Behaviour¶

• Mainswitch only listens to ambient light changes, Media-Switch keepAwake-Events
  • This makes sense. If the light automatically fades out, someone can switch it on again and does not need to care about mainswitch.
  • Multiple mainswitches are no problem
  • CANSwitch timeout has to be shorter than MainSwitch, otherwise you get hard-off, meaning an short illumination flash
  • timeouts gets reset at 1/2 of the configured time, except target value is "0"
  • CANSwitch default timeout: 4h. When you enable light at 18:00, timout is at 22:00. Waking it up on 22:00 extends to 0:00.
  • fading must be done before other switches are switched off, or TV gets shut off before user can reset via light
  • CANSwitch must send the value "0" target ambient light, so CANDis shows right value. But only when fading down finished.
  • When watching TV at day, it will switch off after 4 hours without warning. It can be switched on again.
  • Warning can be shown on CANDis; Quite silent beep. "Keep awake" "OK"
  • CANSwitch has to remember amibent light value on timeout fade-out. When an wakeup occurs, the previously set ambient light can be restored.
  • Devices need areals in EEPROM. Bus could be routed in complete house. Kitchen already has different context.
  • Regional events. 'wannaSleep', 'keepAwake', 'overTemperature', 'underTemperature';
  • CANSwitch sends 'keepAwake' when media is switched on or light is set to value > 0
  • CANDis does usually not send regionalEvents, only in the Sleep-warning

Problems / Open points¶

• Regional events look super specific. Shoould this better be an object?
• Can existing events be used for this
