I have a Raspberry Pi B+ set up with OpenElec which I happily use as a media player for movies. What would be the best way to switch it on and off in a similar way I switch my TV or BluRay Player on and off ? I do not want to just leave it on all the time, because I do not use it daily. I can shut it down from the menu and unplug, but that is not really convenient.
The Raspberry Pi (even the B+ model) cannot be switched on/off easily. The easy way is to plug/unplug the RPi, as you already do.
To switch it on/off with a remote, you will have to plug some third-party component in the GPIO. You can either make it yourself if you are into electronics, or buy one of those RemotePi Board (I just found it, maybe other similar products exist).
The other way is to power the RPi with the USB port of your TV. When you switch it off, the RPi won't be powered anymore. But, by switching the Pi off brutally, it could corrupt your data...
