Title says it all really. :> The entire protocol is documented within the code because that seemed like the most logical place, especially inside the union EuromProtocol. Do note though that I only have access to the Polar 16CH model, there's also a 12CH variant but that doesn't support heating. I don't know if that unit uses the same protocol or not (or even how units from completely different product lines work). I did have a very old unit that finally died and it just used NEC, in any case.

I'm already using this remote in "production", so all features should be working as expected.

Builds are failing because a deprecated github actions/cache@v2 module is used 🤔 should probably be fixed in a separate PR (and maybe by one of the regular maintainers?)
