Zigbee2MQTT needs to be able to read and write to the serial device for
the ConBee II USB controller. I'm not exactly sure what changed, or how
it was able to access it before the recent update.
The _dialout_ group has GID 18 on Fedora.
The Raspberry Pi in the kitchen now has Firefox installed so we can use
it to control Home Assistant. By listing its IP address as a trusted
network, and assigning it a trusted user, it can access the Home
Assistant UI without anyone having to type a password. This is
particularly important since there's no keyboard (not even an on-screen
virtual one).
Moving the `trusted_networks` auth provider _before_ the `homeassistant`
provider changes the login screen to show a "log in as ..." dialog by
default on trusted devices. It does not affect other devices at all,
but it does make the initial login a bit easier on kiosks.
Home Assistant supports unauthenticated access for certain clients using
its _trusted_network_ auth provider. With this configuration, we allow
the desk panel to automatically sign in as the _kiosk_ user, but all
other clients must authenticate normally.
Clients outside the cluster can now communicate with Mosquitto directly
on port 8883 by using its dedicated external IP address. This address
is automatically assigned to the node where Mosquitto is running by
`keepalived`.
This template sensor will be migrated to a helper, since Home Assitant
removed the `forecast` attribute of weather sensors and now requires
calling an action (service) to get those data.
There's obviously a bug or something in `mqttmarionette` because it
occasionally gets "stuck" in a state where it is running but does
not reconnect to the MQTT broker. In such situations, it has to be
restarted (and even then it doesn't shut down correctly but has to
be killed with SIGKILL, usually). I have been doing this manually, but
with this shell script and a corresponding "shell command" integration
in Home Assistant, it can be done automatically. This is similar to
how Home Assistant restarts Mopidy on the living room stereo when it
gets into the same kind of state.
