Too soon man

I never said anything about Onyx, I don't own one but have considered them. They look nice and open.
I do own a couple of Kobo devices though and just wanted to say it's not running Android of any kind but it's still relatively open. Especially compared to phones, tablets and Kindle. The firmware/OS point you're trying to make is irrelevant there and I think you know it :)
There is NickelMenu and you can telnet into it. You can also install other OS like KOReader easily, it doesn't have a locked bootloader or anything like that. So imho that's pretty accessible and open.
We are talking about the Kobo right? It's not running any kind of Android or AOSP fork.
No it's not running Android.
Using Calibre you could probably glue that together. I wouldn't want Android on an ereader personally.
It's not open source but it is easily rooted and you can install custom add-ons or even replace the os.
If it's important that it keeps running then it should just be redundant and taking one node down for an update shouldn't be an issue. I know this is wishful thinking for a lot of services but I refuse to be on call for something if the client can't be bothered to make it redundant.
I would recommend getting a Google Takeout export every year or so. Even before it falls off a cliff it's a good idea to have your own backups. Accounts can get blocked, hacked, etc.
Aren't all Hue bulbs Zigbee? They have some WiFi or bluetooth models now I believe but afaik all of them support Zigbee with a bridge.
Found the new thing, looks interesting and will give it a try! Would it be possible to use SSO with a Lemmy account from programming.dev? Sure that would help adoption/usage and additionally support 2FA automatically.
Edit: I see it supports 2FA already in settings. If not possible to SSO with Lemmy then it might be nice to recommend 2FA in the signup flow.
Jealous of the amount of free time you have available ;-) good luck!
