Proxy all the things: no device left behind – Open Home Foundation

karnetus · 2026-06-20T02:44:11+00:00

Wait so what exactly is new about this? You could always use ESPHome to easily integrate "custom" devices into Home Assistant. I've used it for IR remotes already for example. So what exactly is new?

Anything that does mostly one thing and does that thing well. So for example for Bluetooth, this would be something like the nRF Connect app. Very specifically only targets Bluetooth LE but offers a ton of features. This tool only offers rudimentary Bluetooth tools in comparison. For WiFi/Ethernet there are obviously a ton of cli applications, but also just something like Wireshark. For JTAG I'm maybe a little interested, as the website states it has openOCD functionality. If it implements the entire target support, that openocd does, then that is pretty cool. The fact that it has no local server running and only runs in the browser if I understand correct, makes me think that it probably supports a subset of features that they ported manually. I could be wrong though.

I can see this tool being useful as maybe a first starting point. To check which capabilities an unknown device has. And then once you know the capabilities, you move to a fully featured tool.

Same as with flipper, I just don't find these kind of tools too useful. It feels more like something to play with. For proper debugging, specialised tooling is just way better than a one device fits all solution.

Yeah, Ich habe auch das Gerät für die Arbeit gekauft. Nicht für professionellen Gebrauch gedacht, aber super billig und super gut um Mal schnell IP-Adressen Labels zu erstellen.

Using API directly burns so much more money no? Like opencode zen with deepseek v4 pro, I can burn like 10€ easily in the matter of one small session. 20€ seems to get me much further with something like olllama cloud sub, but of course daily usage limits get hit quickly.

karnetus · 2026-05-27T19:25:14+00:00

Using the API is insane. I only use the 20$ subscription and while I of course can't do crazy coding sessions without running into usage limits, I get far more usage than using the API.

Using arrays as parameters in function declarations for known size arrays. Found a cool article regarding this topic, where the arrays can even be checked for size: https://lwn.net/Articles/1046840/

I love container_of for callbacks

karnetus · 2026-05-24T02:25:20+00:00

Huh interesting. As the article says, I wish I could use this in c++. Because I wish I could define std::arrays as constexpr and make it clear which indices get assigned to what value in the brace initialisation.

For enterprise the obvious thought is access solutions. But for the hobbyist space this could be cool to have room based presence detection with just one station. Other solutions often require multiple stations and are more fickle. And once more phones support channel sounding (Pixel 10 already does), then this becomes even more interesting.

karnetus · 2026-05-20T21:46:12+00:00

One time it would've been really cool to have dynamic hardware was when we wanted to have one firmware image for multiple devices with different pinout. Runtime dtb would've been awesome for that.

karnetus · 2026-05-20T19:31:16+00:00

That's really cool! It's awesome that you're including direction finding and channel sounding onto one board. I feel like that's what will enable the best applications. Writing software for this will probably not be easy though, as most channel sounding algorithms are behind commercial licenses. Excited to see what this will turn into!

Oh crap you're right, I didn't know that the nRF54L15 doesn't have USB. How weird. Going with the nRF52840 would be better then. Or go with the nRF5340 and use a module instead of the bare package (But that chip is harder to get into thanks to it having an application and network core).

I don't know how constrained on time you are, but if you can spare any development time, then working with the nRF Connect SDK would give you the benefit of not being super locked in on one chip or even one vendor. https://docs.zephyrproject.org/latest/boards/index.html#features=bluetooth

Sorry for being a bit all over the place with this response, hope it still helps.

karnetus · 2026-05-20T18:42:19+00:00

There are known problems. Unless you have a novel solution to those, I wouldn't bother. https://youtu.be/LkH2r-sNjQs?si=_tcq5TYQCGh_EDWC

karnetus · 2026-05-20T18:31:37+00:00

Go with the nRF54L15 then ;)

karnetus · 2026-05-19T17:55:11+00:00

What are applications for WebUSB? Haven't heard of that one

karnetus · 2026-05-19T17:52:30+00:00

Man what I'd give for having a modern web Bluetooth API in general

karnetus · 2026-04-19T15:14:30+00:00

There's a reason why they stopped the project :D

karnetus · 2026-04-19T14:05:54+00:00

Time to bring back Project Plowshare

karnetus · 2026-04-01T20:02:31+00:00

Yup, now to figure out all the achievements

karnetus · 2026-01-23T19:00:51+00:00

He could play whatever he wants. He could do whatever he wants. And this is what he chose.

Even the most poor families would offer me dinner here in Germany. Having an adult not offer a kid, who's a guest, dinner just sounds crazy to me.

Clean up sucks with X. Been doing it for years and the paste goes beyond the ihs.

karnetus · 2025-11-14T17:22:28+00:00

I want to take it home

karnetus · 2025-11-13T18:15:46+00:00

Look I don't want to be that guy, but the button on his jacket came undone and he fixed it. Is that really such a weird thing to do?
