Firmware will not compile any longer - dmaker.fan.p33

I haven't been able to upgrade my Mi Smart Fan 2 for the last few weeks. Any thoughts?

Already fixed, see #90 and #91. Your local esphome installation just has the old version cached

[scrampker]

Awesome, I usually see these sorts of issues get corrected after a few weeks, but this one dragged on. I'll see if I can refresh my cache. Thanks!

I've tried uninstalling my ESPHome add-on, and digging through folders looking for cache.. but then I also found that the cache refreshes after a default 24 hours. It's been 2 weeks, so not sure what's up. I did a bunch of searching but I see no good advice to clear out all the code/cache. Any ideas?

I'm using the official version from the add-on store in HASS. I feel like I'm missing something obvious here. Found a few threads that implied there's not really a cache I can delete, and re-installing the add-on should have pulled the latest official release. Is this just a delay on the hassio/esphome side of things and there's nothing really to do except wait for the code to propagate? or are others already working just fine with the normal install?

[dhewg]

No idea about the addon, but is your local config actually pointing to this git repo? Compare the files in the config/ folder committed here with yours

Derp, I was still using cristianchelu's fork from a fix he did a while back. I hadn't touched it since. All good now.
