Bumping this thread because I got two of these (well, the Monoprice version) a few weeks ago and they're not working right with my Vera Plus on the latest (October 2017) firmware. They pair just fine--even choosing Generic Z-Wave Device (but I have also tried choosing the Vision Device--the only change was the setup instructions). They exchange security keys and then the three child sensors (Temp, Humidity and Light) show up. I give them all names, assign them to a room and wait. Within 10-20 minutes, I see values for all those sensors show up in the UI and it looks like all is well.
Then, a few hours later Vera gives me "Can't Detect Device" for the motion sensor. It looks like values for temp, humidity and light continue to update periodically, however.
I then go through the exclusion process (successful), reboot Vera for good measure, and re-pair the device, leaving it right next to the Vera for hours, only to get the same result.
I am somewhat ignorant of the realities of battery-powered Z-wave devices like this. Is this because the device doesn't support polling and Vera is trying to poll it? When I look at the settings screen for the motion device, wakeup interval is 1800 and the polling field is blank (meaning default, but I have no idea what the default for this device is).
Should I set polling to 0? Should I change the wakeup interval? Can anyone who has these sensors working properly tell me what values they are using there? I don't know if I'm barking up the wrong tree with this or if the sensors are just defective (odd that two would have the exact same problem though).
Thanks for any ideas.
