You can specify the brightness by using the action 'Turn on and custom lighting'. Since you want to trigger the light based on sensor input, you can adjust its brightness for different times of day by setting effective time periods in automation rules. Create as many rules as you need for each brightness/time combination.

Here’s an example setup:

Effective time: Weekdays, 7:00 AM – 12:00 PM
Trigger: Sensor is activated (choose your device and rule, e.g., T100 motion detected or T110 sensor opened)
Action: Turn on bulb in warm white at 50% brightness (*Action: Turn on and custom lighting)

If you also want the bulb to light at the same brightness when switched on manually in the app, add a second trigger to the same rule. When a rule has multiple triggers, the automation runs if any of them is activated.

Example:

Effective time: Weekdays, 7:00 AM – 12:00 PM
Triggers:
1. Sensor activated
2. Smart bulb is turned on
Action: Turn on bulb in warm white at 50% brightness
