You don't have a logging stack? You should set one up, it helps greatly to see your servers long term snd short term status at a glance, especially if you hook it up with grafana to visualize. You can even use grafana with Home Assistant, and do some pretty crazy things with notifications, but i must say, it is a rabbit hole, especially grafana, and quite a large one at that.
I'm currently using grafana with loki and looking to set up notifications with ntfy but if you have the resources you could set up some other logging stacks like elk, or greylog but they're a bit resource hungry and you dont seem to have too many services set up to warrant a larger stack.
Anyway you have a really nice setup, good job!

Really? Because in my private instance, the communities have a lot more users than just 1.
