In practice, who do you know that’s using it and doesn’t run Arch, by the way?

Well I mostly run Debian, but I do have arch on a machine so maybe I don’t count.

It’s that they’re not designed for non-technical users.

Have to agree there, it takes some effort if you’re setting it up for friends and family.

Xmpp supports group chat, 1:1 messaging, you’ve got webtrc support for voice/video, and its extensible.

Jingle even has screen sharing (and I think a WIP remote control function).

What is missing from xmpp?

Unfortunately the closest I’ve found was this one where the unit on the right on the first page looks like the right model, but it doesn’t say your model specifically unfortunately.

Edit: Well just in case some part numbers match, here is that one: files.catbox.moe/660s6h.pdf

This is only the user manual, but hopefully it helps:

User manual seems to be pretty readily available online, looks like the 51420 and 51220 have the same user manual. Unfortunately I didnt see the service manual in a quick search.

The only hints I did see (and it wasn’t explicit or I would have screenshot it for you) were around under voltage causing it to blink,the door lock not working correctly, and the drain as you mentioned.

So what may be worth checking is that the electrics all have a good physical connection (and if you have a multimeter, even better to verify stable voltage), checking the fuses, and checking that the door lock is operable.

Is there any noise to speak of, like the door lock clicking?
