Customers find the temperature and humidity sensor to be excellent, with a clear display that’s easy to read. The connectivity and accuracy receive mixed feedback – while some report successful pairing with Aeotech hubs, others mention it disconnects randomly and isn’t very accurate. The compatibility works well with Hubitat but doesn’t work with Hubitat C8 Pro, and while the display visibility is generally good, some report issues with the screen going blank. Battery life and temperature monitoring also get mixed reviews, with some praising its amazing battery life while others report it doesn’t stay connected, and some noting it can’t read temperatures below 14.4°F.
