E-ink technology is typically found in devices like the Amazon Kindle, and it is also a critical feature of the Qingping thermometer. I originally reviewed the Bluetooth version of this device a few years ago, but Qingping has since updated it with Thread support for Apple Home. I have been retesting it to see if it still holds up in 2026.

Why individual room sensors matter
In my ideal world, every house would have a variable HVAC system capable of heating and cooling rooms independently. Since a full system replacement is rarely in the budget, the next best thing is having granular data on what is actually happening in individual spaces. I recently forgot to set my upstairs Nest back to Eco mode, and the temperature difference in my son’s room was shocking. Relying on a single hallway thermostat simply does not work for an entire house. That is why I rely on localized temperature sensors to trigger smart plugs and fans.
