Or would it be better to split it up on multiple devices? Or maybe just upgrade to a single RPi4 or 5 mod. B?
I think it’s possible to run everything in the same RPi 3b, however I think it will not be smooth, cause there is only 1GB of ram available…
I think the best is one device for each service, however I know that sometime we can’t afford that, so I think you need at least 1 device for Pi-Hole and Octoprint, and another to the Home Assistant
Thanks for the answer!
Definitely agree they should be split up if possible. Octoprint and Home Assistant are both rather demanding on a Pi, particularly the Pi 3B.
I would however opt to run Pi-Hole on the Home Assistant device as there is a plugin built in for it, and Home Assistant is the kind of thing you would be more likely to leave on at all times.
Just as a tangent, definitely get an SSD for whatever device is running HomeAssistant and set it as the boot drive as the constant writes will cause your SD card to explode in a huge fireball after not too long.
