pretty good deal. I don’t understand why they are so cheap.
I think these will occasionally stick on “Active” until someone walks thru at least 3 minutes later and it times out again. I manage it by filtering the status of 1,2, or 3 sensors to a composite Simulated Motion Sensor with Webcore, and if one sticks then I ignore it for a while.
Would you mind sharing your piston? I have couple of these lying around as I bought them to turn the lights on/off. But because of the 3 min timer, it is kind of useless for my application.
My experience with these is completely anecdotal but I purchased one of these to control a light in one of my rooms and I constantly have issues it. When I first connected mine, it worked great for a few days then it would seemingly lose connection to smartthings. When it stops working I need to pull the batteries and after a few minutes it decides to work again, for a while anyway. I stopped messing with it since the convenience of not turning on the light manually was not worth the hassle. FWIW I have about 5 of these bay boys around the house and I find them to be much more reliable with ST. http://a.co/eTijSnU
I too have issues with these dropping connection occasionally but also just but a few more because hard to resist 12 bucks. Since they are so big I have them in out of the way places so it’s also possible my zigbee network isn’t strong enough there, but I really don’t think that’s it. Last night I realized one of these had been reporting temp for about a week but no motion. Pulled batteries and came back to life just fine.
