Use my Benq projector remote

    Hello!

    Beginner here, so apologize if my question is stupid, but after doing researches, I'm just very confused about where to look.

    I want to use my Benq projector remote for Libreelec, how can I achieve this?

    My setup is:

    - Librelec 10.0.1 on RPi4.arm

    - Not a vanilla RPi: I added a Hifiberry Amp2

    - Projector BenQ TH585

    - RPi4 and projector are connected by HDMI

    What I understood so far:

    - I could use "CEC" to use the Benq remote control on Kodi. Is it suppose to work out of the box? I had a look at the settings and got scared to break things. (And the CEC adapter is already enabled)

    - I also saw somewhere that the HifiBerry Amp2 were using "GPIO" pins and that it could be an issue with remotes. I don't understand what it means and can't find where I read this (maybe here?), so maybe I'm saying non-sense, but I just wanted to gather here everything I found so far.

    - I could use Flirc2. Is it relevant for my case?

    Sorry if that's all confused, I'm just a bit lost, not being very tech-savy. Any help/clue/hint will be much appreciated :)

    Yes. You should be able to use CEC unless the Benq has a mind of its own on CEC implementation.

    I have no thoughts on the hifiberry since it's "not my department".

    Okay thank you very much!

    In that case it definitely does not work out of the box for me :D

    So if it does not seem to work, the issue can be either the projector, the cable or the raspberry? Is there some utility to troubleshoot this? Otherwise I think I'll give up, I can even find a single occurrence of "CEC" in the projector manual or data sheet, and it looks like the problem could be anywhere in the chain.

    Also, could the fact that I'm using a HDMI cable + HDMI to micro-HDMI adapter be an issue?

    What could be a factor is the HDMI port number on the Benq. The default for Kodi is '0' , and usually autodetection does its job, but you could try a different port number (1,2,3..) in that scary CEC settings page. Change the setting and restart LibreELEC.
