Monitor and maintain correct temperature in a fridge
Most foods keep well when kept at recommended temperatures. However, meat and fish products stored in the fridge are much more easily spoiled than other types of food. These products should always be stored below 3 °C, which makes it important and advantageous to monitor the temperature inside your fridge.
Temperatures inside the fridge can vary considerably between different shelves and it is difficult to monitor optimal conditions using the fridge’s thermostat alone.
If the temperature inside a fridge exceeds 6 °C, the bacteria in the food will begin to grow rapidly. In addition, cold air keeps food fresh, as it slows down natural ripening in fruits and vegetables. Read more about storing temperatures from Finnish Food Authority.
Avoid putting warm food in the fridge for temperature control and energy consumption reasons. Hot food brings moisture to the fridge, which condenses and freezes in colder temperatures. Frost on the inner surfaces of the fridge disturbs the functioning of the refrigerator and increases energy costs. It’s important to note that the temperature on the door shelves is significantly warmer than the inside of the fridge, and it doesn’t go down nearly as much as it does in the back of the fridge.
You can ensure the safety of your food and minimise food waste by monitoring fridge and freezer temperatures using Ruuvi sensors. Place one sensor in the fridge door, another one in the vegetable box and the third near the back wall of the fridge. You will notice a difference in the temperature of the different locations. With Ruuvi’s mobile app, you can track temperatures easily and set alerts for when they exceed their optimal limits to help you maintain safe conditions. The notifications are also convenient if the door of the fridge or freezer has been accidentally left open or if the fridge has broken down.
Temperature in a crisper
Temperature inside the crisper doesn’t have to be as cold as in the parts you keep meat, fish and dairy products. On the other hand, the temperature shouldn’t be too cold for the vegetables to freeze. The main purpose of the crisper is to keep in humidity and thus create an optimal environment for vegetables to stay fresh for a longer time.
In some fridges, you have the option to choose either high or low humidity setting for the crisper. High humidity is best suited for vegetables, while low humidity is better for fruits. Keep in mind not to store vegetables and fruits in the same place because some fruits emit ethylene, which ripens up and spoils vegetables quickly.
Monitor the temperature and air humidity inside the crisper conveniently with Ruuvi’s sensors.

⭐⭐⭐⭐⭐ 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!
