Another option to consider is the Phillips hue motion sensor which is very fast. You can set it up one of two ways, either just connected to the hue bridge without bringing smart things into the picture, which will probably be the fastest, or using a custom device handler from the community which let you connected to the smartthings hub.
But no matter which one you pick, all of the advice on motion sensor placement will apply, so do read that FAQ first.
At my house, we use the Hue motion sensors, with the hue bridge, not with the custom code, and we get the fastest response that way, just about 400 ms (just under half a second). But for various reasons different things may work in different households.
Thank you - this was excellent. I went back and read every thing and I think I simply bought the wrong sensor. From what I’ve gathered, my sensor placement isn’t terrible but I do plan on doing some experimentation. One HUGE lesson learned: Use some blue painters tape to experiment with placement BEFORE using the double-stick tape that comes with the sensors! Since I’ve made the investment in Hue, I am going to use their sensors. Fingers crossed! Thanks very much.

Hey there and welcome the Addiction! @JDRoberts has given you some fantastic advice and I figured I’d throw in my 2 cents as well.
Everything I say is based solely off of my own personal experience… so, it may be and probably will be different for you. But, here goes…
The only thing I’ll own with the ST branding on it is the Hub. i will NOT touch any of the other devices, I’ve just seen too many reports of issues with them over the past 1.5 years.
I sweat by the IRIS motion sensors that JD mentioned above. They are almost instant for me, If the automation is running local, it is pretty much instant. if they are cloud based there may be a second delay. But still very very fast.
Sensor placement is everything! Location Location Location. I learned very quickly to not put them over a door, unless it is at the end of the hall and I want the lights to come on as I walk down the hall. In my bathrooms I have found that putting them in the corner of the room, just inside of the door, seems to work best. I have mine pointing down at an angle and pointing out from the corner. The sensors have a fan shaped sensor area and they work best if you are walking in front of from one side to the other, so where I locate mine causes persons to break that barrier as soon as they enter the room.
Also, the IRIS sensors are very well priced. Buy a lot of them! Each of my bathrooms has at least 3. One for walking into the room and keeping the lights on while the person is at the sink. One in the shower so the lights do not go out. And these things are super crazy sensitive. The closer you are to it, the more sensitive it is. People like to sit really still while they are using the squatty potty… lol… and then the lights go out! So, I put one right next to each toilet and the slightest movement keeps the lights on.
and finally, throw away that double stick tape. Go to the hardware store and get you some of the blue sticky gummy rubber stuff that you ball up and stick things to the walls with… it works great and doesn’t destroy the drywall.
I don’t bother with the double-stick tape at all - I use the Scotch Command strips and cut them down a bit if needed. That also has the advantage of allowing you to easily take down the device to change batteries and then just stick it back in place.
Thanks Bamarayne - very helpful and practical. I bought the ST sensors trying to stay w the brand but your advice to get best of breed inside the eccosystem makes sense to me. Wow, 3 sensors! I was just thinking 1. lol. Plus I didn’t realize these could be placed in a shower (i assume not in direct contact with water but steam is ok?)

In one shower I have it up in the corner. In the other it beneath a stone shelf… So the never actually get wet… Though my wife has tried to kill the one under the shelf several times by spraying it… Lol
Great advice here on the motion sensors. One other thing to think about is bulbs vs switches. Not sure if you went with bulbs for the color aspect, lack of neutrals, etc., but switches may work better for visitor, significant others, kids, etc. If you haven’t yet, ths is a good read
thank you for this!!! I am trying to add motion sensors to a baby nursery mainly to be used at night with a lamp that will have a Hue bulb, but I had not idea where to start, and I looking into the monoprice and ecolink, but then read that they are too slow. I am definitely going to try the Iris Sensor.
Does anyone know if they go on sale often? I know I can use 15 off 50 coupon if i only buy a pair, but dont we all want to maximize our discounts? LOL
Yes, I’ve seen them down around $20 sometimes but it has been awhile. Also, different Lowes stores will sell them at different prices so YMMV. They are also sold on Amazon.com. Amazon did drop the price as low as $17.17 back in late Sept 2016 but has been stuck at $30 ever since. Check the Deals category often. Still, if you have the $15 off $50 coupon, compared to other motion sensors, the price is still very reasonable.
Sometime Amazon Warehouse will sell stuff cheaper. Currently the Iris motion are only a little cheaper than new. $26.99 you sometimes have to click the other offers section on the right side to find them.
OK everyone - I wanted to report back on this. I bought 4 Hue Sensors based upon the advice of all ya’all. They are PERFECT. Near instant recognition. I am using the native Hue App for this, not the ST apps, though I plan on experimenting to see if one is better than the other. I also bought 4 Iris sensors but I have not played w them yet. So far I am using the Hue sensors for entry and the old (ha ha, 1 week old) junkie ST Sensors for motion IN the room, though they don’t seem to work 100% of the time like I expect. I’ll likely use Hue for entry into rooms and Iris for motion IN the room. Thanks so much everyone.
