Recomend a Mini PC to host home assistant on

must not add insane amounts of cost to my power bill
Has to be upgradable if I need to add upgrades to the hardware in the future
Has a speaker
may want to possibly also set up node red but it depends on if I need it or not because I may just be fine with home assistants automation
has to have wireless connectivity
mainly setting this up to add automation around my reolink cameras linked through the reolink home hub for example getting a second camera in the same area to start recording when one detects motion or link other smart home security products like sirens or floodlights

Just go with a Raspberry Pi 4. You don't need much compute power to run HA.
- The downside is price, they're quite expensive after buying the Pi, storage, power supply, and maybe a case.
- Bare in mind that Home Assistant will wear SD cards very quickly, if you do get a SBC make sure that you boot from a SSD or something.
  
  Yeah, I have mine on an odroid nu2 which uses an emmc
If you want really cheap and low power, a Raspberry Pi will do for most tasks.
If you want more processing power, an old Thinkpad laptop is reliable and has a built-in UPS (a laptop battery).
Any desktop computer will give you the customisation and upgradability you want, but you'll need to decide on each part individually. I don't have any specific recommendations here.
- Eh, RPI pushes you to use a microSD card which sucks in a few ways. They also aren’t all that cheap.
  Used thin client is the way to go
  
  You can leave just the /boot partition in the SD and put the root fs in an external USB drive (SSD or mechanical).
  I’have a SIMH emulation farm running inside a Pi3 which has been up literally for years. Zero trouble.
  
  @traches
  I completely agree. I started off using a rpi as this whole home automation thing was more of a test at first. Then the more I used it, the more I relied on it and it really bugged me when my sdcard failed and I could not restore the backup as well. I moved away from rpis for this and for anything of real importance ever since.

- NUCs on AliExpress with an N100 intel cpu cost about as much as a Raspberry Pi and are more powerful and you get SSD storage so non of the downsides of SD cards.
- They are dropping support for 32bit computers, so be careful not to buy rpi2.
I grabbed a cheap Dell Wyze from eBay, then stuck proxmox on it, then Home Assistant in a VM. Works beautifully, plus I can run other VMs and containers. Plus snapshots etc. It runs at 5w idle and 15w under load.
- @theboxhead @x4740N Are you running all your apps independently on Proxmox or are you using a framework to bring them together? (Like #Yunohost or #coopcloud) - I have been running Yunohost on a VPS but moving to #Proxmox on DellMini - I am still getting my head around Proxmox but like the idea of knitting apps like HomeAssistant, Nextcloud etc with LDAP/Oauth, Email, DNS and ReverseProxy, Backup - all the underlying stuff that keeps your environment running.
  
  I’m just running them independently. Although the proxmox helper scripts automate the creation of a load of bits that I use. https://community-scripts.github.io/ProxmoxVE/
  I don’t run much, just a Debian-vm, Unifi docker, Jellyfin and Jellyseer (and some *arr) apps.
I recently picked up a GMKtec NUC for around $100 off of AliExpress. It uses very little power and is very powerful for the price.
It doesn't have a speaker and the opportunities for upgrades are a bit limited, but otherwise I think it might be suitable for you.
I run it as a media server at home without any issues at all
- I second this. Bought one one of their N150 units recently from Amazon. Replaced the Win11 it came with and installed Proxmox, and it's blown me away what I've been able to do with it.
  It's currently running HAOS (with ZBT-1 and Voice Preview) and a Linux VM, and plan to do more.
- Yep I second this. If have a GMKtec NUC with HA on it and it runs perfectly.
I've not used this, so I can't promise anything, but I bookmarked it from another thread. Maybe it has some pertinent info?

I use a 2nd hand thin client from lenovo.
I love the Dell micros.

