I actually described it incorrectly. I was indeed talking about the response time after using a light switch to turn on the lights the dumb, old-fashioned way.

So, yeah, you’re right, it must be the time it takes for the firmware to boot up. My question still stands, then – can this boot-up time be reduced or avoided?

Probably not. The way these lights are supposed to be operated is indeed always on. If you want to keep the old-school switch, you can put a smart relay behind it.
