Hi @kiptanoi ,
FYI: I have deprecated this blueprint in favor of this one: Adjustable Wake-up to Android alarm
I do have a script blueprint to increase or decrease the brightness of a light that doesn’t support transitions: Increase or decrease light brightness over time - Blueprints Exchange - Home Assistant Community (home-assistant.io)
Maybe you give the “new” wake-up blueprint in combination with the increase or decrease script blueprint a try. That’s what I have been using for years now.
