Slovensky (EUR)Door and window sensors are among the simplest elements of today’s smart home. Their price is in the range of a few hundred crowns, and they do more than a good job. This basic element can help secure your home and keep track of every door or window. Thanks to their easy installation and simple connection to your app, we recommend sensors as part of the initial equipment for your home or business. There are already several different types and designs on the market, and some even offer additional features.
Let’s briefly describe selected types:
Aqara MCCGQ11LM is a compact wireless Zigbee door and window sensor that detects opening or closing via a magnetic contact. It is known for its reliability, fast response, and long battery life (up to 2 years on a single CR1632). The sensor is compatible with Aqara, HomeKit, and Home Assistant platforms (via Zigbee2MQTT or ZHA). Thanks to its small size, it is unobtrusive and easy to install using a sticker. It is suitable for smart home automation and basic window and door security.
Moes ZSS-GWM-C is a compact wireless Zigbee 3.0 sensor that instantly detects opening or closing and sends real-time notifications to the Tuya Smart, Smart Life, or HomeAssistant mobile app. It requires a Zigbee hub to operate. The sensor is powered by a CR2032 battery lasting up to 2 years, has an attractive design, and supports integration with Google Assistant and Amazon Alexa for smart home automation. Installation is easy, and the device is suitable for securing an apartment, house, or office.

Detailed comparison and experience
Aqara MCCGQ11LM
Pros
- Long-term proven and reliable sensor with very compact dimensions.
- Battery life often exceeds 2 years
- Integrated temperature and outage sensor
- Instant response when opening/closing (suitable for light automation, etc.) and very high-quality workmanship.
- Spare set of adhesive pads included
Cons
- Uses a less common CR1632 battery and older Zigbee version, which may mean worse compatibility in some networks, especially with a larger number of devices.
- Unnecessarily large packaging, which is at least 3x larger than the second largest, and up to 7x larger than the smallest.
Moes ZSS-GWM-C
Pros
- Uses a standard CR2032 button battery
- Detection distance around 20 mm.
- Offers basic features, including low battery warning.
- Suitable for universal Zigbee networks where price and availability are a priority.
- Nice design and small size
Cons
- In Zigbee2MQTT it appears to have a tamper sensor, but physically it is not present.
Sonoff SNZB-04
Pros
- Easy integration into various Zigbee ecosystems (Home Assistant, Zigbee2MQTT)
- Low price
Cons
- Slightly longer response time when opening (about 1 second), which can be a disadvantage for automations requiring instant reaction.
- Occasional disconnection issues, but most users still rate it as reliable.
- Rather large and boxy design
Sonoff SNZB-04P
Pros
- Thanks to the larger battery (CR2477), it lasts up to 5 years.

Final evaluation
Each of the selected sensors has its purpose; when choosing, at least one important parameter will always be decisive-price, size, or available features. If you are looking for a small capable sensor at a good price, Moes or Aubess is a good choice. If you require more features and quality and don't mind paying extra, then Sonoff SNZB-04P or Aqara is the clear option. However, all sensors perform their function flawlessly, all types have been tested long-term, and so far there have been no issues with functionality. Battery life, of course, depends a lot on usage-how often the sensor changes state and where it is placed.
