I have a few questions surrounding HA Yellow. I’m looking to do the following based on assumptions which I will also detail.
HA Yellow w PoE - 0GB eMMC, 8GB RAM, no Wireless, I will flash the Yellow HA OS onto and NVME. My first assumption is that I do not need wireless as it will be connnected via ethernet and Zigbee, Thread, Matter will still work - is this correct?
My second assumption is that as I have (or will) flash an NVME with HA OS then I don’t actually need any onboard eMMC - is this correct?
Apologies if these are obvious but I can’t seem to find confirmation of my assumptions anywhere.
As long as you connect the LAN port (PoE, Duh!), and any wireless devices you have can connect via separate WLAN APs - AOK.
Matter usually uses Ethernet (e.g. WLAN); most Thread Border Routers connect WLAN<=>Thread (e.g. Nest Hub Max, some Alexa (ISTR), some Apple hubs, etc).
I’d probably do the same with a CM5 if they were available. The only reason to go for eMMC + WLAN is to make a future re-use of the CM4 more flexible as the cost difference is buttons.
My CM4 Yellow works OK with 2Mb, but complex ESPhome projects can fail (set single threaded) - I’d probably go for 4GB+.
HAOS was recently changed to install both OS + HA onto the NVMe and ignore the eMMC - the rational is to make upgrading from a CM4 to a CM5 easier (just move the NVMe over…).
A CM4 is easier to install as apparently the CM5 won’t boot from USB directly - not tried yet.
My Yellow has the original install so the OS is on the eMMC, and did the “Move Data Disk” thing to get data on the NVMe.
Great thank you for replying and sharing! So my assumptions are sound but I just needed that confirmation. I run a Unifi network with APs so no wireless is the way to go for me. I’m not too bothered about future use as this will be gathering dust squirreled away in a rack for years to come. I just now need to wait for CM5 and Yellow PoE stock! No small feat.
