Monoprice needs to update the directions!! I RMA'd 2 of these because I couldn't get them to work, turns out there's 2 buttons! one inside the battery compartment, and another paper clip hole on the bottom! the paper clip hole controls the inclusion and whatnot, the battery compartment button is only for tamper detection apparently. this is NOT called out in the instructions.

Like the other reviewer mentions, The zwave button in the tiny circle on the bottom of the senor. Use a paperclip and it will pair right away. The manual for the ZOOZ ZSE40 has a photo if you need more help.

As others have noted, the instructions are not clear on how to include this sensor. For Vera, select generic z-wave device and have a small pin handy. There is a tiny hole on the outside of the sensor. Carefully insert the pin until you feel the end of a small microswitch. It is easy miss the switch but you will know when you feel the switch click with slight pressure applied. The sensor will flash. Be sure to be within a few feet of the controller or you will get strange errors. Otherwise the sensor has performed as expected once it was successfully included. Great price compared to the competition.

For the price, the feature list is outstanding. Where else can you buy a 4-in-1 Z-Wave multi sensor for under $50? It is compatible with the ZooZ device type in SmartThings, too, so it can work out of the box. I say "can work" on purpose because it doesn't necessarily work out of the box, and the setup instructions aren't blindingly obvious.

I bought two. It took a while to figure out that the button to put the sensor in pairing mode is actually on the bottom of the device and needs to be pressed with a straightened paperclip. It's *not* the "Z2" switch inside the device next to the batteries. That would be much too convenient! The switch inside the device is merely a tamper detection switch as far as I can tell.

Setup with SmartThings is easy enough. Put the device in pairing mode by quickly depressing the button on the bottom of the device by using a paperclip, and SmartThings will pick it up a few seconds later. That's where the easy stuff ends.

One of my sensors worked great and keeps on working great. It has been running with SmartThings for a couple weeks now without issue. The other one paired fine and sent it's initial data to SmartThings, but stopped responding after the initial sensor reading. I had to reset it 4 times before I could get it to work reliably and continue reporting status updates to the hub. I'm still not entirely convinced that it is working correctly.

So. The price is good. The setup is a bit confusing. And it might take some fussing with the sensor to ensure a trouble-free connection. All in all, it's just okay.

The Aeon multi sensor, while expensive, is considerably better. If cost is your main concern, buy this (or the apparently identical ZooZ multi sensor). If reliability and ease of use is your primary concern, look elsewhere (Fibaro and Aeon are good alternatives).

Works well with smartthings after installing the custom device handler. Good battery life (90% remaining after 3-4 weeks of use).

Does not work with wink 1 or 2. Only compatible with devices that support multi sensors.

Works good if your device supports it.

I had this sensor for several months and its working great in a protected outdoor location. I've successfully changed the temp readings to Fahrenheit via the configuration parameters but can't get the motion sensor retrigger time below 3 minutes. I've set it to 1 and can read it back and see it's set to 1 but the retrigger time is still 3 minutes.

Pretty decent, added to my veraplus by inserting pin into hole on bottom of the unit felt around for the button to depress, set vera to inclusion, searched for model ZP3111-5 in the vera search box, it even gives you a diagram of device and I left it right next to vera for about 2-3 mins until battery indication and everything popped up in interface

Works well on Smartthings with a Zooz 4-in-1 device handler. Includes Instructions are not good at all. Google the Zooz instructions and use those. Responds to motion quicker than a GoControl Motion but slow met than the Iris Motion.

Instruction that are included are not sufficient. I had difficulty pairing it with my Samsung SmarThings hub. The trick for me was to use the reset button on the bottom of the unit instead of the program button inside.
Once it was paired, it has been working as expected. I use it to monitor temperature, trigger Smart Home Monitoring and to trigger lights to go on when entering a dark home.
