RuuviTag Bluetooth Sensor for Temperature, Humidity, Air Pressure, and Motion. The RuuviTag is a wireless Bluetooth sensor that measures temperature, humidity, air pressure, and motion. With the mobile Ruuvi app for Android and iOS, you can read live measurements and historical data directly on your smartphone. Additionally, you can integrate the RuuviTag sensors into your system using Victron Energy GX devices such as Cerbo GX or MultiPlus GX and view the data anywhere via the VRM Monitoring Portal. A new feature is the mobile view through the VRM Widget. With the Cerbo GX, you can control relays based on temperature. However, the Bluetooth of the Cerbo GX is not reliable enough to work with the Ruuvi sensors; an additional Bluetooth adapter is necessary. Possible adapters include: Logilink BT0037, TP-Link UB400, Ewent EW1085R4, Laird BT820, and Laird BT851. Ruuvi sensors and the app are open source, allowing for limitless creativity. Let your imagination run wild and measure almost anything at home, at work, or during your hobbies.
