What is the RuuviTag Pro 3-in-1?
The RuuviTag Pro 3-in-1 is a professional-grade Bluetooth Low Energy sensor designed to continuously monitor temperature, humidity, and air pressure. Sensor data is broadcast wirelessly and can be read by smartphones, tablets, Victron GX devices, Cerbo GX units, and compatible monitoring platforms.
The Pro 3-in-1 model features a fully sealed IP67-rated stainless steel enclosure, making it suitable for fridges, freezers, battery compartments, engine bays, caravans, canopies, and outdoor installations where standard consumer sensors are not reliable.
RuuviTag fridge temperature monitoring in Australia
Portable fridges and freezers are critical in Australian touring, camping, and work vehicle setups. A power interruption, loose plug, or flat battery can quickly result in spoiled food or unsafe storage temperatures.
By placing a RuuviTag Pro 3-in-1 inside your fridge or freezer, you can monitor real-time temperature wirelessly and review historical temperature data directly from your phone. Because the sensor is completely wireless, there are no cables, probes, or modifications required. Nothing passes through fridge seals and there is no additional power draw from your 12V or 24V system.
This makes the RuuviTag an ideal fridge temperature sensor for touring vehicles, caravans, camper trailers, and canopy setups used across Australia.
Phone notifications for high and low temperature alerts
One of the most valuable features of the RuuviTag Pro 3-in-1 is the ability to configure temperature alerts on your phone. You can set custom high and low thresholds so you are notified immediately if something goes wrong.
Alerts can warn you of:
- Fridge power loss
- Loose 12V plugs or connectors
- Battery voltage drops causing fridge shutdown
- Freezers beginning to thaw
- Unexpected temperature drops or spikes
This is particularly useful overnight, while towing, or when your vehicle is parked away from view. Instead of discovering a problem hours later, you know about it as soon as it happens.
Seamless integration with Victron GX and Cerbo GX systems
The RuuviTag Pro 3-in-1 integrates natively with Victron GX and Cerbo GX systems using Bluetooth. No additional gateways or hardware are required.
Once paired, temperature data appears alongside your batteries, solar input, chargers, and loads within the Victron environment. Readings can be viewed locally on a GX Touch display or accessed remotely through Victron Remote Management.
This makes RuuviTags ideal for Australian touring rigs, off-grid caravans, emergency response vehicles, mobile workshops, and remote power systems where centralised monitoring is essential.
When combined with Victron alarms and monitoring logic, RuuviTags add an extra layer of protection for fridges, lithium batteries, and temperature-sensitive equipment.
Designed for harsh Australian conditions
The RuuviTag Pro 3-in-1 is not a cheap consumer thermometer. It is built for long-term deployment in demanding environments.
Key characteristics include:
- High-accuracy temperature sensing
- Stable Bluetooth Low Energy broadcasting
- IP67 dust and water protection
- Rugged stainless steel enclosure
- Excellent resistance to heat, vibration, and moisture
Whether installed inside a fridge, mounted in a canopy, or monitoring a battery compartment, the sensor delivers consistent and reliable data in Australian heat and touring conditions.
Battery life and replacement
The RuuviTag Pro 3-in-1 runs on a CR2477 lithium coin cell selected for its capacity, stability, and temperature tolerance. Typical battery life is measured in years rather than months, even in fridge and freezer environments.
Battery replacement takes only seconds and does not affect stored data or sensor pairing.
We stock the correct replacement battery to ensure ongoing reliability and performance.

Why RuuviTag is superior to cheap fridge thermometers
Many low-cost Bluetooth thermometers are designed for indoor or short-term use. They often suffer from poor range, inaccurate readings, short battery life, and unreliable alerts.
The RuuviTag Pro 3-in-1 is designed for continuous monitoring, long-term logging, and integration with professional power systems. It delivers reliable alerts, accurate data, and system-level visibility rather than just a single temperature reading.

Frequently asked questions
Does RuuviTag work inside metal fridges?
Yes. Bluetooth signal strength is reduced slightly by metal walls, but in real-world fridge and freezer use the RuuviTag Pro 3-in-1 performs reliably in touring and caravan installations.
How many RuuviTags can I use at once?
Multiple RuuviTags can be monitored simultaneously from a single phone or Victron GX system, making it easy to track several fridges, battery compartments, or zones.
Does RuuviTag require Wi-Fi or internet?
No. RuuviTags communicate via Bluetooth. Internet access is only required if you want remote monitoring through systems such as Victron Remote Management.
How long does the battery last in a fridge?
Battery life is typically several years, even in fridge and freezer environments, depending on temperature and broadcast settings.
Is RuuviTag suitable for Australian touring?
Yes. The IP67-rated enclosure and stainless steel construction make it well suited to heat, dust, vibration, and moisture commonly encountered in Australian touring and off-grid setups.
