Zhaga nodes in the Mediterranean for remote control of radio frequency lighting points

Nea Smyrnī is a small town in the southern Attica region of Greece, more precisely south of the suburbs of Athens, of about 74,000 residents.

In 2021, Revetec started an energy efficiency project for the lighting park, installing devices for remote control of switchboard parameters on ten switchboards and equipping 3,391 lighting points with radio frequency point-to-point remote control.

DIM modules were placed in the switchboards to enable the lines to be forced, the status of the circuit breakers to be known, and the system to be switched on and off using the built-in astronomical clock. The Zhaga node was installed on each luminaire to carry out point-to-point remote control via radio waves. The LPM gateway installed on board the switchboard sends remote control commands to the 3,391 nodes via the LPM/R radio transmitter.

The monitoring of the devices in the field is made available by Maestro web software, installed in the control centre of the municipality of Nea Smyrnī.

The Hyperdroid census APP allowed for a quick and accurate commissioning of the remote control nodes on board each lamp by sharing the geographical coordinates and master data of the GPS-equipped device. In this way, the data was automatically entered into the Maestro web platform.
