XY-WFWT WiFi Temperature & Humidity Relay Controller Module
XY-WFWT WiFi Temperature & Humidity Relay Controller Module
Take full control of your environment with the XY-WFWT WiFi Temperature and Humidity Relay Controller Module. Designed for hobbyists, engineers, and automation enthusiasts, this compact dual-output module lets you remotely monitor and automatically regulate temperature and humidity — all from your smartphone or smart home setup via WiFi. Whether you're managing a greenhouse, server room, storage space, or DIY climate control project, the XY-WFWT keeps conditions precisely where you need them.
Key Features
- Dual Relay Output: Independently controls both temperature and humidity equipment simultaneously — heat/cool and humidify/dehumidify in one unit.
- Wide Sensing Range: Monitors temperature from -20°C to 60°C and humidity from 0% to 100% RH with precision accuracy of 0.1°C / 0.1% RH.
- Smart Auto Mode Recognition: Automatically detects whether to activate heating or cooling, humidification or dehumidification, based on your configured start/end setpoints — no manual switching required.
- WiFi Remote Control: Set thresholds, monitor live readings, and receive alerts remotely via the companion app over your WiFi network.
- Integrated Sensor: Built-in detection probe for streamlined installation — no external sensor wiring needed.
- High-Capacity Relay Output: Supports up to 10A load, compatible with a wide range of heating, cooling, humidifying, and dehumidifying appliances.
- Visual Indicator: Red LED indicator clearly shows when the relay is active, giving you instant at-a-glance status.
- Low Voltage Safe: Operates below 50Vac or 75Vdc, meeting EU LVD safety standards.
How It Works
Temperature Control
- Cooling Mode: Relay activates when sensor temperature reaches or exceeds the set start temperature; deactivates when temperature drops to or below the set end temperature.
- Heating Mode: Relay activates when sensor temperature drops to or below the set start temperature; deactivates when temperature rises to or above the set end temperature.
- Mode is automatically selected based on whether the start temperature is higher (cooling) or lower (heating) than the end temperature.
Humidity Control
- Dehumidification Mode: Relay activates when sensor humidity reaches or exceeds the start humidity setpoint; deactivates at or below the end setpoint.
- Humidification Mode: Relay activates when sensor humidity drops to or below the start humidity setpoint; deactivates at or above the end setpoint.
- Mode is automatically selected based on your configured start/end humidity values.

Frequently Asked Questions
Q: What devices can I control with the XY-WFWT WiFi relay module?
A: The XY-WFWT can control any compatible heating, cooling, humidifying, or dehumidifying appliance with a load of up to 10A. Common uses include space heaters, cooling fans, air conditioners, humidifiers, dehumidifiers, greenhouse climate equipment, and more.
Q: Does the XY-WFWT require an external sensor or probe?
A: No — the XY-WFWT features a built-in integrated sensor for both temperature and humidity detection, simplifying installation without the need for external probes or additional wiring.
Q: How does the automatic mode recognition work on the XY-WFWT?
A: The module compares your configured start and end setpoints. For temperature: if start is higher than end, cooling mode is activated; if start is lower, heating mode is used. For humidity: if start humidity is higher than end, dehumidification mode activates; if lower, humidification mode is used. This happens automatically with no manual switching required.
Q: Can I monitor and control the XY-WFWT remotely?
A: Yes. The XY-WFWT connects to your home or facility WiFi network, enabling remote monitoring of live temperature and humidity readings and remote adjustment of control setpoints through the companion app from anywhere with an internet connection.
