Core: Homekit_controller: Update for cover.garage_door fails: TypeError: can't concat bool to bytearray

[rudgr]

Home Assistant release with the issue:
0.8.3

Last working Home Assistant release (if known):
unknown

Operating environment (Hass.io/Docker/Windows/etc.):
Hass.io/Raspberry Pi 3 Model B

Component/platform:
https://www.home-assistant.io/components/homekit_controller/

Description of problem:

Every now and then errors, like the one reported below, keep appearing in home-assistant log. Sometimes my homekit enabled garage door keeps functioning, sometimes it looks like the home-assistant UI Cover state gets out of sync with the actual state of the garage door (and therefore open/close commands don't work anymore). Usually, restart of home-assistant "fixes" the errors from log, but after some time they start appearing again.

Problem-relevant configuration.yaml entries and (fill out even if it seems unimportant):

# Discover some devices automatically
discovery:
  enable:
    - homekit

Traceback (if applicable):

Seeing the same behavior with motorized blinds, so this isn't specific to garage doors. My HomeKit device is a VELUX Active Gateway (model KIX 300).

Hi Guys

The good news is this is a dupe of #20760, and that error should hopefully not occur in the just released 0.87 tag.

Possible bad news - if you upgrade and still have issues theres a good chance its #20800 and the fix for that is waiting to be reviewed + merged.

If you have any other homekit_controller problems and i'm not tagged in the GH issue already, feel free to @ me.

[rudgr]

great, will give it a try, tx!

[rudgr]

updated to home assistant 0.87.0, error seems gone (for the moment at least), but now my Cover UI element displays a warning/error:

entity not available cover.garage_door

[Jc2k]

Any exceptions in your logs? There is a known regression that should be fixed in 0.87.1 that is probably what this is but if you post the exception I can check.

Is there some way to contact you directly? I’d like to capture some logs to help add more realistic tests for this component and don’t want to litter github.

tx for the reply @Jc2k

[Jc2k]

Argh no anything but that...

HASS.io uses a version of OpenSSL that is too old and busted for the version of homekit that has the fixes in, and we are stuck until the HASS.io team switch from Alpine 3.8 to 3.9.

(I’m just a user, but have raised a HASS.io ticket and asked on discord. It will happen but not clear when yet. But this has bitten a bunch of users so I’m going to see if I can come up with a workaround in the mean time).

[rudgr]

haha, ok, tx for raising the ticket!

[rudgr]

FYI: updating to home assistant 0.87.1 did indeed not fix this issue.

https://github.com/home-assistant/hassio/issues/903 is the hass.io issue you are referring to?

[Jc2k]

Indeed it is

[Jc2k]

@rudgr I just saw a PR land in hass.io that might be related. Hopefully nearly there with this issue!

[Jc2k]

The UnsupportedAlgorithm exception should be gone for HASS.io users now 0.88.0 is out - AIUI HASS.io has moved to Alpine 3.9. See 903 and 914, between this and the earlier fix for connection dropouts this issue should now be resolved.

🎉

[rudgr]

ah great, will test and let you know ;-)

[rudgr]

Tested and seems to work, Tx! :)
