It uses Bluetooth Low Energy (BLE) on a 2.4 GHz Nordic nRF52832 chip, broadcasting data every 2.5 seconds for multiple receivers. Indoor range is 5-20 meters; outdoor up to 100 meters (optimal 200 meters without obstacles). For extended range or remote access, pair it with the Ruuvi Gateway (up to 2000 meters) to connect to Ruuvi Cloud. It also supports mesh protocols like Wirepas, ANT, and NFC-A for short-range reading (up to 5 cm).
When used with the Victron Cerbo GX range will be less because of the limitations of the Cerbo internal Bluetooth antenna
