Current situation

Spacenanny

SpaceNanny is the master node (node0) in the nrf network it takes care of transmitting the received sensor data to graphite (running on graphite.nurdspace.lan) the current code runs from a screen under the user nanny in the window called NRF this is how you restart it

sudo bash
cd /home/nanny/NrfPiNode
while true ; do ./NrfPiNode ; sleep 1 ; done

The nodes

  • 1 Located near slab
    • Temperature
    • Pressure
    • Humidity
  • 2 Located near the front door (Only for relaying data from its child nodes)
    • 12 Doorbell node
      • Listen for a doorbell press
      • Temperature
  • 3 Skip button
    • Pulse contact for skipping the current track
