Anyone know if a #RaspberryPi 3 is powerful enough to host #HomeAssistant?
@recantha if it is 2B, then even more so 3, but it all depends on what exactly will be used
@rocking_horse I'm just thinking as a hub for the different switches and hopefully a camera around the house?
@recantha running my HA on a Pi3. Had to add a reboot automation every 24h because after installing zigbee2mqtt it would crash after 2 days. Also disable passive BT-scanning and use ethernet (mine sometimes won't reconnect to the *very* close AP after a reboot). Updates are *slow* and I doubt it can handle multiple camera feeds, but I don't need that.
@recantha I started with the original 3, but as you add more services and devices it quickly gets too slow. Too little RAM.
Also, running from a microsd card will eventually kill the card due to a lot of writes.
Moved to 4 with 4GB RAM and a fast high quality USB stick and it's been working really well.
@recantha Afair #homeassistant stopped shipping 32bit versions last year.
@recantha I would not recommend that. Also I would not recommend SD storage
@web_martin Okey dokey. Might see if I can get the Pi 5 running Pi Hole to host it as well, then.
@recantha @web_martin If you already have a Pi3 why not use it for PiHole and the Pi5 for HA?
I have the same setup here with a SSD for the Pi5
@chaosflo @web_martin Ahhh. Not a bad idea, that. Use the weaker machine for the less intensive job. Good call. :-)
@recantha @web_martin I use the Pi3 only for PiHole because it is a Single Point of Failure. I don't want any other service to impact it.
@recantha will run. but would not recommend it. use a cheap x86-64 device with proper storage (no sd like it is the default wie rpi). will save you some problems down the road.
@recantha I’ve been running mine on a Pi3 for years. Works fine
@recantha but as others have said - with an external SSD
@recantha all that said. Triggered by this thread, today I changed to a 4B that I had sitting around. It is definitely faster and doesn’t seem to choke up as often. More RAM, etc definitely makes a difference

@recantha It is. But only for a simple home. If you need more go for a Pi 4 or Mini PC.

But you can try with the Pi 3 and if it's not enough, the backup restore process is extremely easy.

@kaiserkiwi Cool. I've got a couple of Pi 4s hanging around so might move to that instead.
@recantha a pizero2w would also probably do the job (it is basicly a 3b+ with reduced ram)
@recantha Running HA OS baremetal on a Pi4 with 8GB RAM. Memory use is fairly light, so 8GB is probably overkill. Also running off an SSD drive (via USB/SATA adapter) to avoid memory wear issues with Micro SD cards. #homeassistant #raspberrypi
@ray Cool. So I'm on the right lines. Ta. :-)
@ray @recantha that's a serious heatsink. Have you any temp figures before using that? I have a similar setup, minus huge heatsink, and its running at about 42°. Granted I have it in an enclosure, but if there was a silent option like that I'd consider it. The fan in the enclosure is very loud when on.
@ropatrick @recantha It's actually a heatsink on top of a heatsink-type enclosure. The larger one (bare aluminium) lowers the Pi temperature by few degrees, maybe 3 or 4C tops. It's not really necessary, but I had it on hand... I was looking for a fanless solution. There is also a thin thermal pad underneath that large heatsink. If you zoom in you can see it. I also have popsicle-sticks underneath it to encourage a bit more air circulation around the bottom.
@ray @recantha nice, I saw the sticks alright, good idea. I must tinker again and see if I can shave off some °s.
@recantha
For a basic config it’s good enough, a USB stick is not expensive. Updates take some time but basic automations work well.
@recantha the results of a google search suggest there are people who know
