A new level

Easy to connect, long battery duration but it is possible to pair with sonoff valve what take the product to a higher level. I have one outside and comparible with google home what le me create automarions. Only point to improve, inteface with google home doent show temperature and humedity in the same screen... Fine tuning to be done here in the interface with google home, borh data in the same screen would be the correct settting in my view.

Shockingly affordable for a device with a display

These are handy to put anywhere you are interested in monitoring the environment. The display is large and easy-to-read. Includes what you need to mount it. Use of a CR2450 promises much longer life than the more typical CR2032 - has about 2.5x the capacity.

SNZB-02D

Great update of the SNZB-02. Accurate and nice to be able to read the temperature without using the app. Also great idea with the magnet and a stand if you want to move it around.
Great little gadget that also can be used to control indoor climate using automation.

Zigbee AND a display! Best of both worlds

I love these units. Quick switch between F and C, easy to read display, and remote abilities with Zigbee. Wall mount or stand. I can see more of these in my future.
