OK, so?

• We will ship
• 50M smoke and co detectors
• 40M to 50M appliance controls
• 10M water heater controls
• 5M thermostats
• 1 2M refrigeration controls
• ...
• We want to/need to/must interconnect these
  devices!

Goals

• Lots of Sensors 100s Many controls 10s

• large 64K
• complex
• expensive
• untested
• not IP compatible
