DieseRC 4-Channel WiFi Smart Switch Relay Module — 4 Independent Relays, Alexa & Google Home Compatible

Meet the DieseRC 4-Channel WiFi Smart Switch, a compact relay hub designed to bring four independent dry-contact outputs under your remote control. Built to handle a wide DC range, it supports 5V up to 48V, empowering you to automate lights, doors, and small devices with precision. When you pair it with the eWelink app, Alexa, or Google Home, you gain effortless, hands-free control without sacrificing reliability.

Smart control that fits your life

• Four independent relays provide separate switchable channels for different devices or circuits.
• Passive output (dry contacts) ensures flexibility for a variety of loads and configurations.
• Compatible voltage range (DC 5V–48V) makes it suitable for hobby projects and small automation tasks.

Operation is designed to be simple and adaptable. Choose between inching (momentary) and self-locking (toggle) modes to match your project’s needs. A compact footprint means it can tuck neatly into most electrical boxes, keeping your installation tidy and discreet.

Smart features that expand your possibilities

• Remote control via the popular eWelink app on Android and iOS.
• Voice control compatibility with Amazon Alexa and Google Home for hands-free scenes and routines.
• Scheduling and timer functionality lets you automate timing-based actions without manual input.

Beyond basic control, you can share access with family members, enabling synchronized automation across a household or workspace. The device also supports optional Bluetooth remote control (RM2.4G) for local, wireless triggering when you’re nearby.

Real-life uses and installation

Imagine automating a garage door opener, controlling a lamp and a small fan from a single hub, or integrating a door lock into a smart routine. This module is intended for homes, offices, farms, laboratories, and shops where dependable, flexible control of multiple loads matters. The 65×48×17 mm form factor is designed to slide into standard junction boxes, making installation straightforward for DIY enthusiasts and pros alike.

What to expect during setup

• Four relays with clearly defined normally open, common, and normally closed terminals support versatile wiring.
• The device is designed for dry-contact operation with a broad DC input range for broader compatibility.
• Easy pairing with eWelink, and seamless voice control through Alexa or Google Assistant.

While it emphasizes user-friendly configuration and flexible control, it remains a hands-on automation component best paired with careful cable routing and safety-conscious wiring practices. Consider this a smart, expandable building block for your automation projects rather than a standalone smart home solution.
