SmartHome detectors and sensors are designed both for connection to central units and for stand-alone use without them. These are, for example, motion sensors, smoke, gas or CO detectors or anti-flood detectors. All the sensors work with smartphones, so you always have a full overview of what's going on in your home.

Installing a SmartHome system is easy
The installation of various detectors and sensors is user-friendly and does not require any construction modifications or complicated wiring, as these expansion modules communicate wirelessly.
Pay attention to compatibility
When choosing expansion modules, it is important to focus on the communication protocol.
Some accessories require a connection to the central unit. The purchased module must be built on the same communication protocol as this unit, such as ZigBee or Z-Wave. Otherwise, the two devices will not communicate.
Other devices work independently, for example via Bluetooth or Apple HomeKit. They can be controlled via the manufacturer's app and don't require
a central unit to work.
SmartHome detectors and sensors have many uses
There are a number of detectors and sensors on the market, so we sort them into groups for better clarity.
Motion detectors
Motion detectors for windows or doors
Smoke, gas or carbon monoxide detectors
Vibration detectors
Flood detectors
