h1. 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 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
'keepAwake';
