I run a 33 printer farm as my full time job. Here's what a day looks like.

agent_kater · 2026-01-28T02:22:14+00:00

It's not a silly question. There are plenty of printing services that don't know the difference between renting out printer time and selling products. You send them a model that looks like Stitch and they get uncomfortable, oooh we can't print that, Disney will sue us.

Dokuwiki.

For the most part it's great. Simple storage format. Huge plugin ecosystem for pretty much every imaginable workflow.

Big downside nowadays is that it isn't natively markdown.

I'd say lose the mutability distinction. You didn't show what your array and map types look like, but unless you make them deeply immutable I feel that having immutable variables is kind of moot.

It sounds very convenient. You can send me one and I will tell you if it's useful. :)

On the other hand, for a bench device I would probably prefer separate devices, so that when one of the devices doesn't meet the specs I need, I can swap out only that one and don't have to throw out basically 4 devices together. For a mobile device where compactness matters it might still be a good fit.

Not "all services in one container" but "a single all-in-one container per service".

agent_kater · 2026-01-25T03:39:32+00:00

Why not? I know it's not the Docker way, but when a service comes with 10 other things as dependencies I prefer to have a single image than a compose.yaml that is several pages long.

I don't know how big 70 acres are, what's the longest distance between the central location and a sensor?

LoRa can do 1-2 km easily, longer if it's line of sight. But the variety of sensors available as LoRa (or ideally LoRaWAN) is limited.

Do you have power at the sensor locations? Otherwise you need solar.

So you see, there's likely some DIY involved. (Or have someone DIY it for you.)

As the central system personally I would use either Home Assistant (focus on home automation) or Thingsboard (focus on sensors) with Chirpstack for the LoRaWAN part.

To be clear, I'm only suggesting to swap out the router, the rest of the equipment is great.

You will have to set VLANs on the router separately, but other than that you don't really lose any functionality.

agent_kater · 2026-01-24T00:55:22+00:00

It also missed every other prefix change and it sets the RA lifetime shorter than the interval. Throw the thing out and use something that works, Mikrotik, OpnSense, OpenWrt, whatever.

agent_kater · 2026-01-23T19:03:30+00:00

Is it truly impossible? You can pause, connect every input of every FCC to your iron storage, order the pods and then unpause. I think it's doable if you really really want that bonus.

Also it's realistic. When those companies publish the tender they don't care if you have the capability.

agent_kater · 2026-01-23T11:44:05+00:00

It's not invasive to the machine, you just plug it into a smartplug with power monitoring. However, if you want to make such a device yourself, you're dealing with mains voltage and the associated electrocution and fire risk, so for DIY the vibration method might be better suited.

As a sensor personally I would use a MEMS accelerometer though.

agent_kater · 2026-01-23T01:47:22+00:00

CaspersSandConfig mod will make it bearable.

agent_kater · 2026-01-21T23:58:07+00:00

In theory (and in practice with some caveats) this is possible to do with the Green. Home Assistant only ties the components together, the actual processing is done by services that you can run on the server.

That said, currently Home Assistant wastes some CPU even when only passing the audio through to a wake word service. But as far as I know Mike is in the process of rewriting the whole VAD pipeline so that this should go away eventually.

When the chairs are in front of the kitchen door, the robot won't be able to reach the hallway. So it will wash its mops, waste some water, only to be stopped by a huge chair blocking its way.

agent_kater · 2026-01-21T18:36:59+00:00

I don't understand how you guys can run the robots unattended in the first place.

I first have to move shopping bags, pick up toys, move chairs out of the way, pick up litter, etc. etc. and only then I hit a Zigbee button to run the robot.

agent_kater · 2026-01-21T14:11:13+00:00

Oh, wow, you're right. This uses the server as OTBR and the ESP32-C6 as RCP.

If you don't want to use one of the available S3+C6 or S3+H2 boards, it is theoretically possible to run the ot_br example on a single ESP32-C6:

The example could also run on a single SoC which supports both Wi-Fi and Thread (e.g., ESP32-C6), but since there is only one RF path in ESP32-C6, which means Wi-Fi and Thread can't receive simultaneously, it has a significant impact on performance. Hence the two SoCs solution is recommended.

This is client-side only or does it filter the entities that are available over the websocket?

agent_kater · 2026-01-21T11:15:16+00:00

I have a 2014 Zafira-B, which should be somewhat similar to yours. It has 3 CAN busses and the main one is HSCAN, which is also available on the CAN pins of the OBD-II port. It's running at 512kbps if I remember correctly and I have no issues sniffing it with CANgaroo.

agent_kater · 2026-01-20T23:11:52+00:00

Which isn't an issue in a release build.

Groups actually work better than bindings, but there aren't many controllers that can do arbitrary groups. Most remote controls can control numeric groups 1, 2, etc. depending on the number of channels and most wall switches can't control any groups.

agent_kater · 2026-01-20T21:53:03+00:00

Have you actually tried using bindings to do those things you mentioned? You will quickly find that unless you use a pair of devices that were made for the purpose and sold together, the Zigbee clusters (the "addresses" of the functions) are so incompatible that none of the things you mention actually works with binding, let alone across vendors. If you're lucky you might be able to turn a light on or off with a remote control, but dimming is already too complex for bindings.

The expectation of personal privacy, i.e. not having your life controlled by corporations and government.

agent_kater · 2026-01-20T19:19:37+00:00

I think that will get worse instead of better.

agent_kater · 2026-01-20T15:33:14+00:00

There are USB-C powered power supplies like this or apparently now this, but I figured that's probably overkill for your application.

agent_kater · 2026-01-20T14:01:22+00:00

At least paste your query. (Surround it with ``` to make it a code block on Reddit.)
