Fertilise your plants, water them regularly, and ensure proper conditions in the greenhouse with the help of Ruuvi sensors. With these tips, you will have a rich harvest. Optimising greenhouse conditions is one of the most important things you can do to increase the harvest from your plants. When you closely monitor the temperature in your greenhouse, you can already start growing crops in the early spring and collect your harvests well into the autumn.
During springtime, sprouted tomato seedlings can be transferred to the greenhouse when the temperature does not fall below 15 °C during the night. Cucumbers can be transferred to the greenhouse when the temperature remains constantly above 18 °C.
The temperature in a greenhouse should be lower during the night and higher in the daytime. Take note that the temperature should not rise above 26 °C. Temperature monitoring is also important during the winter if you have moved your plants to your greenhouse to overwinter.
Monitoring relative humidity also plays a crucial role in growing plants. Air that is too humid can expose plants to various diseases and cause them to rot. On the other hand, air that is too dry will cause the plants to dry up and the photosynthesis will not be efficient. It is important to ventilate the greenhouse frequently.
You can monitor the humidity and temperature in the greenhouse using Ruuvi sensors. The greatest benefit comes from customisable notifications. Receive an alert about undesired conditions based on minimum and maximum readings you want, depending on the season and the growing phase.
Greenhouses are often built in an east-west direction. There are guidelines as to which plants should be placed on the sunny side and which should be on the shadowy side. Since the environment may vary greatly in different parts of the greenhouse, it may be a good idea to place at least two sensors at the opposite ends.
Ruuvi sensors send temperature and humidity measurement data to your mobile device where you can view real time data and history graphs. In addition, you can set custom notifications and personalised alert messages.

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.
