Mqtt is the easiest imo, with the right messages sent from the sensor, HA will discover it automatically. That’s also what other add-ons like zigbee2mqtt do actually.

I have an idea for a talk for the next Goatmire conference… Something about robotics with nerves, droids, and a forgotten Jedi order… That’s how I got the idea of renaming my bot ex2d2 😅

But to simply connect a nerves based sensor to HA, there are several options
- push sensor data to mqtt, it means using the mosquito broker on the HA box
- expose a REST api on the sensor as there is a REST sensor in HA
- mimic the esphome protocol, I don’t know how hard it would be to do in elixir

So fast you can barely see it…

With a small screen, we could also provide a lib that gives the robot a face like fluxgarage: github.com/FluxGarage/R...

A small robotics kit running nerves would be really cool. I already have had some success controlling a differential robot with nerves circuits in livebook. Connected to the robot running nerves through wifi and played with it wirelessly in livebook. I called it Exbot but Ex2d2 would be cool too 😉

HA runs in docker containers, and HAOS is buildroot based. So in theory, nerves could be replacing HAOS. But not sure yet if I see the point. However, with my nerves port on an old Nexus 7, I want to run a small flutter app running chromium connected to my HA box so I can have a wall dashboard.

My cover is blown…
