Turning on TV by HDMI-CEC

Hi, I’m trying to turn on tv by a connected to rpi hdmi, but when running echo “scan” | cec-client -s -d 1 it gives me “assertion failure:./interface/vmcs_host/…/vc_vchi_dispmanx init():success == 0” any way to fix that?

Please read Using cec-client to Control HDMI Devices | End Point Dev.

BTW, this forum is about openHAB … If the problem persists please open an issue on Issues · Pulse-Eight/libcec · GitHub.

Well, fixed it, just delete gpu mem=16 from boot.txt
