Five-star support, from planning to after-sales
A rotating five-star selection from around 150 Google reviews for Solar 4 RVs equipment, advice and ongoing support.
Absolutely stellar service from Cameron at Solar 4 RVs. Initially had him quote up a solar system for my campervan back in June 2024 and then when I was ready to purchase in November 2024 he was able to give me the best prices for every product and so I went ahead with the order.
Also gave me some tips to commission the system once I installed the products. Stoked on the Victron gear. Thanks guys!
Purchased a 12v/15a battery charger in 2023. Had issues with it today (2025). Called their info number and explained. Instantly agreed to accept it as a warranty issue and dispatched a replacement without any problems. Extremely quick service and item dispatched express courier that same day. Outstanding customer service. Thank you.
Purchased a literal boat load of electronics from them for our vessel. It all works great and they did an amazing job setting up the panel. We have had the gear a few years now and still reach out when we need help. Great customer service!

Precision Ruuvi Wireless Sensors for Off-Grid Monitoring
Maintaining optimal conditions inside your caravan, RV, marine vessel, or 4WD canopy is essential for comfort and equipment longevity. Our range of Ruuvi wireless sensors provides highly accurate, real-time data for your mobile living spaces. Whether you need to monitor the temperature of your travel fridge, track humidity in a marine cabin, or detect motion in an off-grid tiny home, these robust devices deliver dependable performance.
Built for demanding environments, the RuuviTag Pro series features highly durable enclosures that withstand extreme conditions. These Bluetooth-enabled sensors integrate seamlessly with off-grid monitoring systems, allowing you to track environmental changes directly from your smartphone or an advanced central display.
Practical Applications for Mobile and Off-Grid Living
From commercial transport trucks to weekend camper trailers, knowing your exact environmental conditions prevents spoilage, condensation, and equipment failure. Key applications include:
- Fridge and Freezer Tracking: Ensure your food and beverages stay safe by placing a Ruuvi tag inside your cooling compartments.
- Cabin and Canopy Humidity: Monitor moisture levels in your boat or 4WD to prevent mould and condensation build-up.
- Equipment Protection: Track the temperature near sensitive electronics or inside battery compartments to prevent overheating.
- Motion and Movement: Receive alerts if a storage hatch or door is opened unexpectedly while parked.
Seamless Connectivity and Long Range
The core of the system relies on powerful Bluetooth broadcasting, providing excellent range even through insulated caravan walls or marine bulkheads. For users who require remote access away from their vehicle, adding a Ruuvi Gateway Router allows the sensors to push data directly to the cloud. This means you can check your canopy temperature or boat humidity from anywhere with an active internet connection.
As an Australian family business with a decade of experience, we pride ourselves on delivering high quality products backed by comprehensive before and after support. We ensure fast dispatch so you can upgrade your environmental tracking without delay.
How to Choose the Right Ruuvi Sensor
Selecting the ideal device depends on exactly what you need to measure and the environment where it will be placed. Compare your requirements against the specific capabilities of each model:
- RuuviTag Pro Sensor (4-in-1): The ultimate all-rounder. It measures temperature, humidity, air pressure, and motion. Best for comprehensive cabin climate control and predicting weather changes based on barometric pressure.
- RuuviTag Pro Sensor (3-in-1): Measures temperature, humidity, and motion. Ideal for monitoring fridges, freezers, and living areas where air pressure tracking is not required.
- RuuviTag Pro Sensor (2-in-1): A rugged industrial model focusing purely on temperature and motion. Perfect for engine bays, external battery boxes, and harsh commercial environments where extreme durability is the priority.
- Ruuvi Gateway Router: Choose this if you need to monitor your sensors remotely via Wi-Fi or Ethernet. It collects Bluetooth data from your tags and uploads it to the cloud for real-time access from anywhere.
If you are still deciding between models, our detailed Ruuvi Sensor Comparison Guide breaks down the specifications further. You can also integrate these devices into dedicated temperature monitors to build a complete smart ecosystem for your rig.
