ESP (ESP32/ESP8266, Board/Sonoff): not related

Affected component: upgrade

Description of problem: I tried to upgrade from esphomeyaml 1.10.1 to the newest esphome version. After installing the newest esphone version, nearly all commands (compile, run, logs..) don't work anymore and triggering the exceptions above.

Problem-relevant YAML-configuration entries:

Additional information and things you've tried:

I tried to reinstall the old esphomeyaml, but still doesn't work.

Nevermind, I found the solution.

I had to rename the root keys in my existing node configurations from esphomeyaml to esphome.

Maybe it would be a good idea to show an upgrade message, if the old key is found? Leaving this issue open - if you don't like this idea, just close it.

Thanks for your great work!
