Sleep as Android
It’s just a really great alarm clock app, but with tons of other sleep tracking functionality. I’ve always had trouble sleeping through my alarms, but I never do with this.
If you run Home Assistant, Sleep as Android can publish events to an MQTT broker so you can create automations based on those events, like “smart_period”, “awake”, “not_awake”, “alarm_alert_smart”, etc.
I used tasker to slowly ramp up my bedroom lights before my alarm goes off. Makes it easier to get up and not as jaring.
As a backup option, you can give Google Assistant or a Google Home the following commands: “at 10PM, sleep {lightname}” to dim, or “at 6AM, wake {lightname}” to brighten - both work over the space of a half-hour, and for some odd reason that’s not customizable.
