Zotac IR remote not working

    Hi,

    I have a Zotac ID81 remote, trying to get it to work with a Raspberry PI 5, please see this thread.

    Zotac ID81 remote with LibreElec 9.2.2 | realmtech.net

    This was fixed back in 15/04/2020.

    I have followed the instructions but it doesn't work.

    I have checked the HW and its fine.

    I assume the patch was added in as its so long ago. ?

    My feeling is that this should just we working out of the box by now, its not working and I have no Idea why its not working.

    Help would be appreciate,

    Kind Regards,

    Joe.

    Hi, if you have a bit of experience in electronics (or know somebody), you should use google to search for "RPi IR receiver". A single cheap component, 3 wire, and no more problems with the USB receiver.

    Thx for the suggestion, its a fair point.

    I was kind of hoped that having a nice USB receiver that all in a plastic housing and a remote that works it would be a doddle, seeing as it was supposed to work,

    such a shame, as its always seems to be the case. HW support under linux is always really problematic. Nothing every gets quite finished.

    I was kind of hoping that the USB would be detected and plug and play, its sees the USB device and reports it correctly it just doesn't work, and it has been working for other people.

    Even the 3 wire solution seems to come with a whole heap of SW issues to get it working its doesn't just seem like plug and play.

    "On a Raspberry Pi, LibreELEC can use the GPIO pins to communicate with a hardware IR receiver diode, as long as config.txt has been suitably modified to enable GPIO support."

    What does "suitably modified" mean ? A very long page of how to hack around and get it working.

    If I go down the 3 x wire route, it still seems like a complete can or worms as well, not plug and play.

    1) This libreELEC guide doesn't explain which pins to connect, or how to tell LibreELEC which pins to use, or what decoders are supported !

    "Note that LIRC requires compatible hardware to decode IR signals. An in-depth discussion of IR decoder hardware is outside the scope of this document."

    2) I have no neat external IR receiver and lead, if I buy a 3 wire LED.

    3) I need to select a decoder and have to wire that up.

    3) I have no remote to start playing with.

    5) Perhaps my Zotac remote will work with the 3 x wire solution ?

    6) Going to be a load of work figuring out the right protocol for my Zotac remote over the 3 -wire.

    I hoping somone has a Zotac ID81 working with LibreELEC and can please help.

    The OE patch added a driver for Spinelplus IR receivers, but it requires a bunch of USB ID's to be patched into common kernel files that are frequently updated, and because the original author never bothered to upstream the driver, the downstream patch needed constant rebasing against kernel changes. This task quickly becomes a problem chore, so the patch was eventually dropped.

    In the absence of a proper kernel driver you can fall back to using lirc, which still exists in LE but (IIRC) lircd is no longer started unless /storage/.config/lircd.conf exists. Step 2 and Step 4 from the article you linked should still be valid.

    I'm using this type of IR receiver for years and didn't had any problem. Your remote looks like it's a MCE RC6 one, that code is the default supported by LE. So for that remote to work with RPi, you need the "3 wire solution" and in the config.txt enabled the line with "dtoverlay=gpio-ir,gpio_pin=18". That's all.
