Zooz 800 Series Z-Wave Long Range Temperature | Humidity XS Sensor ZSE44 800LR. Hub Required (Sold Separately). Compatible with Z-Box, SmartThings, Hubitat, and Home Assistant (Z-Wave JS).

I bought this as an outdoor thermometer to trigger my outdoor z-wave switches for my heat tape (to prevent ice dams in winter). It’s one of the only temperature sensors I could find with an operating temp range down to near zero degrees Fahrenheit, which our outdoor temps temps can reach here in winter. It came up easily on the SmartThings “add-device”, but came up as a generic multi-sensor first. But Zooz gives you easy instructions to add and select a different “driver” for the device, which then has it only showing temperature, humidity, and battery. I did notice the battery, which read 100% at room temperature, read only 75% at freezer temp. I did not change any of the default parameters like how often the device wakes up to report, which the instructions state would lower the battery life. But for my application, it reports sufficiently fast. It appears that every time the temperature changes a certain number of degrees, it reports independently of the auto-wake function. So it’s not instantaneous, but the outdoor temperature does not change instantaneous. I put it in my freezer to test, and it took several minutes both for the device to cool to freezer temp, and to report the correct degrees. It reported multiple temps on the way down to 7.1 degrees. Likewise, when I took it back out to room temperature, it took several minutes. The readings were very accurate to other thermometers in the room. Overall, I’m extremely happy with its small size, ease of inclusion in SmartThings, and accuracy. We will see about battery life. It’s supposed to be placed outdoors under an eave, and not in direct sunlight or exposed to frequent water.

I have Zigbee temperature/humidity sensors throughout the house; the one in the garage shop kept disconnecting from a SmartThings hub - even with a Zigbee repeater. I already have Z-Wave repeaters for Ring security so I got this sensor, works great. From SmartThings, I can see temperature and humidity from this (and other) sensors. Alexa shows temperature from this sensor, but won't show the humidity from any sensor. So I need SmartThings even if I don't use Z-wave. I'll need more time to assess battery life. So far, this sensor is working great.

No matter the pairing method, the SmartThings hub would not view this device as anything other than a Generic Z-wave controller. Regardless of the pairing method; I tried pairing by Brand, Device, QR code, PIN and had the hub scan for nearby devices, it always showed up as a Generic Z-wave device. The paired device would not display the temperature or humidity, but would instead present an on/off switch and dimmer control. I tried multiple times, using different methods, without success. Obviously this made the device totally unsuitable as a temperature sensor. An Aotec temperature sensor I bought at the same time as this Zooz device paired easily and correctly. If this device is not SmartThings compatible it should not advertise that it is.

I use Home Assistant and wanted to keep track of daughters room temperature as hers seems to be the coolest in the house. Installed this and at first it by default will only report the temperature every 240 minutes. Now that's a horrible default, and It felt useless! You can edit the configuration. It now reports every few min, and works like a champ!!! Absolutely love it! Having it report that often im sure will have a toll on the battery, but its super easy to replace and well Its still at 100 %!

Zooz makes high quality products that integrate well with my Hubitat Z-Wave C8 Pro hub. The drivers available on the Hubitat make it easy to calibrate the sensor and it provides reliable readings. Placement is critical. We moved a large outdoor plant in an urn underneath the sensor and now the humidity is elevated! Will be relocating the sensor as a result.

Great quality. Solid connectivity (800 LR!). Super easy to connect, great battery life, and a good value. I've bought several and I'll keep buying Zooz stuff. (Hubitat HE system)

First the good, the sensor was good and accurate. Integrates with Home Assitant using ZWave Stick. Now the bad, First sensor did not work and would not pair with Zwave Stick at all. Got a replacement but still couldn't get it to pair with zwave stick. It finally paired after almost 50 attempts to pair and 20 resets. The default refresh interval is 12 hours which is too slow to track temperature for Smart Home. I adjusted the interval to update every hour, but it may have decreased the battery life. After about 3 months of use, stopped working completely. I have replaced battery but the sensor still doesnt work. It can no longer reset or be forced to wake up as well. I do not recommend this sensor.

I had a lot of trouble getting this up and running on my Home Assistant Z-Wave network. At first it would only read 32 degrees F in a room that was 74 F. I tried many different things to fix this and eventually had to do a firmware update to get it working. Getting the firmware update to go was also an issue, because this device is set up to only check in on the network every 4 hours. So if the temperature is not changing, it will not send or receive any data on the Z-Wave connection. Since the temp was stuck and not updating, it was going to take forever to get this thing updated. I eventually figured out I could force it to wake up by taking the cover off and hitting the tiny button four times. I had to do this every time I wanted to update something or change configuration and not wait for it to wake up again. After I get the firmware update done it was reading CLOSE to correct, but still about 2 degrees off. There is a calibration function, but again, you have to do a configuration change. And if you don't want to wait for the wake up interval, you have to pop the cover off and push the button again. All of the configuration options are in strange units and most are not explained in the manual. This unit also has a limited temperature range of 40F to 104F, despite having an advertised range of -40F to 257F. Overall I feel like this unit is very overpriced for what it is. I have found equally capable units for 1/3 this price. Also note, it uses an unusual battery, the CR2450, that is not as easy to find as the ones used by other devices like this.

J'ai installé ce capteur dans mon jardin, dans un boîtier électrique ouvert pour le mettre à l'abri des intempéries, sous un kumquat et il fonctionne parfaitement. Il se situe à 20 m environ du récepteur Eedomus.

Do not purchase. This sensor is software locked to only read between 0C - 32C. Useless in anything but a conditioned indoor space.

The Zooz ZSE44 XS SENSOR Temperature and Humidity Sensor has severe limitations that make it a poor choice. The readings are inconsistent, and the range is so limited that it struggles to monitor even small spaces effectively. Setup was easy, but the lack of reliability negates that advantage. Other customers should know that it often fails to connect properly and doesn’t deliver on its promises—honestly, with these issues, it shouldn’t even be sold. I’d recommend looking for a more dependable alternative.

Not compatible with Alarm.com Z-Wave. If it is, then it's extremely difficult to pair. do not waste your time on this device.
