This is interesting as an example of just how complicated and elaborate a toolchain you can use to build something dead simple.

There’s a lot that comes for free by adding all these libraries and crates and steps. But from what I can tell it comes down to:

let _ = if fan_on { fan.set_high() } else { fan.set_low() };

Okay, I read up on iroh. It has some really interesting stuff in it but I see an uncanny valley here.

It’s not simple enough to debug a connection failure easily, but it’s not magical enough to guarantee connectivity. Straight tcp with dns can be hard to debug; and no magical networking stack can really guarantee connectivity. I guess iroh’s strength is connectivity but I don’t know what happens if you can’t find a path.

The third dimension is privacy and anonymity, and I can’t tell if the story there is stronger than other p2p+relay protocols.

So it’s in the middle but at a different point in the space.

It's unclear to me why they needed to compile Rust to WebAssembly to write a website. It looks like iroh has a JavaScript API:

https://docs.iroh.computer/languages/javascript

Edit: actually, that's a Node.js-specific API. For browsers, it seems like they should have a platform-independent JavaScript/TypeScript API that includes a WebAssembly file (if needed) instead of expecting you to compile WebAssembly yourself.

iroh is very interesting and in many way it could get traction for IoT.

Now I am not sure it is feasible but it would be interesting to have it available in esphome. I feel this is really where real adoption happens.

Any plans to standardize Iroh IoT protocols, e.g. Matter over Iroh / Some other standard that would be plug-able to things like Home Assistant?

While this is neat, it strikes me as the software developer's idea of a "smart fan". The engineer in me says that an actual "smart fan" would be one whose blades are designed to produce maximum airflow with minimum noise (variable pitch? avoiding turbulence?)

Iroh is probably one of the best shots we have at making IoT finally secure with the built-in endpoint-to-endpoint encryption. The only thing that is missing is an embedded QUIC stack, the setup described in this article sees a little bit too hacky (4 MiB of PSRAM, really?).

In a heatwave, you need AC, not a fan. Moving hot air around without cooling it is pretty much useless.
