ToDo

• send confirmation signal back to level monitor box, use to trigger sleep
• sleep mode
  • see avr sleep example: https://github.com/dorkmo/ArduinoSMSTankAlarm/blob/master/TankAlarm072017.ino
  • see digi sleep mode: https://www.digi.com/resources/documentation/Digidocs/90001456-13/reference/r_wk_sleep_mode.htm
• syncronize sleep/wake times
  • wake up every 30 minutes, broadcast till other box wakes up, do the business, then sleep for 30 minutes

Questions

• can an arduino digital pin put out enough amps to power the relay module?
  • could power down relay module when not in use

Sleep Routine

• when transmition of kill or stay alive broadcast is complete and confirmed.
  • send "Z" to say ready for bed. When recieve "z" back, end all transmissions.
  • xbee sleep mode will engage after 2 minutes as predefined time in XCTU settings
  • arduino will go into avr sleep mode for 8 seconds at a time, keeping count.
  • after 28 minutes wakeup xbee as defined in XCTU sleep timer
  • after 30 minutes, end arduino avr sleep.
  • Broadcast "W" awake status every 1 minute using delay(). wait for "w" confirmation.
  • Broadcast status of liquid level switch. "K" to kill. "A" to stay alive.
  • Wait for Confirmation of "k", "a", or "E" for error.
  • Broadcast "Z"
