Choose the best option for your needs:

Easy Start With One Sensor

Easy to Use Environmental Monitoring System

For an easy to use measuring solution you will need only one or a few Ruuvi sensors and the Ruuvi mobile app. Ruuvi sensors send measurement data, which can be read with a smartphone, via Bluetooth. In the app, you may set alerts and customise the sensors to your liking.

This setup is up and running within a few minutes. No pairing is needed.

More Features With the Cloud

Complete Solution
for All Monitoring

You will get all the best features with Ruuvi sensors and Ruuvi Gateway. The Gateway routes the sensors’ data to Ruuvi Cloud.

The Cloud enables remote monitoring via the Internet with trusted email alerts and longer history. With Ruuvi Gateway you will also get a longer Bluetooth range for your sensors.

The Gateway works with your own Internet connection via a Wi-Fi or an Ethernet connection.

For Advanced Users

Ruuvi products are open-source. You can configure the Gateway to send data to a third-party cloud service and integrate Ruuvi to your existing system.
