Works with

WiCAN PROHome AssistantWireGuard

ESPNetLink gives a WiCAN PRO its own mobile data link and position fix. It plugs into the USB host port, connects over LTE Cat-M1 or NB-IoT, and opens a WireGuard tunnel so Home Assistant can reach the car wherever it is parked. The GNSS receiver and the onboard IMU add live tracking and wake-on-motion.

It also works on its own as a small LTE gateway for low-data-rate sensors. Configuration happens in a lightweight web interface or over the command line, and the firmware is developed in the open on GitHub.
