If you were to setup your own “hub” with Z-Wave and zigbee radios running Home Assistant is there any advantage to running on a full blown PC versus a Raspberry Pi?

Best answer
Depends on what you expect "full blown PC" to be. I have everything running on a Pentium J4205 ITX board. Host system is proxmox and each part of my hub is a container image that allows me to easily exchange part. e. g. the zwave to mqtt bridge is openhab, but I might decide to go for openzwave instead, easy task as I can do this while everything else is still running. I have even more stuff running on it such as a NAS distro and pfsense firewall

Processing power?

@

but I guess my question is would that processing power actually be used or just go to waste?

It depends on what you plan on doing. If you are doing simple automations you may not notice a difference but there is a reason many switch from a RaspberryPi to a NUC or PC VM.

But no there is no disadvantage to run it on a pi. SSD is recommended though.

I have HA running on a "full blown PC. " It's running Ubuntu Server 18. 04 headless. HA and Plex run in Docker containers. The PC isn't too special though (1. 8ghz dual core i3, 8gb ram and a 240 gb SSD with attached storage for the Plex lib). Runs well and it's what I had laying around so I put it to work.

There is absolutely no need whatsoever for anything more than a raspberry pie for this kind of application.

I’d imagine you find they work about the same but the pc uses significantly more energy to do that job than a pi.

I moved from a Pi to a NUC. I have a lot of complex rules, InfluxDB, many addons, and OpenHAB is Java. I didn’t like the occasional delays and GC pauses (4GB Pi4 might work well though). It’s super snappy now.

I'm planning on using a pc to run more than just HA. So, in the end, I'd be having a pc running anyways. No need to have a pi too.

Pi vs PC, not much in it. They both have a single PSU and disk (ie single point for failure), although the SD card on Pi will fail sooner. Get a proper server if you need reliability.

For those that are using Home Assistant and Node Red, do you put them on the same raspberry pi or use one for each since they’re so cheap?
