Thanks. I saw those although they seem to be reliant on the Nanoleaf app. But a good option for some I think.
I had a look in my keychain - no thread network credential there.
This is it! I followed those steps and now have my network’s TLV. Not sure why I wasn’t able to find this documented anywhere (or just available in the Thread integration!) but at least I’ve got it.
There are two credentials shown (which says “Apple Keychain” @najal!) which have a “Transfer to Home Assistant” button that I’m not brave enough to press. Can I figure out which devices they relate to with the Border Agent ID? I’m guessing they map to my Homepod mini and AppleTV. If I hit transfer I assume that puts HA in control… but I also would guess my HomeKit side would get upset
