Repeated 'Remote end closed connection without response' error and cannot turn switch on or off from HASS

[marthoc]

I am experiencing a problem where the following error is repeated in the HASS logs and the Decora Wifi switch cannot be controlled (i.e. flipping the toggle in HASS does nothing):

If I look back in the logs to when the switch stopped responding, this is the traceback:

My setup in my configuration.yaml is basic:

light:
  - platform: decora_wifi
    username: my_username
    password: my_password

Since that error, I cannot turn the switch on or off from HASS. However, oddly, if I slide the brightness slider in HASS up or down, the light increases and decreases in intensity. Just the toggle switch doesn't work.

Just setup a test environment and the result is the same with cli_test.py:

requests.exceptions.ConnectionError: ('Connection aborted.', RemoteDisconnected('Remote end closed connection without response',))

Let me know if I can provide any other details to debug. Thanks!

[tlyakhov]

Sorry for the late response - looks like communication with the Leviton cloud is timing out... Not sure why. Nothing obvious in the traceback. Does restarting HASS help?

[marthoc]

Hey Tim, thanks for the response. Actually this problem seems to have resolved itself - haven't seen this error in a couple of months now. Maybe Leviton's cloud has gotten more reliable? In any event, I'll close this issue now.
