RuuviTag 4-in-1 Sensor

Know what's going on inside your rig, even when you're not standing in it. The RuuviTag is a small, weatherproof Bluetooth sensor that tracks temperature, humidity, air pressure and motion and sends the readings straight to your phone. Stick one in the fridge, the battery bay, the engine room or the cabin and get an alert the moment something drifts out of range.

Works with your Victron system

RuuviTag connects to Victron GX devices like the Cerbo GX, so its temperature and humidity readings show up right next to your battery and solar data. It also works with Home Assistant and other smart-home platforms.

Why it fits RV and marine life

• 4 sensors in one: temperature, relative humidity, air pressure and a 3-axis motion sensor
• Weatherproof: IP67-rated sealed enclosure for damp spaces, lockers and outdoor mounting
• Remembers while you're away: stores 10 days of history at 5-minute intervals and syncs to the free Ruuvi app when you're back in range
• Custom alerts: set high and low limits and get notified on your phone
• Long battery life: 1–2 years of typical use on a user-replaceable CR2477 coin cell
• Range: roughly 16–330 ft (5–100 m) depending on walls, metal and water. Pair with a Ruuvi Gateway for remote monitoring from anywhere.
• Tiny: 2.05 in (52 mm) across, 0.49 in (12.5 mm) thick, about 0.9 oz (25 g) with battery
