Needed software:
- HFS HTTP fileserver (for serving firmware file) - https://www.rejetto.com/hfs/?f=dl
  - Not all HTTP servers will work, it has to support streaming, I think
- Postman (for instructing device to download file from URL) - https://www.postman.com/downloads/

- OTA protocol documentation: https://github.com/itead/Sonoff_Devices_DIY_Tools/blob/master/SONOFF%20DIY%20MODE%20Protocol%20Doc%20v2.0%20Doc.pdf

Steps:
- Prepare your firmware you want to flash (for example from ESPHome)
