David, would you recommend the iris motion sensor over the ST motion sensor as well? I currently have one running in the bedroom to turn the lights on when you walk in the room… Has worked good so far, however I do notice you’ve taken a good 3-5 steps into the room before the lights trigger.
The iris sensor is typically one of the quickest to respond, so I would look into two possibilities.
First, the placement of the sensor itself. See the following FAQ:

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 …
Second, if sensor placement doesn’t solve it, then consider the “strength of your mesh,” which means how many mains powered devices you have and their placement to help pass the signal along to your hub. Battery powered devices cannot help in this regard.
See the following thread. Start with post 11, then go back up to the top of that thread and read the whole thing. (This is a clickable link)
One more thought. While I understand the marketing reasons for the decision, the fact that SmartThings gives customers zero guidance on how to set up a network backbone does lead to a lot of frustration that shouldn’t have to exist. if people knew that
.1) The hub should be located centrally in the home, both vertically and horizontally. Don’t put it in a garage or basement as those have concrete and pipes and metal objects which will reduce signal. If your Internet router is off in some inaccessible corner, you can use a Wi-Fi access point that has a ethernet port on the side and plug into that. Also, the hub should not be put in a cabinet. You just want to make it as easy as possible for signal to spread around your house.
.2) you need one device that can repeat about every 40 feet…
