Thanks for pinging us on NervesHub. It’s technically private beta right now and we have a couple companies regularly using it in production. At the moment, our focus is on improving device authentication and first-time device registration. That has turned out to be more work than expected so we have been quieter on announcing progress. I expect that we’ll have something working fairly well by end-of-year, but with very rough docs.
If you’re building custom hardware right now and anticipate using NervesHub, I’d add an ATECC508A (~60-70 cent adder) to your board. That chip securely stores the private key used for authentication and locks down a couple other important pieces of device information in one-time-programmable memory. The chip can also be used with Amazon IoT, etc., so you’re not locked into NervesHub.
