OTA fail

[Uakkauakkafo]

hello,
I have a fail during OTA:

Traceback (most recent call last):
  File "/usr/local/bin/esphomeyaml", line 11, in <module>
    sys.exit(main())
  File "/usr/local/lib/python2.7/dist-packages/esphomeyaml/__main__.py", line 505, in main

    file_handle = open(filename, 'rb')
IOError: [Errno 2] No such file or directory: u'config/esp32_dth11/.pioenvs/esp32_dth11/firmware.bin'

this is my file:

USB flash work, but via OTA not.

I have "esphome" and "esphomeyaml" installed on a Raspberry Pi 3B+ with Raspbian.
I Run Home Assistant on another Raspberry.

I have also another problem and I don't know if is linked:

I use "esphomeyaml" and flash via USB, all works, I'm also able to link the all in Home Assistant and use it.

If I use "esphome" I had that issue:

~ $ esphome ESP32_DTH11.yaml run
