Thanks for the thought. When pages have incorrect info on the I often stop at that part (why trust the rest of it when there’s an error, huh?)
Anyway I read it all, and it doesn’t help.
I ended up manually setting the friendly name on config (rather than Customize)… But even that does get to the heart of my problem : my switches seem to be recognised randomly as unnamed_x on upgrades on the HA system. So even friendly names end up being randomly assigned to each device.
What I really need is a way to configure them by giving a specific name for the (mac address or other unique I’d) of the switch (ip is no good as they’re DHCP)… Where can I find how to do that ?
Firstly: use your router to assign fixed IP addresses to each device based on MAC address. (good idea to keep a spreadsheet of these for future once your HA system gets big)
