I've created a _Pool Time_ calendar in Nextcloud that we can use to
mark when people are expected to be in the pool. Using this, we can
configure the "someone is in the pool" alert not to fire during times
when we know people will be in the pool. This will make it much less
annoying on HLC pool days.
The digital photo frame in the kitchen is powered by a server service,
which exposes a minimal HTTP API. Using this API, we can e.g. advance
or backtrack the displayed photo. Exposing `rest_command` services
for these operations allows us to add buttons to dashboards to control
the frame.
Editing `configuration.yaml` et al. using `vi` via `kubectl exec` is
rather tedious, since the version of `vi` in the *home-assistant*
container image is very rudimentary. Thus, I think it would be better
to use a ConfigMap to store the manually-edited YAML files, so I can
edit them with my regular editor on my desktop. For this to work, the
ConfigMap has to be mounted as a directory rather than as individual
files (using `subPath`), as otherwise the pod would have to be restarted
every time one of the files is updated.
