Mould in the camper van
There are several things to consider when heating up the interior of the camper van; energy consumption and the living conditions for your family, as well as optimal conditions for the van itself. Heating consumes a lot of electricity, but it can also prevent excessive accumulation of moisture indoors and inside the structures of the van. Cracks in structures, a leakage, poor ventilation or cold air can cause moisture to build up inside the van. High humidity can lead to issues with mould. Staying in a mouldy van can cause allergic reactions with symptoms such as nasal discharge, eye itching and fatigue. If the caravan is not ventilated properly, mouldy air remains inside and the amount of allergens increases.
Battery maintenance
Batteries of a camper van must be stored in suitable conditions for proper functioning. For example, a lithium battery should not be charged if the temperature is below 0 °C. When travelling in colder climates, special attention should be paid to the ambient temperature of the batteries to keep them working for a long time. Batteries may also be removable, allowing them to be stored in more favourable conditions than the van itself.
Fridge and freezer
Batteries may also be removable, allowing them to be stored in more favourable conditions than the van itself. If the sun shines directly on the side of the van with a fridge, the fridge will consume significantly more energy than if it was standing on the shadowy side. In the worst case, the fridge will warm up too much, which will cause the food to spoil. Set an alert from the Ruuvi mobile app to receive a notification if the temperature is above 6 °C. The temperature of a freezer should be kept at around -18 °C.
Storing of a camper van
It is necessary to monitor the storing environment of the camper van especially during the winter to prevent relative humidity from rising too much. Sealed tarp or a thick layer of snow is not a good cover since they make it impossible for moisture to evaporate and thus may cause issues with excessive humidity levels. Even when stored indoors, the humidity of a van can get too high without proper ventilation or moisture absorbers. There is not a specific maximum percentage of relative humidity, but the most important thing is to ensure ventilation and prevent moisture build-up.
We recommend monitoring the conditions of the storage of your camper van with Ruuvi measuring devices. This way your van will not be damaged by environmental conditions because of lack of awareness of what the conditions actually are. If you want to monitor these conditions remotely, we recommend purchasing a Ruuvi Gateway router. The Ruuvi Gateway transmits the measurements from RuuviTags over the Internet to the Cloud, allowing you to track measurement results even outside the Bluetooth range. Set alarms in the Ruuvi app and get notifications if you need to change anything in the storage area.

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.
perfect to log my boat conditions when i’m away, and check pressure variations in real time when i sail
