To connect to a Victron Cerbo GX you will need a USB Bluetooth adapter plugged into the Cerbo.

Accurate and Durable Sensor for Versatile Conditions

RuuviTag Pro is a rugged IP certified environmental sensor for temperature, humidity and acceleration monitoring.

The Pro is based on RuuviTag’s successful concept and additionally brings several new outstanding features to the table. RuuviTag Pro is the toughest open source sensor on the market.

Waterproof Certified Temperature Sensor

RuuviTag Pro tolerates wet and rough conditions.

The IP67 certified RuuviTag Pro (3-in-1) comes with a breathable membrane that enables air humidity monitoring. It tolerates temporary wet conditions.

Note! Please keep in mind that Bluetooth signals are strongly attenuated in the water and range will be significantly reduced. Ruuvi sensors can then be used in narrow water if you want to maintain connection (for example pool or jacuzzi). If you want to measure deeper, you can attach the RuuviTag Pro to a string and take it back to the surface when you want to download the data history.

Medical Grade Temperature Accuracy

RuuviTag Pro has an extremely accurate temperature sensor on board. The sensor is designed to meet ASTM E1112 and ISO 80601 requirements for electronic patient thermometers.

Measurement resolution is  0.01 °C, while absolute accuracy is astounding at ±0.1 °C across the temperature range of –20 to +50 °C, with no calibration.

The sensor units are 100% tested on a production setup that is NIST traceable and verified with equipment that is calibrated to ISO/IEC 17025 accredited standards.

Professional Mounting

RuuviTag Pro has two strong mounting ears that allow reliable installation methods to be used. Wooden ceilings, gyproc walls, concrete foundations, you name it. Attach and measure professionally wherever you need to.

Wide Temperature Range From -40 to +85 °C

RuuviTag Pro’s casing and electronics are designed to operate without interruption in a wide range of temperatures. Maintenance is minimal because the included Ruuvi CR2477T wide temperature battery lasts up to 2 years.

Temperature, Humidity, Air Pressure and Motion Measuring Made Easy

RuuviTag is a wireless Bluetooth sensor node that measures temperature, air humidity, air pressure and movement. You can read live measurements and history data directly on your smartphone using Ruuvi’s mobile app for Android and iOS.

Use your imagination and measure almost anything at your home, at work, in your hobbies.

Wireless and battery powered temp sensors: the Ruuvi

Something quite new, and far more popular then I (Victron) anticipated to be honest: the support for the Ruuvi temperature sensors. Being powered by a small coin cell in the sensor, as well as wireless, they are super simple to install. And as such perfect to remotely keep an eye on your yacht or cabin in the winter. Or fridge or freezer temperatures, and so forth.

I have installed and am using some myself as well, and they are great. Less stress about pipes freezing up, as well as mould growing: it also reports relative humidity.

Here is a picture showing the sensor, and the reported data:

Here is how the data looks on the VRM Portal:

A few notes:

  • To read data from the Ruuvi sensor, a Bluetooth USB adapter is required. For CCGX, Venus GX, and also for the Cerbo GX. A list of suitable and tested Bluetooth USB adapters is available in the Victron Venus 2.80 Blog posted on 31/01/2022.
  • Per v2.82, multiple Bluetooth USB adapters can be installed and will all be used to read data from the Ruuvis. This is nice, as it allows expanding the range by using a USB extension cable.

See the documentation for more details about this feature.

Controlling a relay on temperature

The relays on the GX device can now be controlled by temperature. For example to switch a fan, or heating pad. Here are two screenshots showing the configuration:

Display of the Cerbo GX on how to control the cerbo temperature relays using the input from the RuuviTag

In above example, the second relay will switch when the temperature in the engine bay rises above 45 degrees, starting the fan. And it will switch off once the temperature drops below 40 degrees C.

Both the first and the second relay can be configured to be controlled by temperature. And two sets of conditions can be configured, also for the same relay.
