Description
Rugged Bluetooth sensor for temperature, humidity, air pressure and motion — made in Finland, and a proven match for Victron GX systems.
The RuuviTag Pro 4-in-1 is the industrial-grade version of the RuuviTag. Its polycarbonate enclosure with breathable membrane is rated IP67, so it lives happily in engine bays, battery boxes, fridges, plant rooms, vans and boats. It broadcasts readings every 2.5 seconds over Bluetooth, logs 10 days of history on board, and runs 12–24 months on a user-replaceable CR2477 battery.
Works with Victron Cerbo GX and VRM
Pair a RuuviTag Pro with any Victron GX device (Cerbo GX, Cerbo-S GX, Ekrano GX, Venus GX) running Venus OS and it appears as a wireless temperature sensor — no cabling, no extra hardware. Readings show on the GX touch screen and in the VRM Portal, where you can graph them and set alarms. Typical uses: battery compartment temperature, fridge and freezer monitoring in campers and boats, engine room heat, and remote cabin or site monitoring alongside your Victron system.
