I extended my alarm clock with a Lullaby option 
Lullaby initiates with a HTTP Post command which is send from Tasker when I lay my phone on the wireless charger next to my bed. It first changes the sliders (via MQTT) to a different value and then to the value of which my alarmtime is set (readout with AutoAlarm). Then it recalculates the time left untill my next alarm, sends this as TTS to my bedroom speaker and finally fires the Lullaby trigger (if it’s set to “On” of course).
If anyone is intrerested in the configurations, let me know.
