HASS gives me the next error:

2018-02-25 19:52:53 ERROR (MainThread) [homeassistant.core] Error executing service <ServiceCall cover.open_cover: entity_id=['cover.rolluik']>

Before version 0.63 i dont have any issues.

looks like it’s failing to write to the device. Maybe the device is momentarily losing connection?

I try it on a other pc and i have the same problem.
I can change the USB hub and cable but it is strange that everything works after a reboot .
But a couple of hours later i have this problem.

This a windows PC? Do you have a setting to keep the usb ports powered when entering sleep/hibernation?

5

no the first one was a odroid with ubuntu and the second one a pc with debian.
Could it be a problem with python?

Could be, but I would be suspect of hardware before software. Especially USB. USB has been a thorn in my side in the past, but I typically deal with it on windows platforms. USB has a tendency to disconnect and power off based on OS settings. When the io error occurs, can you reach it from another software package outside HA?

Hi

Same here with an odroid C2 with the HASSIO Image for Odroid C2 (with an updated HomeAssistant 115.X).
I have to restart often Home Assistant for RFXCOM to work again.

Had the same with my ubuntu 20.04 install. I disabled usb power suspend and it seems to be working fine now, had no more errors.

Hi,

Someone already tried to disabled the usb power autosuspend of the Odroid C2 with a HassIO OS ?
