[Z-Wave Review] ZOOZ Z-Wave Plus 4-in-1 Sensor (ZSE40)

I'm going to try something new. Home automation has become a large interest of mine lately, which is something I haven't really been involved in for a few years now. The industry has changed a lot, and I want to share my thoughts on Z-Wave modules, and other devices that I have bought and added to my Home Assistant install. If you want to follow along, go buy a SBC (Raspberry Pi, Pine A64, oDroid XU4, or similar), an Aeon Labs Z-Stick Gen 5, install DietPi, and install Home Assistant us ing my recent installation guide.

This is a new format for me, and if you think I could display information in a more efficient manner, than please contact me and tell me how!

Anyway, let's get into this first product review.

ZOOZ 4-in-1 Sensor (model ZSE40)

What is it?

The Zooz 4-in-1 Sensor ZSE40 is a multisensor that can monitor for, you guessed it, 4 different values.
Temperature, humidity, luminance (light level), and motion.

This device contains a Z-Wave Plus chip, which provides AES signal encryption if used with secure inclusion. It claims a 100 foot (line of sight) range for the motion detector, and does include a tamper protection sensor. Includes a 1-year warranty.

Why would I want this?

Now I'm no Z-Wave or Home Automation expert, but I like to think I know what's going on here. In my experience, there are two different types of Z-Wave modules. Those that collect data, and those that do things. This ZOOZ ZSE40 multisensor is obviously the former, in that it collects 4 different data points.

The first reason you may want this is simply because you like to collect data and analyze trends. Put one in your kitchen and monitor the temperature and humidity during different activities (cooking, cleaning, etc). The best reason you would want one is that you can have your automation system (Home Assistant for me, maybe Samsung SmartThings or a Vera for you) react based on certain conditions. Maybe you want your Z-Wave light switch to turn on the lights if the Luminance level is below 30% and motion is detected. This multisensor would be exactly what you'd need to achieve that.

Does it work?

For me personally, it worked as expected. Once included to my Z-Wave network, it immediately started reporting the temperature, humidity, light level, and motion without any configuration. However, I did use Open Z-Wave Control Panel to make some configuration changes, such as changing from reporting in Celsius to Fahrenheit as well as changing the status LED to off (instead of blinking certain colors based on activity) and changing the motion sensitivity.

It took me all of 10 minutes to setup and be available to Home Assistant.

What's in the box?

First of all, the packaging is pretty nice. Contents were packaged neatly into a little red box with a top opening, and that red box was slid inside of a black cardboard sleeve that has all the product branding.

Inside the red box contained the sensor itself, mounting bracket with 3 screws, and 2 AAA Energizer battiers.

The directions are very clear in that you should include the multisensor to your Z-Wave network prior to mounting, which I did. Once the inclusion was complete, I went ahead and mounted this in my kitchen. My kitchen is rectangular in shape, with an exterior door and interior doorway both on one end. So I decided to mount the sensor on the middle of the opposite wall, and the sensor did well to cover the entire room.


Was the inclusion easy?

Yup, very easy. I stopped my Home Assistant service, started up Open Z-Wave Control Panel, and set my Aeon Labs Z-Stick into inclusion mode. From there, I did as the instructions said and pressed the button on the device twice quickly, using a paper clip. It immediately showed up, as expected. One important thing of note is that the device was included, and went into sleep mode (as it normally will), which means Open Z-Wave didn't have a chance to pull current values and configuration items. It's an easy fix by just pressing the button on the multisensor three times quickly, which will wake it up and make it talk to the Z-Wave network.

After doing this, I immediately saw the current values in in my Open Z-Wave Control Panel.

Likewise, here are the available configuration options, before I changed anything.


To further explain on these options, the instructions did include some helpful information.

  • Parameter 1: Temperature Unit which allows you to choose from Celsius (value 0x00) and Fahrenheit (value 0x01)
  • Parameter 2: Temperature Reporting Threshold which is the number of degrees changed required before a change is reported (vale from x to x)
  • Parameter 3: Humidty Reporting Threshold is the percent of change of humidity required before a change is reported (value from 1 to 50)
  • Parameter 4: Luminance Reporting Threshold is the percent of change of luminance required before a change is reported (value from 1 to 50)
  • Parameter 5: Motion Sensor Re-trigger Duration is the time, in minutes, before a motion event is re-triggered (value from 1 to 255)
  • Parameter 6: Motion Sensor Sensitivity Adjustment is the level of sensitivity of the motion sensor (value from 1 to 7; 1 is very high and 7 is very low)
  • Parameter 7: LED Mode is the functionality of the LED (vale from 1 to 3; 1 is off, 2 is temperature indicated with pulsing light and motion indicated with flasing light, 3 is temperature and motion indicated with a flashing light)

My thoughts

Overall, I'm happy with the device. It does everything it say it will do, and works flawlessly with the Aeon Labs Z-Stick and and values show as expected in Home Assistant. Here is a screenshot from my phone showing the current status of my Kitchen group, which currently has this multisensor, a Yale Real Living deadbolt, and an Everspring door/window sensor.

The only negatives I may have is that I think the temperature reading may be reporting a little higher than expected. I have a separate thermometer in there to compare to, which has been about 1.5 degrees cooler. The multisensor is up near the top of the room, so it's possible that it's just warmer up there. Also, the mounting hardware seemed overly complicated, but still easy to work with. I suppose it's meant to be used in the corner of the wall and ceiling, and not in a vertical corner, but I could be wrong. It took me about 5 minutes to figure out the best way to mount it.

That aside, this sensor does everything I expect, at a price that's cheaper than a lot of the competition (Aeotec, I'm looking at you).

My Recommendation

If you're in the market for a Z-Wave MultiSensor specifically for temperature, humidity, luminance, and motion detection, I say buy this one over the others. I paid about $30 for it, compared ot $50 for similar offerings (worth noting that the Aeotec MultiSensor 6 also monitors for vibration and UV levels; which I have little to no use for). If you're in the market for one, I recommend buying from The Smartest House, who have great support for products they sell.

Thanks for stopping by!
