The operating distance for connected objects depends on the communication protocol of the object!
If you do not know the communication protocol of your object, check the article: Communication protocol for Enki compatible objects.
Beware, the distances indicated are provided for information purposes only.
Everything also depends on your accommodation... load-bearing walls and pipes may weaken the signal
Enocean : 20 to 30 m (compared to the Enki box)
Zigbee : 10 to 20 m (compared to the Enki box)
DiO 433 MHz : 50 m in open field (compared to the Enki box)
Wi-Fi : 15 to 20 m (compared to the internet box)
Bluetooth : 10 to 15 m (compared to the equipment used to control it)
Note : With regard to the NodOn socket with consumption measurement, what you need to know is that the socket antenna works if a product is plugged into it. In fact, the cable of the device connected to the socket is used to tune the antenna. Thus, it is very important to plug an object into the socket to avoid the range problems that you may encounter with the NodOn consumption measurement socket.
