Home Assistant Migrated from Pi to Proxmox

I just powered down my old Home Assistant server after migrating everything to my Proxmox node.

I’ve been spending far too much time talking to ChatGPT over the past month or so. It started with some simple suggestions for cleaning up the weather dashboard page. It then became clear that I had way more data flowing in than I was making any use of, or even using in several cases.

Eventually ChatGPT taught me the ways of the mushroom-template-card and further still the ways of Visibility triggers with said cards. We’ve even moved into not just reporting the weather, but making predictions based on the data! This is an iterative process, but I am starting to be able to see the numbers reported and know what is going on on the better side of my curtained window.

In all, the weather dashboard went from “Meh, it does the job” to a thing of fricken beauty, based on data. Can it get any better than that?

But all of that beauty, and math, came at a cost. It was starting to be more than a Raspberry Pi 4B (4GB version) could handle. I would need to manually reload a page, as it would just show up as a field of black. Or there would not be enough free memory to be able to recompile an ESP32 image (more on that in a future post). In all, it was just time. I don’t even recall how long I was running that instance. It may have been since before COVID. That is a good, long run. And it was only taken out because I am doing craziness with the weather.

Anyway, the migration was easy enough. I was expecting there to be a “Take 2” this weekend, but it is all complete. The toughest part was waiting for the fresh backup file from the Pi to populate the into the new instance on Proxmox. That took about an hour.

I need to get serious about repointing the backups from the Synology NAS to the UnRAID server (oh yeah! I did that, too!). It is taking a very long time to migrate off of the Synology.

PS: I just saw that the Home Assistant VM was already hitting 93% usage of 4GB of memory, so I upped it to 8GB and restarted. Never could have done that with the Pi!
