IoT Green Energy

Hand-built firmware images do not scale: every device variant multiplies build effort and risk, and insecure update paths are a liability for a growing IoT fleet.

We deployed an automated build system based on Yocto for IoT devices (Raspberry Pi 4, CompuLab imx8plus), tightly integrated with AWS Greengrass and managing over-the-air updates with Mender.

Reliable, uploadable image creation with hardware security via fTPM 2.0 and hardened update flows — reducing risk across large-scale IoT deployments.
