Deuta Controls Enosense People Counter transmits messages over the EnOcean network. To install the sensor through Map Editor, you need to input the EnOcean Unique Radio Identifier (EURID) as a Serial number of the sensor.
In the case of the Enosense People Counter sensor, this EURID is written on the device.
In this particular case, the EURID of the sensor is 0x042103FE. However, the symbols "0x" are unnecessary, so the correct value to input to the Map Editor is 042103FE.
