5 seconds delay between motion sensor and LIFX bulbs—Can I reduce this?

Hi JD, ST motion sensors and there are the 2015 model

OK, the first thing I would look at is the placement of the motion sensor. there is an FAQ for this (this is a clickable link):

Note that all of these PIR type sensors work by detecting very small changes in heat that move across the Detection field. Consequently you will get the fastest response if the motion sensor is 90° to where the person enters the room. If you have the motion sensor set so that person is walking straight on towards it, that can actually give you the slowest response time.

FAQ: Where to locate motion sensor for fastest response?

[image] I have a downstairs hallway that’s perhaps 12 feet long, with a doorway to a spiral staircase at one end (where the picture is taken from) and a door into the garage on the other end. As you can see in the picture, there’s a jog in the hallway. Not seen here are another doorway about 4 feet to the right of the one by the staircase, a bedroom door to the left at a 45-degree angle (you can just make out a bit of the trim on the corner of the wall, near the top), and a laundry room doorway on the right as you go through the jog. The hallway is dark and I want to automatically turn on the lights when I come off the stairway or enter from the garage. I have an Ecolink motion sensor and I’ve tried placing it in each of the four locations marked with circles. (The two near the top are …
