 Home automation/control system consists of multiple parts:
 - nodes
+  - decentralized, nodes just broadcast measured data over a two-wire
+    communication network (clock/data), addresses are auto-assigned, no prior 
+    setup necessary, no central bottleneck or single point of failure
+  - node types
+    - environmental measuring (temperature, humidty, CO2 and others)
+    - motion detection, door/window sensors

   - small PCBs based on AVR microcontrollers

     - AtTiny85
     - AtTiny841
     - AtMega644
   - modular operating system written in AVR assembler

     - one-wire bus
     - two-wire-bus
