Never mind, I found it out myself by browsing through MySensor.cpp, apparently nodes are sending in their parentId during startup.

Multi messages like 0;3;0;9;1;foo\n0;3;0;9;2;bar\n0;3;0;9;3;foo\n0;3;0;9;2;bar\n must be understand also. I got it from the tcp stream of the actual ether-gw.

@pit007 said: -> Where can I get the info for the unit (°C or F) from the GW/Controler sight? It is the controller that sends out unit configuration to the node. Not the opposite. The unit magnitude has to be agreed in advance by controller/node. The protocol doesn't currently support this to configured or interchanged on-the-fly.

@pit007 This is pretty cool, thanks for sharing.
