Hi @z_sojma,
unfortunately Aqara doesn’t have native states or variables you can reuse in automations. I solve this in a similar way to what you described — with multiple automations and clearly defined modes.
In my setup the house has three main modes: Morning/Evening, Day, and Night. For lighting this means: 100% brightness in the morning/evening, 0% during the day, and 5% at night. I use scenes to enable the right automations and disable the others. These scenes themselves are triggered by other automations — based on time, lux values from sensors, or sometimes just manually.
Yes, it takes a little setup work, but it runs very reliably and makes it much easier to adjust timing or logic in just one place. I also described it here: Different Modes for Your Smart Home – Why They’re a Game Changer
Always remember: “If your car is smarter than your home… you’re driving into the future while living in the past”
