Review on 🌡️ Enhanced Qingping Bluetooth Digital Thermometer Hygrometer Sensor Compatible with HomeKit (Exclusive for iOS), Wireless Indoor Temperature and Humidity Monitor with E Ink Display for Home by Jeff Pettis

Love Love Love the e-ink screen on this thing! Much sharper and crisper than the pictures show! The ideal arrangement is a higher temperature # over a lower humidity #. And the form factor is clean, simple, modern-looking and room-readable. The only flaw is the attachment tab. The thermometer itself has powerful magnets that stick strongly to anything magnetic, but the mounting tab itself contains so little metal that the thermometer falls off its mount every time someone walks past it. You can stick a piece of magnetic tape on each wall for a better grip. Bluetooth isn't required (so I didn't try it), but in general I'm a fan of this stuff!
