Ruictec’s TD04 brings open source software to LoRaWAN-based asset tracking, combining solar-assisted power and BLE–GNSS switching.
Ruictec has introduced the TD04 Asset Tracker, an open source, low-power tracking device designed for long-term fleet and asset monitoring across mixed indoor and outdoor environments. Developed in China, the TD04 combines LoRaWAN connectivity with Bluetooth Low Energy (BLE) and dual-band GNSS (L1 + L5), positioning it as a flexible alternative to cellular-based trackers.
At the core of the device is an adaptive positioning architecture that automatically switches between BLE-based indoor tracking and GNSS-based outdoor positioning, optimising both accuracy and power consumption. The tracker delivers approximately 1–2 metres accuracy outdoors and 2–4 metres indoors, with all location data transmitted over public or private LoRaWAN networks.
The TD04 is LoRaWAN 1.0.3-compliant, supporting both OTAA and ABP activation modes, and operates across multiple global frequency bands, including EU868, US915, IN865, AS923, and CN470. With a communication range exceeding 1.5 km in urban environments, it is suited for wide-area asset visibility.
Powering the device is a 6000 mAh rechargeable battery with support for a 1.3 W solar panel, enabling up to six months of standby time. Ultra-low sleep currents, motion-triggered wake-up, and adaptive BLE–GNSS switching further extend operational life. An IP67-rated enclosure and wide operating temperature range make the tracker suitable for harsh outdoor deployments.
From a software perspective, Ruictec adopts an open source approach, exposing the front-end visualisation via the location_web repository and the back-end logic through the edwei development library. This allows developers to customise dashboards, modify data workflows, and integrate third-party platforms without vendor lock-in. The TD04 is available on Tindie for USD 49.
