I moved my Home Assistant from Proxmox VM to a older Lenovo Laptop we had stored as we thought the charger wasn’t working. We are preparing to move so it was my job to check that laptop as well as 2 others. 2 I am not going to use and e-scrap those later this week after yanking the drives out (I don’t trust anyone with my old drives). It turned out, the charger works just fine! I just installed it early in the morning (Midnight) and so far, it seems just as responsive if maybe more than what I had on the Proxmox host so that’s a win on my end. Plus, I was able to give it the full 8gb of RAM it has instead of the 4gb I gave it in Promxox and somehow it’s showing lighter use than what I had in the VM. 2.8gb vs. 4-5gb it reported from the Home Assistant Hardware details when in the VM.
For Home Assistant, I use the installation script from here, it works flawlessly:

This group took over the project after the main developer passed on, they are quite easy to install and just need you to be in the Proxmox host shell (Once you install it, you will know where it is) :)
