 spacekitteh | sorry i'll have a look this evening | 03:32:03 |
 colonelpanic | are you aware that mrene had already set up a nixos module here https://github.com/NixOS/nixpkgs/pull/332296 | 03:33:43 |
| colonelpanic | Another possibly relevant detail is that I can never view the topology page in the web interface for the border router | 03:37:46 |
| colonelpanic | Also wonder if this warning message in the otbr agent could be relevant: "00:07:33.117 [W] Nat64---------: no mapping found for the IPv4 addres" | 03:45:55 |
 dotlambda | I've decided against blueprints written in Nix for now: https://github.com/NixOS/nixpkgs/pull/377688 | 04:07:16 |
 kdn | After playing with Tuya for a while I want to get started with Home Assistant: got myself HA dongle and a few zigbee-enabled devices. Would you suggest running HA through NixOS or flash RPi4 4GB with their OS? | 13:11:27 |
| kdn | personally I'm more comfortable managing NixOS than whatever distro would be there | 13:11:56 |
 laurynasp | I guess you are asking for a cons vs pros between the two approaches - I am too new to provide such info | 13:57:43 |
| laurynasp | What i can share is that my aim is to have as automated setup as i can, hence I am using nixos to run ha in declarative way, and for that reason i picked raspbery pi 4B because it is most compatible. (I am using 8GB rather than 4GB but that is an orthoganal matter). However, for my journal of automated/scripted/decalrative setup of ha, I have been rather disappoitned, because I was not able to find an easy way to automated onboarding, but that is home-assitant's issue, not nixos modules issue. Still, ha module on nixos on pi 4B is the best i was able discover so far. | 13:57:58 |

 @hexa:lossy.network | 4 vs 8 GB does matter, if you want the rpi to evaluate and rebuild itself | 14:00:23 |

| @hexa:lossy.network | * 4 vs 8 GB does matter, if you want the rpi to evaluate and rebuild itself … aka do automatic upgrades | 14:00:42 |
| laurynasp | Good point! Hexa, if deploymetns are build remotely, i.e.g by running nixos-rebuild --target-host user@$NIXOS_INSTALL_TARGET_IP switch --flake .#ha-rpi --use-remote-sudo on my main machine, would 4GB still be an issue? | 14:03:08 |
| @hexa:lossy.network | probably not | 14:03:26 |
| @hexa:lossy.network | but remember that you need an arm64 builder for that, or do cross builds exclusively | 14:03:46 |
| laurynasp | aha, yet another thing that I forgot to document in my setup - ta | 14:04:33 |
| kdn | right... I forgot that I wanted to set up mac mini for that... | 14:15:08 |
| kdn | would cross-compilation from x86 to rpi4 be significantly longer (I've quite beefy desktop), do you have any materials on how to do that? | 14:16:07 |
| @hexa:lossy.network | I haven't | 14:16:56 |
| laurynasp | Do you mean My main machine is In terms of time, first time might take a while (depending on your config could be 10min or whatever), but redeploymetns usually take seconds to a minute, as long as changes don't require the whole univers to be rebuilt. If it interests you, let me know, and I can share more details | 15:15:06 |
| @hexa:lossy.network | that is not cross, that is emulation | 15:15:27 |
| laurynasp | oh... okay | 15:15:42 |
| laurynasp | whats the difference? | 15:15:53 |
| @hexa:lossy.network | emulation passes native instructions through qemu | 15:16:14 |
| @hexa:lossy.network | cross instructs the compiler to compile for another target | 15:16:25 |
| @hexa:lossy.network | https://wiki.nixos.org/wiki/Cross_Compiling | 15:16:39 |
| laurynasp | I mean, ultimately that does create binaries locally, and once they are copied to pi, the pi can run | 15:16:43 |
| @hexa:lossy.network | setting local and cross systems is the way for that | 15:16:52 |
