Tying it all together
summary
NervesHub is a production Elixir app that delivers over‑the‑air firmware to six‑figure fleets, using mutual TLS for device auth, an Erlang SSL engine hook to reject TLS before costly handshakes, and per‑device Phoenix channels for firmware, console and extension traffic. It runs real‑time UIs via LiveView, background jobs with Oban, and shifts time‑series and logs toward ClickHouse; it generates firmware deltas to save megabytes per device and uses a single orchestrator singleton to coordinate deployments reliably.
