Ich habe seit 2023 schon 3 Sensoren im Wohnmobil verbaut (2 ProSensoren in der schwarzen Hülle für Kühlschrank und im Gefrierfach). Ohne Probleme kann ich so auch mal gegensteuern, wenn die Temperatur „ausreißt“). Die entsprechenden Temperaturgrenzen können auf der App eingestellt werden und ich erhalte eine Warnung ⚠️. Hat mir schon mal mein Gefrorenes gerettet.
Jetzt im Winter hatte ich die Kühlschrank Sensoren für Bad und Garage genutzt. Namen in der App geändert.
Nun habe ich mir noch zwei Sensoren für das WoMo bestellt. Einfach super empfehlenswert 👍
Anzumerken ist, dass die kälteresistenten Batterien nicht per Post nach Deutschen verschickt werden. Komisch, da die Sensoren mit Batterie verschickt werden. Die normalen (im Handel erhältlichen) funktionieren bei aber bei minus 25 Grad 🤗

Immediate connectivity via Bluetooth and able to see how my palms are doing in their heated winter polycarbonate boxes temperature.
Love the RuuviTag sensors!!!
After integrating four RuuviTags into my Victron Cerbo GX / VRM system in our Rapido motorhome, I can honestly say they have transformed the way I monitor the vehicle.
The setup now provides live temperature, humidity and pressure monitoring directly inside the VRM portal, allowing me to monitor critical areas including:
Battery Box
Orion DC-DC Charger Compartment
Engel Fridge
Main Rapido Fridge Area
What impressed me most was how seamlessly the RuuviTags integrated with the Cerbo GX via Bluetooth. Once connected, the data appears natively inside VRM and can be used for real alarms and automation.
I have now configured:
High temperature alarms
Low temperature alarms
VRM email notifications
Relay-triggered audible siren alarms
The system is now capable of warning me immediately if:
the lithium battery compartment gets dangerously cold
the battery box overheats
the Orion compartment becomes too hot
ventilation or airflow problems occur
The accuracy and stability of the readings have been excellent. The tags update reliably and provide a very clear picture of what is happening inside the motorhome.
One of the major advantages is that the system no longer relies on older digital-input alarm methods or complex workarounds. The RuuviTag + Cerbo GX combination feels like a modern, professional-grade monitoring solution.
The compact size, long battery life and wireless operation make installation extremely easy. No extra wiring was required for the sensors themselves.
For anyone building a Victron-based off-grid system, especially in a motorhome, caravan, marine or lithium battery installation, I would highly recommend RuuviTags.
They add a level of visibility and protection that is difficult to achieve any other way at this price point.

Easy Start With Sensors
Monitor Your Restaurant With Bluetooth Sensors
If you’d like, you can start with just one or two sensors. All you need is a smartphone and our free mobile app to go with the sensors. There are no ongoing monthly costs using the app.
In this scenario, you can get started within minutes. You’ll receive real-time readings from sensors within Bluetooth range on your phone, complete with helpful historical graphs and alerts.
In case your phone occasionally goes out of range, you can still access a full history of the sensor’s data for the previous 10 days within the app. Moreover, if needed, you can export measurement results as a CSV file directly from the app.
The RuuviTag has a user-replaceable battery that lasts up to two years. The device requires very little maintenance.
