@Egyras You could figure out a is_pifive_8gb() function that return 0 on 8gb Pi5 only but 1 on Pi5 with less RAM.
See /opt/openhabian/functions/helpers.bash there's is_pifour() is_pifour_8gb() and is_pifive() as templates

RPi5 8GB

@mstormi how to call(execute) these functions in right way for checks ? From where you pass variable "$hw" ?

@mstormi may this help you (pi5_8GB):

openhab:~ $ grep "^Revision" /proc/cpuinfo
Revision : d04170

openhab:~ $ grep "^Revision\s*:\s*[ 123][0-9a-fA-F][0-9a-fA-F][0-9a-fA-F]17[0-9a-fA-F]$" /proc/cpuinfo;echo $?
Revision : d04170
0

openhab:~ $ totalMemory="$(awk '/MemTotal/ {print $2}' /proc/meminfo)";echo $totalMemory
8246848

@barns-do did you tried to install pre-release openHABian v1.9, for me seems wifi (settings for this exists) dont want to work as getting error with comitup. Didnt tested LAN yet as kids sleeping where monitor and can plug cable.
Failed to start comitup.service - Comitup Wifi Managament.

@mstormi here is first-boot.log for RPi5 8GB connected via LAN with openHABian v1.9
first-boot.log

[Egyras]

seem for WIFI in Raspberry Pi OS 12 'Bookworm' they dont use anymore wpa_supplicant.conf, instead this is used nmcli So this explain issues with WIFI on first boot.

[mstormi]

Try the comitup hotspot, please.

[Egyras]

Try the comitup hotspot, please.

doesnt work, tried to connect but phone deosnt show it....

[barns-do]

@Egyras: I just installed V1.9 LAN-based. At first glance there are no problems with it. No WLAN-Testing ...

[Egyras]

made a new image via Raspberry Pi Imager and defined WIFI settings there, all went without any problems.

[mstormi]

Imager will get you an old image.

So seems RPi5 is supported but WiFi does not work yet. Continue in #1823
