Home Assistant 0.82.1 error: Error during setup of component zwave

After upgrading to 0.82.1, HA won’t start. I’ve hashed out every bit of config in all my yaml-files, and I still get this error.

2018-11-21 19:49:21 ERROR (MainThread) [homeassistant.setup] Error during setup of component zwave

    use_debug = config[DOMAIN].get(CONF_DEBUG)
KeyError: 'zwave'

Any idea how to fix it?

The error means your configuration.yaml file is missing the zwave: entry. However, that code is from an older version of HA. 0.79.3 is the last version with that exact line of code. Are you certain 0.82.1 is installed and it’s the one running from [*]/.local/lib/python3.6/site-packages/homeassistant?

Aha, doh! I imagine I’ve screwed up my installation, then. Upgrading didn’t reveal any errors as I recall, but running hass - - version confirms your suggestion. Thanks a lot!
