SONOFF THS01 Temperature and Humidity Sensor

【Equipped with ESP32 – Smarter Core, Better Performance】Equipped with the new-generation ESP32 chip, BASICR4 delivers faster response, more stable connectivity, and enhanced processing power — all while keeping it cost-effective for your smart home setup. 【Magic Switch Mode – Smart Even When Wall Switch is Off】Thanks to its unique Magic Switch Mode, you can still control your lights from the app, even if a traditional wall switch has been turned off. Enjoy continuous remote access and automation. 【Built-in eWeLink-Remote Gateway – Unlock Local Two-Way Control】As a gateway device for eWeLink-Remote, BASICR4 lets you pair with S-Mate2, R5, and other remote sub-devices. Set up two-way or multi-way control, and enjoy low-latency local control without relying on Wi-Fi. 【Group Control – Smarter Management of Multiple Devices】Easily group your devices by room or scene, and control multiple switches simultaneously via app. Save time and simplify your daily routines. 【Certified Safety with Real-Time Thermal Protection】Features a built-in temperature sensor that continuously monitors internal heat levels. Automatically cuts off power in case of overheating, protecting your home from risks like deformation, fire, or exposure of live wires. Certified by CE, FCC, ETL, and more.

【Wide Lighting Compatibility】Supports dimmable LEDs up to 200VA, incandescent and halogen lamps up to 400W, and dimmable electronic transformers up to 200W, covering a wide range of residential lighting types. 【Matter Smart Ecosystem Support】Matter-enabled for seamless integration with Apple Home, Google Home, and Amazon Alexa, enabling cross-platform automation, smart scenes, and hands-free voice control. 【Smooth Calibrated Dimming】Automatic or manual calibration ensures the dimmer is better adapted to your lighting fixtures, identifying the actual brightness response range of the fixtures for stable, flicker-free dimming. 【Real-Time Power Monitoring】Continuously detects and synchronizes power consumption data, giving clear insights into real-time energy usage. 【Built-In Overheat Protection】Integrated temperature detection triggers UI alerts and automatically cuts power output when overheating occurs, protecting both the device and connected lighting. Note: 220–240V only. Do not exceed or go below voltage limits.

【Split Core Current Transformer – Non-Invasive & Safe Monitoring】Measure current up to 100A with a split-core clamp design — no need to touch live wires. Just snap the CT sensor open or closed via side latches for quick and safe installation, ideal for both DIYers and professionals. 【Real-Time Energy Monitoring – Room or Circuit Level Insight】Install POWCT in your home’s electrical panel to monitor power usage by room, circuit, or heavy-duty appliances. Identify energy waste, optimize power consumption, and gain full control over your electricity usage. 【Track Exported Power to the Grid – Optimize Solar Efficiency】POWCT is more than just an energy monitor—it’s a smart solution for tracking bidirectional power flow, including energy exported back to the grid. When integrated with solar inverters or battery storage systems, it provides real-time data on surplus electricity generation, helping you maximize self-consumption, reduce waste, and improve your return on investment from solar power. 【6-Month Historical Power Data – Auto Save & Exportable】Review hour-level electricity data for up to 6 months, and you can export it as files for energy analysis or reporting. 【Dry Contact Relay – Contactors & Load Control Supported】Equipped with a 2A dry contact output, POWCT can be connected to an external contactor to switch large electrical loads on or off. Perfect for industrial applications or smart energy management systems.
