Convert cloud-connected air purifier into esphome device

[cinder spindle]

I'm a big fan of matter and wanted to convert my smart air-purifier into a matter device for local control but completely failed. I couldn't even commission the device and flashing some of the example projects from espressif also didn't work.

I put a ton of work into a video documenting the whole journey (4:29 min long):

I'd love to get some feedback on the video and what I might have done wrong with my matter code.
Here's the repository: https://github.com/noranraskin/matter-levoit-air-purifier

In the end I just used an existing esphome project that worked flawlessly (in about 2 minutes) 😔

i actually went on a very similar journey, but with blueair's humidifiers. i never got to the point of custom firmware, i tried to hijack the existing BLE provisioning (this is mostly not my code but i also did a lot of this on my own before discovering the existing rust repo) https://github.com/machineonamission/blueair-ble-reverse-engineering
