Have any of you used these "15902 Monoprice Z-Wave Plus PIR Multi Sensor, Temperature - Humidity - Light… I bought 2 on sale and I can’t keep them online. Daily, one unit is online and the other isn’t and vice versa. They seem to work OK when they stay online. Does anybody know if there is anything I can do for this? I am using the new app.
Have you tried a Z-Wave repair?
you may need to add a z-wave repeater between your hub and those devices
Yes, rontalley I have performed a Z-wave repair. One of these is about 10ft from the hub and the other is about 20ft. I see no need for a repeater. I think they are just junk.
I had trouble like you describe with a door sensor (and the replacement). I never could get them to work beyond the initial pairing. I was trying to mount it (after I thought I had it figured out) and dropped it on a concrete floor. It never came to life after that. I gave up on the sensor and brand.
