Never wonder "Is my vehicle safe?" again.
The ThermoBuddyTracker (TBT) is an intelligent IoT tracking device designed specifically for vehicles in storage — boats over winter, classic cars in garages, and motorhomes between adventures. Get real-time location, temperature alerts, battery voltage monitoring, and motion detection delivered straight to your phone.
Precision GNSS location with geofencing alerts if your vehicle moves unexpectedly.
Get alerts when storage conditions risk damage — frost, heat, or condensation.
Monitor your vehicle's battery health and receive low-voltage warnings.
Long-range LoRa for remote storage or 4G for instant cloud alerts — your choice.
