Solarmi RuuviTag sensor (4in1)

Wireless Bluetooth sensor that monitors temperature, humidity, air pressure, and movement. Current data and their history can be viewed directly on your smartphone display using the Ruuvi mobile app, available for Android and iOS. With an IP67 rating, it is suitable for both outdoor and indoor environments. Powered by a 1000mAh CR2477 (Li-MnO2) battery, it lasts 2 to 3 years.

RuuviTag Integration with Victron Energy Systems
RuuviTag can be easily integrated into Victron Energy systems and use the data provided by the sensors for monitoring or setting automatic actions. The sensor communicates via Bluetooth with the Cerbo GX unit.
RuuviTag is ideal for monitoring the outdoor and indoor environment of motorhomes, caravans, vans, and boats, as well as for monitoring environmental data for Victron Energy off-grid and ESS systems.

Easy to Use
You can start using RuuviTag within 1 minute; all you need is a smartphone and the free mobile app. There are no ongoing monthly costs when using the app.
