If you’re just getting started with home security or home automation, then you may have already decided on Z-wave for maximum compatibility. Chances are, you plan to add Z-wave motion sensors to your system to provide backup detection in case a burglar bypassing your entry sensors by just breaking glass or to automate lighting.
There’s one catch; motion sensors can be prone to false alarms if they aren’t installed and adjusted correctly. And, the firmware in each is different so they may not behave the same way when it comes to how quickly they reset and can be triggered again. So, it’s important to know that not all sensors will give you the same performance.
Aside from the obvious features such as additional sensors bundled together, you may see differences in:
- Sensitivity and ease of adjustment
- Turn on delay
- Turn off delay (can be a few seconds to minutes)
So how do you narrow down the best Z-wave motion sensors of 2019? I’ll use my engineering degree to walk you through it.
Why is Getting the Right Motion Sensor So Important?
You can probably guess why you would care, but if not, consider the following examples. If you are using a sensor in your home to trigger lights, then you may want a very quick reset to turn the lights off when you leave a room if your hub or motion sensor doesn’t support a configurable delay.
But if you’re installing it outside, you don’t want multiple notifications for each event when the UPS guy shows up at the front door.
- It’s annoying.
- It drains the battery on the device.
- For the outside case, you’ll likely want a sensor with adjustable sensitivity so that you can avoid false alarms for animals and weather changes.
So, how do you find the best Z-wave motion sensor?
To make your search easier, we’ve put together a summary of each available sensor and consolidated the customer reviews that we could find for each. That way, you can quickly see if a particular motion sensor works for your application.

How to Use the Data
Picking the right added sensors is pretty straightforward. Just use the drop down menus to pick “Yes” for the sensor you would like to have.
For outdoor use, you may be OK using in indoor sensor as long as your temperature extremes aren’t too bad where you live and the sensor won’t get any rain on it. But, of course, the manufacturer isn’t going to warranty the equipment if it fails prematurely. The motion sensors that are labeled for outdoor use or that had multiple user endorsements were labeled that way. Just be sure to check the manufacturer’s web site if the warranty issue is important to you.
Sensitivity adjustment of motion sensors is more critical in applications with pets or outdoors. For your pets, it can help you find the right balance between ignoring Whiskers and reliably detecting people. Outdoors, the motion sensor sensitivity adjustments are helpful to dial down the sensitivity to distant objects blowing with the wind and changing cloud cover. That being said, I have seen people rave about the SmartThings sensor’s performance even though it has no sensitivity adjustment.
