Hey, since I got the newest build from libreelec I can't wake up my Raspberry PI 3 with CEC, after I shut down my TV. I had no issues with 008 build. The systems keeps working and I can wake up the screen by moving my mouse. After that the CEC remote works fine and faster than before. I got a Philips 32PFL5605H TV
If you need more information. Let me know.
