I have further questions.. - the device page specifies: "USB: 1 × USB 2.0 (maintenance use only)" - How does that square with the need to connect a Zigbee/Thread radio to the HA instance? - I currently have the (USB only) Sonoff Dongle Plus MG24... I am aware of the Sonoff Dongle MAX which can connect via ethernet/wifi, so I guess that could solve that one... But the next one isn't so simple: "Storage: Pre-programmed micro SD card (included)" I'm really wary of SD for the write-heavy load of HA's recorder database, and the subsequent wear on the SD card... - is there any way at all to utilise the PCIe hardware which does exist on the CM4 to connect (say) an NVMe SSD via the appropriate HAT??

Or.. how about, a free-tier cloud option like (say) Oracle Cloud's perpetually-free ARM instance running MariaDB, joined to my tailnet, to provide a shared, professionally hosted, always-on database as the target for the recorder database instead of any local storage? - anyone tried that?
Thoughts??

That was a mistake. USB is not just for maintenance, y into the USB you can plug the dongles into the usb port.
SD card is prone to corruptiom due to frequent writes. However our application minimised writes to the CD card - the logs are writtent to RAM, so most of the problems dsue to this should not occur. we also minitor the SD card wear and reprt ifd there is a problem. Howeverf that remiins to be proven over time
you can plug in the SSD into the USB and follow the steps
1. Plug the SSD into the free USB port (powered enclosure or low-draw NVMe/mSATA — that port is 500 mA USB 2.0).
2. Settings → System → Storage — the new disk shows up there.
3. Press Move data disk and pick it.
4. It reboots itself; config, add-ons and backups now live on the SSD.
However you need the SD crad to start
I have not tried the free cloud option to store the database. if that is a backup option, ithere should be no problem
Excellent news, thanks for the update... just to be clear, - there is just the single USB yes? - I like the USB storage option... I do already have an NVMe disk in a USB enclosure... - but will it be OK to connect via a (powered) USB2 hub? - I'd only have 2 devices - the NVMe disk, and the Sonoff radio.... hopefully a decent quality, powered hub would avoid the 0.5A capacity limit on the onboard port... and hopefully the hub wouldn't intoduce latency to the radio signals...
That being the case, this really is a no-brainer for me, and I'll be ordering TWO of them! :-)
