Basements are usually on the ground level, or below it. As a result, there are multiple ways water can get into space. With relative air humidity monitoring, you can’t ensure the moisture levels of the structures, but you can receive a good indication of possible problems arising in the basement. If you take care of your basement’s environmental conditions before more serious problems occur, you could save a fortune.
Basement renovations should almost always be left at the hands of professionals. A wrongfully executed renovation can actually increase the problems you were trying to fix. There are multiple ways of trying to decrease the humidity in a basement. These include: heating the basement, improving drainage, changing the materials inside the basement, and building a bottom well.
With Ruuvi’s sensors, you can conveniently check the relative and absolute humidity levels in the basement. Air humidity in the basement fluctuates with outside air humidity. Hence, during summer heat, the relative humidity in a basement can reach levels between 80% and 90%. If these levels of humidity are constant in the basement, problems may arise in the long run.
Ruuvi’s sensors measure air humidity and temperature. Install the sensor on a counter in the basement, or alternatively, attach it to a wall. This is the best way to measure air humidity in the basement. Ruuvi’s sensors send measurement data directly to your phone via Bluetooth. In the Ruuvi application, you can examine long-term graphs and therefore be aware of the differences in air humidity overtime. In addition, you can create alerts to alert you when your pre-set threshold is exceeded.
Measure your basement’s conditions and you will receive valuable insights regarding what is going on in your basement!

⭐⭐⭐⭐⭐ Excellent sensors for RV monitoring and Victron VRM integration
I am extremely satisfied with my Ruuvi sensors.
I use several of them in different locations inside my motorhome: in the refrigerator, battery compartment, living area, kitchen area and other positions. Installation was very simple and the sensors have been working flawlessly from day one.
What impressed me most is the excellent integration with the Victron ecosystem. Through Victron VRM I can monitor all sensor data remotely 24/7, which is incredibly useful when living and travelling off-grid.
The accuracy is outstanding. The pressure readings of different sensors are almost identical, showing only minimal differences, which gives me great confidence in the quality of the measurements. Temperature and humidity readings have also proven to be very reliable.
I have even used the sensors to evaluate the performance of a portable compressor cooler. Thanks to the precise temperature logging, I was able to see that the cooler dropped from 20°C to 0°C in about 30 minutes and reached -20°C in less than an hour. Without Ruuvi sensors, such testing would have been much more difficult.
Battery life has been excellent, setup is easy, and the overall user experience is outstanding.
For anyone using Victron equipment, RVs, boats, off-grid systems, refrigerators, freezers or environmental monitoring, I can highly recommend Ruuvi sensors.
Hard to say anything bad. It does exactly what it promises.
Excellent!
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.
Works well and bluetooth connection works from quite far away even with a few walls in between.
perfect to log my boat conditions when i’m away, and check pressure variations in real time when i sail
Excellent, now you need to produce a wireless sensor integrated with victron to measure water tank quantity.
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 🤗
