Hello,
I would like to install Home Assistant on the TS-231K, but I don’t know which version I need to choose.
Can someone help with this? Thanks
The NAS only has 1GB of non-expandable memory and is pretty slow, so I would leave it alone.
Which would you recommend?
At minimum, probably a TS-464 (with some extra RAM); however, a common problem is USB adapters (Zigbee, etc.) that apparently need to be manually remounted after every reboot with containers and VMs.
For my own HAss (Home Assistant) installation, I’m currently planning to use a Proxmox server (a Dell machine I snagged cheaply about a year ago). Proxmox has fewer issues with hardware passthrough after a reboot.

Ich habe Home Assistant mithilfe einer virtuellen Maschine aus dem App Center installiert und die OVA-Datei von diesem Link verwendet: Alternative – Home Assistant
Ich nutze es auf einem TVS-872X.
That is a very different NAS than what OP has, also please stick to the language of the subforum!
The TS-464 does exceed the financial budget I had set aside for this.
But thanks anyway, and I learned something new again.
What kind of budget are we talking about? There are also used models without LPC issues.
For example, TS-453B (just checked randomly on eBay)
The idea was to do it on my QNAP, since it’s already there.
But it’s not suitable in terms of performance for a virtual machine, you can’t even install it.
I don’t really need HA, it was just a test to see if I could get it running and what was possible.
What would have been important to me was our new Viessmann heating system (€13,500).
That’s why the budget is tight.
Still, thanks for the help and have a nice evening.
P.S. I’ll ask the top brass what the budget allows. 
The ARM processor in the TS-231K does not allow VMs at all. Only x86/x64 NAS devices can run VMs. While you can run ARM-compatible Docker containers on an ARM NAS, your NAS (as mentioned) doesn’t have expandable memory and with only 1GB it’s already quite limited.
As a NAS, the TS-231K will work, but it won’t do much more than that.