8th gen i5s, 6 cores, very low energy usage and holds 64gb RAM. 2.5gbe for another ten bucks and i think they cost me 115 each in a lot of 5. Picked the nicest three and resold the other two. Leftover 250gb ssd for os and a 1tb nvme for localdisk. Proxmox backup server on one as well.
EDIT: I'm running proxmox with a Home Assistant VM and USB hardware passed through to clarify.
- I have the same bluetooth keyboard. lol
  
  It's my utility keyboard lol. My keychron is hooked up to a kvm vm and I adore that thing but having a nice kb/touchpad on hand is awesome.
Any reason not to just buy a Home Assistant Green?

Edit
I just saw that you want something upgradable.
Got myself an ASUS NUC 13th gen with an i7, have roughly 20+ docker applications running on a headless Debian 13 VM with 7 cores allocated - Proxmox as the host.
Small, quiet and powerful.
These don't have a speaker AFAIK but they do have 3.5mm out so adding one would be trivial:
https://www.amazon.com.au/GMKtec-Upgraded-Desktop-Computer-Business/dp/B0F7XRLRM6
They idle around 10W according to a review by Jeff Geerling. That's on Win11 though, I'd imagine Home Assistant OS is a little bit less. As for upgrades, the CPU isn't socketed, but it uses standard laptop SODIMMs, and a full-size M.2 slot. You aren't going to find socketed CPUs until you move up to a mini-ITX computer, like a Dell Optiplex USFF, but those do eat a decent bit more power, maybe 20-30W idle. It Has WiFi 6 and would easily handle multiple addons like Node RED.
Edit: Oh yeah, it has a 2242 SATA M.2 slot as well, so you can add some cheaper, slower storage as well as the 512GB NVMe boot drive if you wanted.
@x4740N
8th gen Intel Lenovo M720q or M920q. Put proxmox on it and run HA as a VM. Plenty of vids and articles about this little guy.
Has a speaker, is probably the biggest sticking point, something arm based like a raspberry pi or equivalent will hit the power requirements.
What's an "insane" price?
I love þese Trigkeys. $219 for a Ryzen 5, 500GB NVMe, 16GB, WiFi 6, and 12 threads. Fanless. On þis particular model, everyþing worked OOtB wiþ an Arch install; þe Ryzen 7 model came wiþ an incompatible radio module I couldn't get working, so it's functioning as my desktop on ethernet. Þe 7 also needs a fan, so it's not as nice for node server service.
Decent looking, super easy to open and replace memory, M.2, and even þe WiFi module, if I needed to. Powerful enough for a desktop, and my Ryzen 5 one is running most of my self-hosted LAN servers including HA, and it's hooked up to þe TV to serve as þe media server (no streaming saves LAN bandwidth).
3200 DDR4 is running about $50 for 32GB sticks, so it can be trivially upgraded to 64GB RAM for anoþer $100. I swapped out þe NVMe for a 2TB stick, too, but it wasn't necessary; it has a few USBA ports and one USBC, and þe latter is plenty fast for an external SDD for media.
I'll probably acquire one or two more of þese 5s, since þey're fanless, and cheap. I've been super happy wiþ þe two Trigkeys I have. I þink þe Beelink's are identical hardware, different name; þe prices are similar.
Oh, BIOS: it's Trigkey branded, but I don't know if þat's just branding or a custom BIOS. I haven't tried replacing it wiþ a FOSS BIOS yet.
- What the hell happened to your "th"?
  
  He's doing it in an attempt to "sabotage" AI training.
  It's also a useful flag to indicate that he doesn't understand how AIs are trained.
- @Sxan @x4740N In the video on the amazon website it mentions a fan 🤔
  
  Þe Ryzen 5 doesn't; þe 7 does.
  But now I've become unsure. I'd have to open it to be sure. Þe information on Amazon (oþer þan þe specs) is not very reliable. Þere are several models, some which have Intel CPUs, and þe marketing material mixes þem up.
  But, like I said, I'd have to open it again; it's been a while. I don't remember a fan in it, þough.
