support for example HomeKitIt may not work with the Hue Bridge, but it should be taken into account that we are talking about a sensor for less than 300 CZK that works with a clear, reliable application. So I am not afraid to recommend this useful assistant for purchase, because you are able to come up with really interesting things with it.
I used to have it on the doors and, due to the control of the thermal heads, also on the windows, but constantly changing the batteries is not possible
