zdravím, ak je to zigbee a nemám ZigBee vysielač, cez wifi klasicky nepôjde?

Keep your home safe with smart devices like the SONOFF SNZB-04P door and window sensor. The sensor can be easily installed on a window or door frame using 3M tape. It consists of two parts, and as soon as the parts are separated, the sensor sends an alert to your mobile phone. You can also connect the sensor to other smart home devices, such as a security camera, via a Zigbee hub. This also allows you to set up automated scenes.
The SONOFF SNZB-04P door or window sensor is powered by a CR2477 battery and communicates using the ZigBee wireless protocol. You can easily synchronise it with your mobile phone, which will send you a notification if a door or window is opened without authorisation and also when the battery needs replacing, which is only about once every 5 years. You will also be informed of any attempt to remove the SONOFF sensor.
Connect the sensor with other elements of your smart home to enable communication between them. This allows you to easily set up smart scenes, for example, turning on a security camera or switching on the lights the moment a window or front door is opened.
