    This product is available in different Z-Wave frequencies so please make sure you choose the correct region before checking out. You need to select the same frequency / region as your hub when buying Z-Wave devices for them to include to your system. If you're not sure which frequency your hub operates on, please contact your solution provider first. Here is what each option stands for:

    • US/CA/MX: 908.42 MHz (used primarily in US, Canada, and Mexico, the default option for all products)

    How It Works

    This sensor is perfect for spot monitoring in spaces where your smart thermostat doesn't reach. Install the device in your bedroom to prepare just the right temperature for the night. Mount it in the basement or on your sun porch to trigger climate control device and keep the air constant where humidity and temperature is most likely to change quickly.

    Just stick it to the flat surface of your choice with the supplied adhesive tape for 1-minute installation. We recommend using the dedicated mounting bracket if you'd like to install the sensor outdoors. Always keep the device out of direct sunlight and rain or snow.

    Humidity Sensor ZSE44 800LR

    I have quite a few ZSE44 700 and now the 800LR installed in different locations and they are very accurate and responsive. I have integrated many of the ZSE44 with the Heating and Air thermostats and air vent fans and I am very pleased with the quality and price of these devices.

    Excellent temperature and humidity sensors

    Small sensors and seem accurate, include nice mount. Use them to control our bathroom exhaust fans using the humidity function. Zooz is always a good purchase for Z-wave products!

    Small, pairs easily, comes with bracket

    This pairs easily with the QR code, is nice and compact, and comes with a mounting bracket, and is a great price.

    Work great - use them to guage fridge temperature

    Was having an issue with a garage fridge that would stop working and we would loose food, stuck this in to give us warnings whenever temperature dipped in fridge or freezer- worked great

    SE44 is a Great Sensor

    Using these to monitor temperature in my boat and in an automation to enable a bilge heater. Worked flawlessly this past Winter.
