Hello, I can look at adding this type of step, but I think what you're aiming for can be achieved with the existing functionality - you might just have to create two separate sequences.
First, you need to create your 10 minute window. To do this, use a variable (in this example period_started) to track whether or not it's within the 10 minute window:
- Sequence trigger - your random environmental trigger
- Set the variable period_started to true
- Pause for 10 minutes
- Set the variable period_started to false
- Triggered when the sensor detects motion
- Check if period_started = true
- If yes, perform whatever other steps you want to run
- Else - do nothing
