🔥Fabian Bräunlein and Luca Melette, security researchers, have recently unveiled their research on European streetlights and power plants, which utilize the radio ripple control system developed by EFR.

Their findings indicate that EFR systems employ an 💣 unencrypted RF 🚨 protocol to transmit control commands via longwave radio to a multitude of devices, including relays in solar/wind plants, heat pumps, and streetlights.

🔥Upon being notified of these research findings, the company responded by threatening the researchers with legal action; however, 🐉the research has since been published.
