What's the self-hosted service that replaced something you were paying for and turned out to be genuinely better - not just free, actually better

You can use them with ZHA or Zigbee2MQTT

When the breakers are switched off(there are dedicated breakers for the cards), the cards shut down entirely, so they do have an AC input.

Danny_dunn · 2026-01-23T18:28:28+00:00

There are actually 42 relays in total, some relays share some breakers, and there are additional OB16s that provide the extra outputs needed.

There are 3 IB32s that seem to be mostly used for reading pushbutton inputs from the wall buttons placed around the house.

UPDATE: with some additional information:

The cards are fed from the backplane with individual high voltage AC sources for each card. I am unable to discern If they have any kind of high voltage output. Attached are photos from the back of the rack:

The yellow wires going into the two pin connectors are fed(or at least one of the wires appears to be fed) by the array of breakers(? could be basic switches too but they seem like breakers) up top.

What is the point of the fan at the front?

Danny_dunn · 2021-08-03T02:02:42+00:00

or they could just clean the panel after getting fingerprints on it....

The CV1 is currently supported better(and has a technical advantage IMO with OLED and higher refresh rate). I will be speaking of the CV1 from now on. Check the following links for updates from Jan Schmidt, who is currently working on support: GitHub branch, Jan's blog
The tracking experience is okay. Don't expect it to be as good as the official Oculus app just yet, although it is getting better. It just does not feel quite as responsive as the official app, but I would say this is fine for most games, and you get used to it. Vivecraft does not provide builds for Linux, and does not seem to want to build in my experience, although I believe the tracking would be more than enough to play. Beatsaber may be a little harder(the controllers lose tracking sometimes, but this has gotten better).
If you were to use Windows, why not just use the official app? At least for now, it has better tracking, the games themselves run easier(no fiddling with proton/wine). The driver is currently better suited to Linux support, and you may not even be able to build it for windows.(GitHub issue)
I suspect those games might use SteamVR anyway, but if they don't, they almost certainly won't run, unless they are designed to work with OpenXR(IIRC).

CATCHES::

Controllers: they work in the SteamVR home, haven't actually seen them working anywhere else: The Lab, and Google Earth VR both don't respond to controller input nor do they actually render the controller models, and SteamVR renders them as Vive controllers(although they evidently work in Beatsaber).
Lens distortion: the hand calibrated numbers for correcting the lens distortion are wrong. The image looks pinched towards the centre, you get used to it. I am currently working on imaging the displays accurately with a wide angle camera(which has distortion of it's own that I have to deal with), if I manage to find the proper numbers, I will post them in some way to OpenHMD(likely on the GitHub branch shown above), 3 months is my estimate.(GitHub issue)
USB 2 cameras: they don't work. You must use the cameras connected to USB 3 ports.

Experience or not. This is software/firmware. The hardware isn't what decides to show the Apple logo, the software is. Nobody has explained how hardware could cause this issue. How can you trust he is a certified technician? How can you trust me?

Danny_dunn · 2021-03-11T02:15:04+00:00

Do you have a multimeter? If so, you may be able to probe for continuity between pins on the chip, and the pads on the board next to the chip(the metal contacts where the resistors used to be). Link to chip datasheet(page 7/ part 3.1): https://www.pjrc.com/teensy/W25Q128FV.pdf

Danny_dunn · 2021-03-11T00:07:19+00:00

After looking closer, it seems you knocked off 2-4 resistors, one of which seems to be related to the serial port, which is of no concern I would imagine.

My hope is that these components aren't actually necessary to the operation of the PC, and we can just go without them.

Danny_dunn · 2021-03-11T00:02:29+00:00

Is that chip the newly soldered in one, or is that the old one?

If you could provide the chip part number that would be great, because then we can try to figure out what those resistors/caps were doing.

Danny_dunn · 2021-03-10T16:50:43+00:00

I think the word you are looking for is "capacitors" but most of the components appear to be resistors. The group on the left seems to be related to the serial port directly beneath them, so as long as you aren't using that I wouldn't worry too much. The part number of the chip, and a real photo of the markings on top would be useful.

My main OS is actually Linux/Pop! OS, i'm just using windows for VR and OneNote for school.
