I'm a newbie ;)
My Plan: I want to have one "Master" RPi and have this one as an "center of home automation". The other Pis are going to be in differnet rooms and will be connected to the network via Wifi. They shall have different functions (as booting pc, changing height of desk, a TV-wall if someone gets near by, and such things). Till now I heard about "MQTT (a good one for the Pi is Mosquitto)". Does that fit my needs? And if so, do you guys know about good tutorials regarding this? (broad question, I know <3 )
edit: found some mqtt tutorials with OpenHab - is that a reasonable path to go?
