Aqara Door and Window Sensor P2

Aqara has taken a big step into the future with its latest sensor, the Door and Window Sensor P2, which has full support for Matter via the Thread protocol. The most exciting thing about this sensor is that it does not require a separate hub to operate. Instead, it can be easily connected directly to your smart home and take advantage of devices like the AppleTV or HomePod as a border router to establish a stable and reliable connection.

When it comes to the sensor size, we can note that it is slightly larger than some other sensors on the market. This can be an important aspect to consider depending on where you plan to place it. However, it is worth mentioning that the Door and Window Sensor P2 compensates for its size with an impressively fast response time, which is crucial to ensure fast and reliable detection of door and window openings.

It is important to note that at this time the Door and Window Sensor P2 is not compatible with Aqara's own app. This could be a transition period where users may need to use other platforms or apps to take advantage of the sensor's capabilities. However, it is possible that future updates may change this situation, so it is something to keep an eye on.

In summary, Aqara's Door and Window Sensor P2 is a promising sensor that takes us into the future through its full support for Matter over Thread. It impresses with its easy connection to your smart home and fast response time, although its slightly larger size may be a preponderant factor. While it is currently not compatible with Aqara's own app, future updates could resolve this and give users even more flexibility and control over their smart homes.

Shelly Door/Window 2

Shelly are well known for manufacturing affordable devices that primarily use Wi-Fi technology. Their latest magnetic sensor is no exception when it comes to offering cost-effective solutions. This sensor impresses with its fast reaction time and sends signals in the blink of an eye, and according to the company themselves, it is even “Lightning fixed”.

While Shelly's own app may be in need of a design update, it compensates with reliable performance. The sensor delivers in terms of function and fulfills its main tasks without any problems. It's worth mentioning that one of the challenges with battery-powered devices that use Wi-Fi is that they tend to drain their batteries fairly quickly. This is something that users should be aware of and consider when choosing such a device.

In summary, Shelly's magnetic sensor is a fully acceptable product. If you are looking for a magnetic sensor that is connected via Wi-Fi and are satisfied with the fast reaction time, this may be the right choice for you. Shelly has built a reputation for reliable and affordable products, and this sensor is no exception. So if Wi-Fi is what you seek, you can confidently consider Shelly's magnetic sensor to suit your needs.
