What nice feedback to read. I think you and I are aligned in what this will hopefully become. I really just wanted to start publicly sharing my hobby notes instead of holing them up in a local Joplin file or something, so that's what I'm going to do. We may have similar hobbies though, which sounds like it'll benefit you. Haha.
For anyone who reads this post and sees the mention of headscale -- that was the overarching goal here but the blog post started getting long so I decided to chunk it up. As soon as I polish up the headscale writeup I've got drafted and get that posted, I'll drop a link here just in case anyone is interested.
No one has mentioned anything about how CISA -- as gutted as they are -- has stepped up to ensure funding for the next 11 months. CVEs aren't going anywhere.
I use an Amcrest AD-410 for this and it works great. Video is ingested by frigate, and I am using a fork of amcrest2mqtt to monitor for button pushes and receive a notification on my phone. They also have a "chime kit" I think it's called, to hook up to your 24v doorbell unit.
It's just an NTP pool. The device is trying to update it's time. Likely it made many other requests to other servers when this one didn't work.
Maintaining up to date lists of anything is a game of whack a mole, so you're always going to get weird results.
If you're actually unsure, pcap the traffic on your pfsense box and see for yourself. NTP is an unencrypted protocol, so tshark or Wireshark will have no problem telling you all about it.
That said, I'd still agree with the other poster about local integration with home assistant and just block that sucker from the Internet.
Ran into a similar conundrum. We use mealie for recipe management and occasionally meal planning, but the shopping list is clunky. We resorted to just making a list on a card in Planks. Not purpose-built, but it has worked rather well for us.
This is absolutely not what DNSSEC is. DNSSEC provides authenticity of the response, not privacy. You're describing a means of encrypted name resolution, like dns-over-tls, dns-over-https, etc.
Ah yes, those examples were helpful and definitely helped inspire this. Glad you found some value in the ramblings. Post 2 will be up soon.
