Looks like I just saved about $40. Thanks.
I have 1 about 5 feet from my nest. It is roughly 3 feet lower than the nest. It reads 67 and the nest reads 68.
It varies by device. I have 3 that are right on, and 1 that is either on Earth, Mercury or Saturn depending on the day. It will be fine one day and then -800* the next, then +700* the next.

Thanks for the post I just snagged 3 of them. I check lowes daily waiting for a sale I canāt see paying 30 dollars a pop for these things. I already have several of these with no problem with battery drain. Battery has been 77% since I got them as soon as they hit the shelf. I think smartthings and the iris sensor donāt report battery life correct. Just guessingā¦
Hereās what mine looks like, just got this setup a few days ago. It holds VERY steady and stays dead on with the other two I use. I think @RLDreams may have a very defective sensor! 
Iām blaming it in the fact the one that varies by 1500 degrees is also the one furthest from the hub .I had it working good for a while when I rebuilt the mesh without the Osram bulbs, then added the bulbs back in after. With all the updates of late I can assume Osrams are back in the middle messing up things after them.

Very tempting to buy more of these. I have some and like them a lot. However the led light is annoying.
Thatās one of the things I actually like about them. If I see the green light, I know it is the bulb that dropped, if no green light I know itās the PIR.

I can see that. However Iām not having dropped device issues. For me the led takes away some of the āmagicā and guests seem to be creeped out by it and think it took their picture.

Maybe you can crack them open and cut one of the LED Leeds. Poof no more light.

I see that,. Daughterās extended guest insists all the sensors around the house are spying on her. I actually wound up downgrading the lights in her room to dumb bulbs/switches. She still insists on using the wall switch in kitchen,bathroom and stairway. Which of course totally messes with the world. Now that it is getting into heating season I can not get her to understand the reason it is cold in the house is because house doesnāt know sheās home if it canāt see her moving around.

This can be connected as an ecobee sensor?
White duct tape or those expensive light blocking stickers can take care of the green lights.
Not directly, but you can set up virtual thermostats using any/all temp sensors and use ST to control Ecobee instead of letting it run itself.

Iāve mentioned this a couple of times before, but I really like this particular brand. These are stickers in white, silver, black, or black out. No residue. Various sizes and shapes. They just work really well.
If you just want to dim the light, the white and the silver will block about half of the LED. If you want total blackout, use the black out and then you can stick a white or silver over-the-top if you want that color.
As long as the LED isnāt also in the sensor slot, it should be fine. Iām not sure on the iris, though, if blocking the LED also blocks the sensor lens.
Anybody have experience with these or the ST sensors outside? I know they are not waterproof, but I was thinking of using them under the eaves to augment my Arlo camera motion detection. They wouldnāt get wet, but I wonder how the cold weather would affect them and their battery life.
I have one in my garage, battery life suffers substantially when temps go below 30 or so. They recover a bit in warmer weather but expect maybe 6 months to a year if itās not too cold. I didnāt have mine drop out at all last winter, but it did report 50% or something regularly, vs the usual 80% it was at when warm during the warmer days.

Where I am it can get to zero or below on occasion. I guess Iāll find out this winterā¦
I noticed no difference between 20 or -10, I think the battery hits a point where itās at itās lowest possible draw amperage, and cold no longer matters. It still worked, so as long as itās a new or strong battery, probably wonāt be an issue.
I find these sensors work amazingly well but only indoors for myself. I tried putting them out doors in many places with nothing in front of them that moves and found that they were reacting regularly nonstop. I havenāt had time to find a way to reduce their sensitivity so for now Iām expecting to get other sensors known for being less sensitive for my outdoor purposes. I suggest you try with just one first before buying.
