A report, full of proud words, found on LoRa Alliance site:
And the same story on manufacturer's site:
"In this first stage of the project, inteliLIGHT® LoRa™ controllers were installed in 4 of the 19 feeder pillars in Szada."
4 (FOUR) devices. Not too much.
Think we may say that it seems it's too early to use LoRaWAN for street lights
