Lightweight and affordable indoor climate sensor The original RuuviTag 4-in-1 packs reliable tracking for temperature, humidity, air pressure, and motion into a compact, open-case design. Best suited for indoor and dry applications where exposure to moisture is minimal. Great for basic cabin monitoring, RV interiors, or indoor labs. It broadcasts over Bluetooth with no pairing, so a Victron Cerbo GX or other GX device reads its temperature and humidity directly, and it also works with the free Ruuvi Station app, the Ruuvi Gateway, and Home Assistant.
