RuuviTag is a compact and versatile wireless sensor that is ideal for monitoring the environment on your boat. Its four built-in sensors measure temperature, humidity, air pressure and movement, giving you complete control over the conditions on your vessel. The sensor sends the data directly to your mobile phone via Bluetooth, and the user-friendly Ruuvi Station app allows you to monitor the measurement values ??in real time, analyze historical graphs and set custom alarms.

RuuviTag is particularly useful in marine environments where accurate monitoring of climate conditions is crucial for comfort, safety and equipment protection. It helps detect critical changes, such as moisture buildup or temperature fluctuations, that can affect sensitive systems on board.

Compatibility with Victron Energy
RuuviTag is fully compatible with Victron Energy systems, making it easy to integrate the sensor into your existing energy management and enabling even better control over your boat's climate.

4 built-in sensors
Temperature measurement: Accurate information on ambient temperature for optimal comfort. (0C, 0F, K; accuracy ±0.2°C between 5-60°C)

Humidity measurement: Monitors humidity and prevents mold and moisture damage. (RH-%, g/m³, dew point; accuracy ±3 RH-% between 20-80%)

Barometric pressure measurement: Helps predict weather changes and understand local weather conditions. (Pa, hPa, mmHg, inHg; accuracy ±1 hPa)

Motion Detection: Records movements and vibrations, making it useful for security and surveillance.

RuuviTag is a wireless sensor that sends measurement data directly to your phone via Bluetooth, with a range of 5–100 meters depending on the environment. The weatherproof and splash-proof housing makes it ideal for both indoor and outdoor use, even in demanding conditions. Its wide operating temperature range of -20°C to +70°C ensures suitability for most environments, and the long-lasting battery lasts 12–24 months. The replaceable CR2477 battery (included in the package) makes it easy to use.

RuuviTag is designed to be compatible with multiple systems, making it a flexible and versatile solution for different uses. It easily integrates with popular platforms such as Victron Energy, Home Assistant and Homey, enabling accurate measurements combined with powerful energy usage, automation and monitoring features.

RuuviTag Pro is a rugged, IP-rated wireless sensor that measures temperature, humidity, air pressure and motion. RuuviTag Pro is based on the successful concept of RuuviTag and adds several excellent features. RuuviTag Pro is the most durable open source sensor on the market, and is perfectly suited for industrial needs as well as more demanding conditions in home use.

RuuviTag Pro is a Bluetooth sensor that measures environmental conditions and sends the information directly to your phone. With the Ruuvi Station mobile app, you can read real-time measurement data and explore history graphs. In the app, you can set alarm limits and receive a notification on your phone when conditions at the measurement site change. For example, if your freezer is defrosting, the temperature in your bedroom is too high, or the basement is too humid. There are dozens, if not hundreds, of uses for sensors.

ScrewTag Pro or ScrewTag?
RuuviTag Pro is a more durable version of RuuviTag. Both have the same operating principle and circuit board design. RuuviTag Pro has a more accurate temperature sensor, a more durable housing, improved mounting options, and a battery that allows for a wider operating temperature range. If you are not sure whether the basic RuuviTag meets your needs, especially if you plan to use the sensors in extreme conditions or industrial environments, we recommend choosing RuuviTag Pro.
