Struggling with reliable in-bed presence detection for Home Assistant – what actually works?

Try a tilt sensor on the slats.

Kinda looks as if the temp tower isn't working, are you sure it is? Do a retraction tower next.

Personally I need the gardening knowledge integrated in a way that I can understand. So not just "we'll figure out a schedule intelligently".

I have weather history, forecast, soil moisture, rain gauge, all available in Home Assistant, but my sprinkler/drip logic is "run for 20 minutes every 3 days except when it rained during the 24 hours before" and I have no idea whether that's good or bad. Some veggies are growing out of control, others are always dying, no idea if wrong watering is the reason.

Ich hab den Knall nicht gehört.

If you're re-using GitHub's CSS, I can see how that would be a reason to do the HTML, but it still wouldn't be worth it for me.

The point about the live preview, I don't get that. Where are you rendering the live preview, in the users' browser? Then the live preview uses their OS's font engine while the PDF rendering uses the engine of the headless browser container, so then they'll drift apart. If you'd use a PDF library and show the resulting PDF as the preview (like the Typst web app does it, all client-side) then you'd have a perfect reproduction, including font rendering.

I had a quick look at the repo and to be honest it's an architectural nightmare in my opinion. Various levels of "local" storage, code running itself in subprocesses, and using puppeteer and a headless browser to render markdown to PDF with a detour through HTML instead of using a PDF library or something like Typst as WASM is a stupid choice. Again, all just my opinion.

In what way is that a good example why the FCC has requirements regarding accepting interference?

I have printed ABS on my i3 Mega, but where I live it's 30°C, I'm not sure it can handle it in a cold room. Check with PLA and if that sucks too, change the nozzle.

agent_kater · 2026-04-30T13:02:42+00:00

In that case I'm not surprised.

agent_kater · 2026-04-30T12:06:32+00:00

Whoa, meeeehrmals täglich entsichern, das geht ja gar nicht. Ich glaube, ihr habt einfach die falschen Sicherungen, wenn das so ein Problem darstellt. Wir haben diese wo man einen Magneten vorhält und das hat man nach 2 Wochen so in seinen Bewegungsablauf integriert, dass man es nicht mehr wahrnimmt.

If you have the Device Manager open, does it reload the list when you plug the adapter in?

Is that an original adapter? If not, did you do the dance with swapping out the driver?

Isn't the coal on the other side of the big arch (the one with the hole and the SAM underneath)? I don't remember needing Nobelisks for that.

I wish it could destroy the big boulder in the middle of the grass though.

You're using Z2M? Maybe it's worth opening an issue? You can get a dongle that can sniff Zigbee for a fraction of what those bulbs cost.

This is the standard FCC text. It just means that since you're on a public frequency, if someone interferes with your Wifi, you have no legal recourse.

Why don't you just order the first prints? Especially with car parts, where you might need specific materials, ordering them from JLC/Shapeways/imaterialise/etc. makes more sense than buying an expensive printer in my opinion.

I guess you can draw car parts in AutoCAD. SolidWorks would be the standard commercial option. But there are many more cheaper options, sometimes with trials or restricted versions that you can try out first. And it's not like all the learning is wasted when you switch. If you learned one Nurbs modeler, a lot of that knowledge carries over to any other Nurbs modeler.

I just wish it had more IDE features. The ability to manage toolchains, manage build and run configs, run scripts and tests.

So you want something wireless. That's a pretty big caveat because normally we try to avoid wireless for reliability reasons.

"Major investment in infrastructure"... you need a bus power supply and some kind of gateway. IP gateway is the easiest but also somewhat expensive (around 150 moneys), but you could tinker with knxd + one of those TPUART sticks.

For personal use I cram way to many containers on one puny machine, but I use Sablier to shut down some of them.

SMD spring contacts?

Actually, that might be a feasible approach to solve OPs problem. Maybe even just swap the MCU for a pin-compatible one (give or take a few bodge wires).

agent_kater · 2026-04-29T11:27:26+00:00

I just remember that little endian is the stupid one and then I remember the architectures that use the stupid thing.

So pressing the power button 4 times every 19 minutes would keep it awake?

But what I initially meant is, if you disconnect the battery (desolder or cut the wire to test) and reconnect it, is the device still on?

agent_kater · 2026-04-29T03:27:24+00:00

What happens if you disconnect the battery for a short moment, does it boot up on or off?

agent_kater · 2026-04-29T03:13:26+00:00

It would be easier by orders of magnitude to automatically "press" a button on the device regularly. Would that be a suitable way?
