Recently, we’ve been working with IOTA’s team by adding their MAM (Masked Authentication Messaging) support to RuuviTag.
This made RuuviTag the first IOTA compatible low-power sensor device available.
To showcase the new feature and to allow developers to use RuuviTags in their IOTA/Ethereum projects as soon as possible, we headed to Frankfurt where a 5-day blockchain/tangle hacking event took place.
The sold out event was organised by Frankfurt Business School Blockchain Center and had a several fascinating speakers.
The week was really productive and inspiring in many ways:
Dozens of talented developers built their real-world IoT business [proof of] business concepts on top of IOTA/Ethereum using Raspberry Pi / HiKey hardware platforms and RuuviTag sensors.
Find #iothackffm on Twitter and on LinkedIn.
After brainstorming on the first day, teams decided what to build and if they would like to use RuuviTags in their projects.
The teams created in total 15 (!) awesome projects and presented those at the closing event on Friday.
This is one of the projects:
BountyBoard is a skateboard that has a RuuviTag on bottom to measure acceleration and orientation of the board. Team behind this concept project is Martin Maurer, Philipp Sandner, Daniel Grassinger and Otso Jousimaa.

RuuviTag is a Bluetooth sensor that monitors environmental conditions and sends the data directly to your mobile device. The Ruuvi Station mobile app allows you to view real-time accurate measurements and historical graphs. The app also provides customisable alerts to notify you of critical conditions, such as a melting freezer, excessively high bedroom temperatures that could disrupt sleep, or elevated humidity levels in your basement.
Onboard Sensors (4-in-1)
Temperature: °C, °F, K; typical accuracy ±0,2 °C @ 5-60 °C (±0.36 °F @ 41-140 °F).
Air humidity: RH-%, g/m3, dew point; typical accuracy ±3 RH-% @ 20…80 %. Range: 0-95 %.
Air pressure: Pa, hPa, mmHg, inHg; typical accuracy ±1 hPa. Range: 500-1155 hPa.
Motion: Movement counter. Counter is incremented when acceleration exceeds the threshold on any axis.
Operational Conditions
Operating temperature (with stock battery): -20 °C to +70 °C (-4 °F to 158 °F).
Absolute maximum operating temperature: -40 °C to +85 °C (-40 °F to +185 °F).
Housing: IP67, splash-proof, non-condensing location.
Battery: User-replaceable CR2477 (included). Supports extended operating temperature range battery CR2477T.
Battery lifespan: Estimated 12 to 24 months.
Certifications: CE, FCC, ISED, TELEC, IFETEL, NOM, RTCA DO-160 category H, RoHS, IC, HVIN, IMDA, OFCA, ICASA, POTRAZ.
Bluetooth range: 5-20 meters (indoor), 20-100 meters (outdoor). The sensitivity of the receiving mobile device’s antenna, obstacles and wall materials affect the range. For increased range, use the Ruuvi Gateway router as a receiver.
App Features
Free and easy: User-friendly free app, signing in is optional.
Platforms: Android and iOS.
Alerts: Configurable Bluetooth push alerts with customisable messages.

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