Description

The Sonoff TH16A is a versatile smart switch that combines high-current relay control with environmental monitoring capabilities. It operates on standard 100-240V AC power and connects to your local Wi-Fi network, enabling remote on/off control and real-time status tracking of connected devices through the eWeLink mobile application.

Its core function is to act as a trigger based on temperature or humidity readings from an external sensor. You can preset specific ranges, and the switch will automatically turn connected appliances like fans, heaters, or humidifiers on or off when thresholds are met. This makes it ideal for climate control automation in homes, greenhouses, or server rooms. The device supports creating complex Smart Scenes to interact with other Sonoff devices in your ecosystem.

Key Features

  • High-power relay for controlling AC appliances up to 3500W (15A).
  • Integrated Wi-Fi (802.11 b/g/n) for cloud connectivity and remote management via eWeLink.
  • External sensor port for connecting precise temperature/humidity probes (Si7021, DS18B20, DHT11, AM2301).
  • Advanced automation with configurable Smart Scenes, countdown timers, and scheduling.
  • Voice control compatibility with Amazon Alexa and Google Assistant.
  • IFTTT applet support for creating custom web-based automation workflows.
  • Real-time monitoring of switch status and sensor data from your smartphone.
  • Compact, wall-pluggable design with ABS plastic housing.

Applications

  • Smart home climate control for heaters, fans, air conditioners, and humidifiers.
  • Automated greenhouse or hydroponic system management.
  • Server rack or network closet overheating protection.
  • Aquarium or terrarium environmental monitoring and automation.
  • Energy-saving automation for baseboard heaters or space heaters.

Frequently Asked Questions

What sensors are compatible with the Sonoff TH16A and how do I connect them?

The TH16A supports external digital sensors including the Si7021, DS18B20, DHT11, and AM2301. These are not included. You must connect the sensor's data, power, and ground wires to the designated screw terminals on the switch before applying AC power. It is critical to wire the sensor correctly prior to powering on the device to prevent damage.

How do I set up the TH16A with the eWeLink app and configure automation rules?

Power the switch, put it into AP pairing mode, and connect via the eWeLink app. Once connected to your Wi-Fi, you can add a compatible sensor. In the device settings, create a 'Smart Scene' where you define a trigger (e.g., temperature > 25°C) and an action (e.g., turn switch ON). You can also set repeating timers or countdowns directly for the relay.

What is the maximum load the TH16A relay can handle, and can it control inductive loads like motors?

The relay is rated for 15A at 250VAC, with a maximum resistive load of 3500W. While it can control motors or compressors (inductive loads), the inrush current must be considered. For safety and longevity, it is recommended to derate the maximum current for inductive loads or use an external contactor for heavy-duty equipment like well pumps or large air conditioners.
