I have a raspbmc connected via HDMI to a CEC enabled smart TV. power is also coming from the TV via USB - everything more than fine, I really like it.
BUT: When I turn off the system (via Pis poweroff) the TV is also shut down - thats ok for me. But if I leave the setting as it is, after some time, my TV gets started, showing the xbmc portal - the same as I would have powered it on myself.
I know that TV sets can be started via HDMI, but that would mean my pi starts somehow. Is there any kind of cronjob starting the pi after some hours? I guess the USB port of my TV is constantly on, otherwise the pi couldn't do something on hdmi port.
I don't like it to get my TV turned on during the night, no idea how to avoid it,... you?
thx in advance
