About This

• Reliable Bluetooth Connectivity for Local Monitoring:This indoor bluetooth temperature sensor maintains a stable connection via Bluetooth to the Smart Home App, allowing you to easily monitor real‑time temperature and humidity data directly on your smartphone when within range—no Wi‑Fi setup or internet access required.
• Face Icon Comfort Indicator: Instantly assess your environment with the clear face icon display on this remote temperature monitor.

Improved product quality supports an extended battery life of approximately 12 months using a button cell battery.
