    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.

    Love these little things

    These sensors were easy to install and work fantastic battery. Life is excellent.

    Michael G
    Simple, Effective and Wife-approved

    The device was simple to install, configure and works as advertised, without nuance. Readings are accurate and updated promptly with the default polling and settings. The sensor itself is aesthetically pleasant and discretely blends in with any white or ultra-white wall/ceiling. It comes with several mounting options making this one of the more hassle-free devices I've added to my smart home.

    Everything you expected…

    Easy to order, fast shipping, great products at great prices, and great product documentation. I plan to order more.

    Works as advertised

    Distributed several of these throughout my home. Easy pairing with Home Assistant.

    Only works up to 104 degrees Fahrenheit

    These are only good for 32 to 104 degree operating range.

    It is my fault that I overlooked that the new 800LR series only has an operating temperature up to 104 degrees Fahrenheit (and the Silicon Labs that makes the 800 series chips claims they only work up to 95 degrees F). Would not have bought them if I looked a little deeper into this since I need them for the attic to control a fan where it gets hotter than 104 (95) degrees. Really silly that the cost engineers on this product cheaped out and went with a 36-104 degree F operating range.There are cheaper alternatives that have a much wider operating range on the market if you go with Zigbe communication protocol... not sure about Z-Wave.

    Thank you for your feedback, Jim! That is correct that this is a Z-Wave chip limitation; we do note the operating temperature on the product page as well as in the device specifications. Please let us know if you have any questions going forward!
