Sonoff TH10 Mobile Temperature Switch Timing Thermostat Temperature and Humidity Controller
Sonoff TH10 Mobile Temperature Switch Timing Thermostat Temperature and Humidity Controller
The Sonoff TH10 is a WiFi-enabled smart temperature and humidity monitoring device that functions as an intelligent thermostat controller with mobile app integration and programmable timing capabilities. HVAC technicians, laboratory managers, and industrial facility operators use this device to maintain precise environmental conditions and automate climate control systems remotely. It solves the critical problem of manual temperature monitoring and delayed response to environmental fluctuations by providing real-time sensor data and automated switching logic accessible from any smartphone.
Product Overview
The Sonoff TH10 operates on a dual-sensor architecture combining a DHT11 temperature and humidity sensor with a high-sensitivity relay module rated for 10A at 250V AC. The device communicates via 2.4GHz WiFi connectivity to the eWeLink mobile application, enabling users to set temperature thresholds and humidity parameters that trigger automatic relay switching. The internal microcontroller processes sensor readings every 10 seconds and compares them against user-defined setpoints, executing relay activation or deactivation based on hysteresis logic to prevent relay chatter and extend component lifespan.
What distinguishes the TH10 from basic thermostats is its combination of mobile accessibility, programmable timing schedules, and dual-parameter control. Users can establish independent temperature ranges for heating and cooling modes, set weekly schedules for different temperature profiles, and receive push notifications when thresholds are exceeded. The device supports both local network control and cloud-based remote access, with backup functionality that maintains programmed settings during WiFi disconnection. The compact DIN-rail mountable form factor makes it suitable for integration into existing electrical panels without requiring extensive rewiring.

How to Use
Begin setup by switching off power to the circuit where the TH10 will be installed. Mount the device on a DIN rail within your electrical panel, ensuring the temperature sensor probe is positioned away from direct heat sources and in representative air space. Connect the AC power supply terminals to your 110-240V input, then wire the relay contacts (Common, Normally Open, Normally Closed) to your load device such as an air conditioning unit or heater. Power on the device and wait for the WiFi indicator LED to blink, indicating it is in pairing mode.
Download the eWeLink application on your smartphone and create an account if you do not have one. Scan the QR code on the TH10 device or manually enter the 8-character code to add it to your account. Once connected, configure your temperature thresholds by setting the upper limit for cooling activation and lower limit for heating activation. Establish your humidity control parameters, set weekly schedules for different temperature profiles, and enable push notifications for threshold breaches. Test the relay by manually triggering it through the app to confirm proper wiring and load operation before deploying the device in production environments.
Frequently Asked Questions
What is the maximum load capacity of the TH10 relay, and can it directly control air conditioning units?
The TH10 relay is rated for 10A at 250V AC, which allows direct control of most residential air conditioning units drawing up to 2.5kW. However, for commercial or industrial AC systems exceeding this capacity, use the TH10 as a control signal to trigger a contactor or relay with higher amperage rating. Always verify your AC unit's current draw specifications before direct connection to avoid relay burnout.
How accurate are the temperature and humidity sensors, and how often does the device take readings?
The DHT11 sensor provides ±2°C temperature accuracy and ±5% relative humidity accuracy. The device samples both sensors every 10 seconds and compares readings against your configured thresholds. For applications requiring higher precision such as pharmaceutical storage, consider supplementing the TH10 with external calibrated sensors and data logging systems.
Does the TH10 continue functioning if WiFi connection is lost?
Yes, the TH10 maintains all programmed settings and continues executing temperature and humidity control logic during WiFi outages. The device stores your threshold parameters and timing schedules in non-volatile memory, so relay switching continues based on sensor readings. Once WiFi reconnects, the device synchronizes with the cloud and resumes sending notifications and accepting remote commands through the eWeLink app.
Can I set different temperature ranges for heating and cooling, and can I create separate schedules for weekdays and weekends?
The TH10 supports independent heating and cooling setpoints, allowing you to configure a lower threshold that activates heating and an upper threshold that activates cooling. The eWeLink app provides weekly schedule templates where you can set different temperature profiles for each day of the week, enabling energy-efficient operation that adapts to occupancy patterns.
