Enhance your environmental monitoring with RuuviTag Bluetooth sensors—compact, open-source devices that track temperature, humidity, barometric pressure, and motion. Choose from the 4-in-1 standard model or the rugged Pro series (fully waterproof or humidity-resistant) depending on your storage, marine, or outdoor needs. Easy to deploy and battery-powered (12–24 months per CR2477 coin battery), these tags connect to your phone via Bluetooth—and with a Ruuvi Gateway, extend your reach and send live sensor data remotely to Victron Cerbo GX, VRM, or the Ruuvi Cloud for real-time alerts and trends.
