Hello,
I have the same problem with my CI540 and Harmony remote, but it is random, and I noticed the same behaviour with Openelec 7.0 beta 3 :
- Powering on the CI540, using an harmony hub with "Zotac CI540 multimedia device" IR profile, always works.
- "Sometimes", once Kodi is started, IR signals are ignored
Openelec 6.03 worked fine, and I experienced the issue since Openelec 7, so this seems Kodi-related.
