Let me start by saying this little gadget has been a game-changer for my smart home setup. The ARRE sensor nails the basics—temperature readings are scarily accurate (I cross-checked with 3 other thermometers), and humidity tracking is reliable enough to automate my baby’s room humidifier flawlessly.

What surprised me? Its Thread support. Pairing with Apple Home/Google Home was effortless, and updates every 2 minutes feel snappy compared to Bluetooth sensors I’ve used. The CR2032 battery life? Mine lasted 3 months (not the advertised year), but replacements are cheap.

Now, the quirks: The magnet stand is laughably weak—mine now sits on a shelf after multiple falls. The air pressure readings were comically wrong (21.2 inHg vs. actual 29.9), though ARRE’s support team is actively fixing this via firmware updates.

For Google Home users: Beware! You’ll only see Celsius temps without decimals due to Google’s Matter implementation lag. Also, my unit’s humidity sensor drifted ~15% over time—fine for general monitoring but not for precision needs.

Verdict? At this price point with Matter/Thread support, it’s a solid pick despite flaws—just don’t trust it for weather forecasting or critical humidity control!
