Please implement two attributes in Sonos Integration (Sonos - Home Assistant) showing if Sonos Alarm or Sleep_Timer is currently running.
In old FHEM Sonos Integration this was available and I used it to slowly increase / decrease Volume when Alarm or SleepTimer was running and the HUE Bulb as wakeup Light in combination with the Sonos alarm clock.
I guess this would not be too difficult to implement and very helpful.
