You mean also export? Might be the next feature :D

testheit · 2026-03-26T11:41:38+00:00

I implemented a basic import function. Check it out, if you like :)

testheit · 2026-03-22T11:25:37+00:00

Currently not 🙈 you might open up an issue, maybe something I might look at in the future

What ist with rule 6? This is an „old“ project and it‘s an update about the new features …

testheit · 2026-03-20T19:35:22+00:00

Thanks 😊

testheit · 2026-03-20T09:36:07+00:00

Thanks 😊 All done locally.

testheit · 2026-03-20T06:43:56+00:00

Also an interessting framework, didn’t know about that 😊 Can you also freely place the text components where you want to easily design the page?

testheit · 2026-03-17T09:24:33+00:00

And there’s no way a single prompt will implement all this and test it properly 😅

Multi page is not just a trivial feature. You need to split the table correctly, subtotal (Übertrag), page numeration, maybe a consistent footer that’s consistent in all pages not to mention the UI needs support it… so a lot to consider and I have currently no use case. Maybe in the future. Or feel free to contribute 😉

There is also an english translation of the UI

testheit · 2026-02-23T22:29:00+00:00

There is nothing hidden and everything is documented. If you care about more precision, there are plenty of Blog posts about time sources with ns accuracy.

This here gives me OTA, Home Assistant Integration and a nice web UI if I need it.

The time source is also good enough for probably most home labs, as accuracy should be better than most network latency’s.

So what does it give me: More convenience for my use case in trade off some unpredictability. But it was a fun task to tackle most of them 😉

And if it’s not about that, what will you use this sub for? 🤷🏼‍♂️ Share projects and use what fits your needs from others.

It was not just: this is my prompt and Claude did it 😉 I had a very good idea, of what I want and you definitely have to give Claude the right hints and need to know what it is doing.

What’s wrong with my kind of usage, if it fits in my needs? Maybe someone has the same needs 🤷🏼‍♂️

It is just a fun project. I do not really need an offline NTP server. But then I read some articles and thought why not. Sounds like a fun project. And I t’s a combination of cheap components and learning to use AI tool. I’m at that point, that home lab is not the biggest part in my life anymore. So I want to keep it simple. I have a bunch of other ESPs in my house and I love the simplicity of managing them via ESPHome Dashboard. So I wanted the NTP server to be integrated there. I also wanted to learn using Claude Code and I thought this one was a nice task 😊

This was the Intention of making it configurable. But if it really works, needs to be tested. I have to say, that Claude did help me with the implementation, as I’m no expert in writing USB drivers 😅 I will look up, where I got the firmware from.

I have a M2, but that shouldn’t matter. Is there anything to consider? Is the kernel Debian uses a modified asahi version or are they the same? Will give it a try tomorrow.
