From the project

Satellite Hardware Project and Documentation

The Inoa Satellite is a lightweight and secure gateway for your fuse box or industrial environment.

Please see our Project Pages for details.

There is a huge amount of IoT gateways out there, but none of these fulfill completely all of our design goals:

Usage in a rough industrial environment Hardware driven security (HSM) Inexpensive hardware to be able to finance a huge fleet of devices Low energy consumption Fuse box casing (DIN rail) Small (2 FE / 36 mm) to allow mounting in existing fuse boxes Extendable design to be future proof Modular design to adapt hardware to use cases and keep…
