Movement

RuuviTag knows exactly when it's moved. Known when the postman opened your mailbox outside and get notified if someone visited your hotel room while you were gone.

"Avoided water damage"

I had a RuuviTag in my house's boiler room. One day I noticed suddenly increased air humidity levels and went to see what's going on. Found a leaking water pipe!

“Interesting history logs”

Every morning my dad checks temperature logs from his phone to see how the weather was at night.

“Perfect hiking buddy”

There are quite a lot of devices for safe travels in the mountains. I just came back from a hiking trip in the mountains where I used the the Ruuvi sensor for measuring temperature.

FAQ
Why would I need Ruuvi products?

The use cases for Ruuvi sensors are unlimited and the only limit is your imagination. Read more about use cases and user experiences on our blog and our forum.

The Ruuvi products are designed in Finland and produced in France with the highest quality standards to ensure the best possible products at the end!
We do not believe in bots (at least on our webpage)! We are very happy to answer any of your questions regarding a product or to support you with any issue.

Is my mobile device compatible with Ruuvi products?

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

Is RuuviTag water-resistant?

RuuviTag is IP67 certified (water-resistant, tested in 1 meter depth). If you are looking for a fully waterproof sensor, please check out RuuviTag Pro (2in1), which is IP68 or IP69K certified (waterproof, tested in 50 meters depth). See the certification of each sensor directly on the product pages.

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.

What are the operating conditions of the Ruuvi sensors?

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.

How to monitor the Ruuvi sensors remotely?

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.

Can I use the Ruuvi sensors to monitor my sauna?

Yes you can!

The sensor’s temperature increases slightly slower than the sauna’s temperature and the readings depend a lot on where it is placed inside the sauna. But that’s not a problem! Just check at the first use what is the sensor reading when the sauna is just perfect for you. Then, set the alert to this specific value to get notified when the sauna is ready and to get the perfect temperature every single time!

Please note, that if the sensor is reaching temperatures above 70°C (85°C with a custom battery) you should consider setting the sensor somewhere lower in the sauna to avoid any thermal damage.

What is the 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.

Are Ruuvi products compatible with a home assistant?

The Ruuvi products are not directly integrated into home automation systems. However, all our products are open-source and can be integrated to any home automation system, requiring some further development. Discussions and tutorials about the topic are available on our forum.

How fast is the shipping?

We work with the best courier partners and do our best to proceed to the shipment within 24 hours from the order! All the products are sent from our warehouse in Finland and delivery time depends obviously on your location. We will provide you with a tracking number automatically to your email so that you can follow where your Ruuvi package is going.

Can I see the data history of my Ruuvi sensors?

Yes you can!

Up to 10 days with the Ruuvi sensors alone

The Ruuvi sensors have built-in storage enabling them to store 10 days of measurement data. You can import the data to the Ruuvi Station mobile app at any point by pressing “sync” button in the app. This means that even when leaving from the Bluetooth range, you will be able to see a detailed 10 days history when coming back and synchronizing.

Up to 2 years with the Ruuvi Gateway and our cloud service

If this 10 days of data is too short, or that you want to be able to monitor your sensors remotely, you should consider the Ruuvi Gateway. It enables you to analyze up to 2 years of data history on the convenient and intuitive desktop version of Ruuvi Station. Also, no need to synchronize, the Ruuvi Gateway is continuously sharing data to the cloud and it is retrievable from anywhere around the world as long as you have an internet connection.
