Can Configuration Files Be Recovered From The Device?
-----------------------------------------------------
If you lost your ESPHome YAML configuration files, there's no way to recover them.
The configuration is *not* stored on the device directly - only the generated firmware is on
the device itself (technically, the configuration can be reverse-engineered from that, but only
with a lot of work).
Always back up all your files!
