RuuviTag is a Bluetooth sensor that monitors environmental conditions and sends the data directly to your mobile device. The Ruuvi Station mobile app allows you to view real-time accurate measurements and historical graphs. The app also provides customisable alerts to notify you of critical conditions, such as a melting freezer, excessively high bedroom temperatures that could disrupt sleep, or elevated humidity levels in your basement.

Most Common Questions
Under what type of weather conditions can the RuuviTag function?

Temperature

Electronics of the Ruuvi sensors can support temperatures between -40°C (-40°F) and +85°C (+185°F). However, the market standard CR2477 batteries’ operation range is usually between -20°C (-4°F)  and +70°C (+158°F). Do not exceed these temperatures without shopping our custom made wide-range battery, which is designed to operate with the same limits as the electronics of the sensors.

Dust & Water

All the sensors are resistant to dust and moisture. Some of the sensors are IP67 certified (water-resistant) and some are IP68 or IP69K certified (waterproof). See the specific certifications for each sensor on the product page. Please keep in mind that water lowers drastically the range of the sensors.

What is the Bluetooth range?

Using only Ruuvi sensors

The sensors send data packages via Bluetooth to your mobile device. Thanks to optimized sensor antenna design, in perfect conditions without any obstacle, the Bluetooth range is up to 200 meters, which is way more than that regular Bluetooth speaker.

Please keep in mind that any obstacle, especially metal enclosures, concrete walls, or proximity of water will lower the range.

Using Ruuvi sensors + Ruuvi Gateway

The sensors send the same data packages as above with the same emission power. However, the reception antenna is way better on the Ruuvi Gateway than on a regular mobile device. The highest range ever recorded, in optimal conditions, between the Gateway and the sensors is a vertiginous 2000 meters!

The Ruuvi Gateway shares then data to the cloud service and the sensor readings are then retrievable from anywhere in the world as long as you have an internet connection.

Can I monitor from anywhere?

The Ruuvi sensors can be monitored with just a mobile device and the Ruuvi Station app within the Bluetooth range. If you want to monitor conditions from further, you’ll need our Ruuvi Gateway product.

The Gateway is connected to the internet and listens to sensors with a higher sensitivity than a regular mobile device. The test results talk by themselves: up to 2000 meters between the Gateway and the sensors, compared to 200 meters between a mobile device and the sensors (test realized in optimal conditions without any obstacle).

Then, the Gateway shares the data to our cloud service. The sensor measurements are then retrievable, either from the mobile app or our web interface from anywhere in the world as long as you have an internet connection.

Do I need to charge my Ruuvi sensors?

No, the power of the Ruuvi sensors is supplied by CR2477 coin batteries, included in the box. One battery lasts usually between 2 to 3 years in continuous use. The battery is easily replaceable by the user making our products very sustainable and lowering their maintenance costs to a few euros every two years.

Will RuuviTag work with my phone?

The Ruuvi Station app can be downloaded both from the Play Store (Android) and the App Store (iOS). It is also available for tablets.

"Easy remote monitoring"

I use the RuuviTag to monitor the conditions of our cottage when we're not there. It's the most convenient way I've found to monitor safe temperature and humidity

John, 62
“Abnormal tempereture detected”

I received an alarm from Ruuvi Station on my phone saying "temperature too low". A window was broken during winter, and were able to fix it before any major damage.

Steven, 33
“Really useful accessories”

I like to use the RuuviTag holder, it is 100% impossible for my pets to have access to the sensor or to inadvertently eat it.
