All you need to do is make sure they have different hostnames and it works fine.
Yeah, I havenāt got much in the way of automation yet, just been playing with it for a while until I figure out how I want to run it full time
sorry complete novice here
can Pi 5 run hAOS yet as i have just bought a pi5 with the NVMe Base for Raspberry Pi 5 ā NVMe Base and the cooler.
I have pi so on the sd card and the pi4 version of HAOS on the NVME but im getting a not supported error on boot when tring to boot off the NVME.
Is there a way to run it yet?
Sorry for any spelling mistakes Iām Special
there are a few of us with the same issue, welcome to the āspecialsā

Please do not try running the RPi 4 version of HAOS on the PI 5. That will definitely not work. If you are using the official Raspberry Pi Imager tool, youāll still need to manually download the HAOS image that has been released for the RPi 5, and then select it using the option below.
For now, this definitely works if you boot the RPi 5 off of a microSD memory card, or a USB 3 connected NVME drive. I have not yet seen any successful reports of anyone booting HAOS on a RPi 5 using an NVME hat (i.e. PCI Express connected NVME).
Update: Looks like some users have reported that they can successfully boot HAOS directly off of a PCIE connected NVME drive! This is good news. I have seen some reports that not all NVME drives are compatible with the RPi 5. Do some research before purchasing.

It worked and is running
however new issue and this might just be me not understanding how it works properly
HAOS is running. can I get the GUI up from the ha > command line?
sorry real novice

No. HAOS is designed as a headless server. One must use a web browser to configure and manage the platform. The HA Mobile Phone app is also an option. Both work very well.
can you put a head on it?
noā¦ as ogiewon said, itās all controlled form the web browser or mobile app.
Why would you run anything from SD card with a NVMe hat? Surely the point is you use the NVMe entirely.
I did not the nvme works fine through the pcie
you have to change it to gen 3
so load the pi OS on the sd then and change the setting but works fine.
Hi, have same problem today. with 11.5 rc3 - while connected to USB 2.0 port - HA working good. When connect to USB 3.0 - shows errors on boot, starting with errors with Docker containers.
I donāt understand why you would want to connect over the USB now the Pi5 has PCIE support. Get yourself a NVMe hat and boot directly from that. Super fast and stable.
Just curiousā¦ Are you personally running HAOS on a RPi 5 booting from a PCIE connected NVME drive? If so, what version of HAOS are you running?
Previous attempts, noted earlier in this thread, were unsuccessful in doing so. Thus, my curiosity if youāve achieved with this hardware combination. If yes, please let us know which NVME Hat youāre using, as well as which NVME drive.
Thanks!
Update: Sorry for not searching this thread more thoroughly before I asked the above question. Still curious thoughā¦ Are your running HAOS on this combination? If yes, what version? If not, what OS are you running on your RPi 5?
I had HAS running on my Raspberry 5, however, with my ZWAVE Stick 7 it crashed over and over, returned back to the 4 where everything is running succesfull on, hope the zwave issue on the Raspberry 5 will be fixed, then I move over. without Zwave, what I have seen from the RASP 5 is great, what a perfect and fast performance.
If you have a problem installing HAOS on Pi 5 with USB 3.0 SSD, you can check this video: https://youtu.be/8VkQteJ1Yf8
And this is a video about how to install HAOS on Pi 5 with an SD card: https://youtu.be/0iB-5omg-Io
Iām also still running this version on my RPI5 11.4.dev20240108 I donāt dare to update it to 11.4
Yes I am running HAOS.
There is a document (Forward guidance - Raspberry Pi Compute Module 5 - Modules - Product Information Portal - Raspberry Pi) which describes the pin layout of the CM5. Itās under NDA and I have not found any confirmation that the pin layout is backwards compatible with the CM4. I hope it is, but Iām worried that itās not so simple because there is no confirmation about backwards compatibility.
