- Do a manual install (linux preferred) https://esphome.io/guides/installing_esphome.html and create a venv.
- create the folder "config" and copy the https://github.com/dhewg/esphome-miot/blob/main/config/zhimi.airp.mb4a.yaml in the config folder.
Also create a secrets.yaml and fill/change accordingly
esphome compile config/zhimi.airp.mb4a.yaml- after some time the compiling is complete, a firmware.factory.bin will be saved (see path in the terminal)
- copy that firmware.factory.bin somewhere safe, use https://web.esphome.io/ and select "install" (not first use).
