Tuya WiFi Temperature Sensor Thermometer Detector - Smart Life Remote Monitor & Alarm (Freezer Test, Energy Saving)

Overview: This Tuya-compatible KONLEN temperature sensor provides real-time temperature monitoring and sends alerts to your phone when readings fall outside preset limits. Use the Tuya Smart or Smart Life app for remote supervision, unit selection (°C/°F), history export and sharing with multiple users.
