If you have multiple LAN Zigbee controllers, like a ZigStar UZG-01, you can use multiple instances of zigbee2mqtt and hook 'em all into Home Assistant.

Yes, thats true, but that also means multiple zigbee networks.

Goal here would be one zigbee network which is extended to satellite location over TCP.

Thanks! Your question is an interesting one: Forwarding TCP over LoRaWAN seems at first impossible due to large packet sizes (from LoRa perspective!). It turns out there have been some efforts to apply dictionary based compression methods to carry different protocols over LoRaWAN. You might want to check out RFC 8376 for details.

Ah yep.

But I was mainly trying to think how to extend Zigbee-network over TCP (without LoRaWAN).

Currently it seems to be almost impossible.

This is great, thanks for doing this!

I think it is somewhat common situation, when home zigbee network does not reach e.g. garage or some other near-distance building. Usually there is some ethernet/wifi network on the satellite building. So distances what LoRaWAN can reach, are not probably even needed.

Read a bit about the implementation, but I think it is easier to just ask: Could this work over general TCP somehow?

More than that. They're saying that they're running a userspace implementation of both the tcp/ip stack and wireguard. Your machine isn't a peer to the wireguard tunnel, only flyctl is.
dementik · 2 years ago
Of course, your machine can be a peer also. You can create peers to your organization with `flyctl wireguard create`.

Can you buy an EV, that doesn't connect to the internet and is reasonably priced?

I know that is what I am waiting for.

Nissan Leaf with OVMS (disconnected from Nissan Connect services) is something I was happy with.

I have different opinion on Home Assistant. It's surprisingly heavy compared to alternatives, the YAML configs are insanely overcomplicated, they move too fast with Python versions (phasing out 3.9 when it was still the default on the then stable Debian, etc).

My 2 cents go for Zigbee2MQTT, Mosquitton, and Domoticz. Domoticz has it's problems, but it's been a faithful workhorse for me for the past 6 or more years.

Almost all my issues with Python versions went away when starting to use HA in docker container. Everything is very smooth.

One way is also to use HAOS but it is kinda limited.

Current stack for me is HA+traefik+Z2M+Frigate+Mosquitto. All running in containers, on top of Debian. Works perfectly.

It seems like for a basic setup I need:

- an intel-based PC (can be a minipc, doesn't need a powerful CPU)

- a USB Coral TPU ($60)

- some wired PoE cameras (from $60 each)

My question: what do people typically use to power the cameras? A single PoE switch, or multiple PoE injectors?

My Arlo Pro 2 cameras are apparently EOL and might stop receiving free cloud services in a couple of months. So this seems like a good time to upgrade to higher resolution cameras.

(The Frigate docs advise against using Wi-Fi cameras, which would otherwise be my preference.)

dementik · 2 years ago
I am using it all: PoE switch, then couple injectors where it is needed for some specific reason and then also PoE splitters (one cable leaving from PoE switch, going to splitter and then to 4 different PoE cameras, powering everything with one PoE output from switch).

I would not use WiFi cameras. Standard RTSP PoE h264 is the way to go.

I've been using it for continuous recording of my cameras. It would be working flawlessly except for the piss poor firmware of my Reolink cameras firmware causing their rtsp server to choke.

Have you tried Neolink to make Reolink RTSP little better?
dementik commented on Enabling IPv6 support for IPv4-only apps on Linux   blog.apnic.net/2023/06/21... · Posted by u/pabs3
finaard · 2 years ago
Would be interesting to know which applications actually have problems with v6 - the example with directly using a v4 IP is more a user error, not an application issue.

I pretty much stopped submitting patches enabling v6 functionality to various projects back in 2005 as everything I cared about was working at that point. (Side note, I was just trying to search a few of those - but seems that period pretty much doesn't exist in search engine caches anymore. I knew the state of preserving internet history is bad, but I didn't expect it to be _that_ bad)

Colima on mac is struggling with ipv6. Not sure what component is responsible, but I have been unable to connect ipv6 hosts from colima containers.

kragen posted a several of excellent comments highlighting the capabilities of GNU Units a couple of months back, these two in particular:

<https://news.ycombinator.com/item?id=36988917>

<https://news.ycombinator.com/item?id=36995046>

And Trey Harris's "500 mile email" story is what clued me on to GNU units and its capabilities.

Reminder: if you're on MacOS, or one of the BSDs, your default units is from BSD, not the GNU version, and is far less capable. GNU units can be installed on MacOS through Homebrew. The package is "gnu-units", the command is "gunits" once installed.

Edit: Corrected Homebrew package name.

dementik · 2 years ago
Actually,

brew install gnu-units
