This is neat, I would have loved to see this a few years ago when I was working on a touchpad dimmer that I used Erlang on (the hardware was originally designed to run Linux so it was easy to put Erlang on there but having a lower-cost solution by not requiring Linux would've been great).

Erlang's remote RPC, high-quality CRDT libraries, and hot-code loading made it an incredible technology for implementing IoT software product features.
