Getting dirty hands isn't a problem, I'm already trying to install domoticz from ArchLinux (runeaudio image) without the image and it works well.

Only problem is domoticz run but runeaudio don't... But that's another story..

So I think I'll go for XU4..

Thanks for your reply.

thank you for sharing your project! I installed and till now everything is working fine on both raspberry pi 2 and odroid XU! Sorry for the late question, but can you tell me if you got an Odroid XU4 ? I'm wondering if I'm going to choose it instead of RPi2 for power reason as I want to use one ...
