Intégration/add-on in home-assistant or standalone?

I am running home-assistant supervisor on a Linux (Debian 10) home server.

I know that anything else than the standard is not official. .

There is some tools like influxdb and grafana, that I am wondering if I should install throw home-assistant integration or directly in the server as a standalone software.

Thank you

as an addon.

Thank you. But will I get everything else available for it also ? Anything thing I want to add to influx ?

Your installation will become unsupported if you install external software.

AFAIK the addons are feature complete.

One limitation I know of:

For the Grafana addon you can only install official plugins posted on the Grafana website. Plugins from github are not possible.
