Mobile Phone Remote Control Relay Module for Smart Home Automation

This remote control relay module lets you manage electrical devices directly from your smartphone using a dedicated app. It solves the problem of needing to be physically present to flip a switch — ideal for controlling lights, pumps, fans, or other appliances in your home or workspace. The module supports a broad DC supply voltage range from 6V to 36V, so it works with many common low-voltage power sources. Whether you are building a custom smart home system or automating a single device, this relay provides a simple and effective solution without complex wiring.

Features and Construction

The module is built as a compact electronic relay board designed for integration into existing setups. It uses WiFi connectivity to communicate with your mobile device through the smart home app.

Material and Build

The module consists of standard electronic components mounted on a circuit board. No specific materials or case details are given in the source text, but the unit is intended for indoor use in a dry environment. The PCB is likely FR4 glass epoxy, typical for such modules.

Size and Practical Fit

Exact dimensions are not provided in the source text, so the module's footprint is unknown. However, similar relay modules are typically compact, fitting inside small junction boxes or enclosures. Plan your mounting space with the understanding that exact size data is not available.

Uses and Placement

This relay module is suitable for a variety of remote-control applications where you want to switch a low-voltage DC circuit. It is particularly useful in smart home projects, DIY automation, and remote equipment management.

Event or Professional Use

Professionals can use this module to remotely control lighting or signage in temporary installations such as trade shows or exhibitions. The app-based control reduces the need for manual intervention, saving time and effort.

Everyday Home Use

In a home setting, you can connect it to a lamp, water pump, or garage door opener. The app allows you to turn devices on or off from another room or while away, adding convenience to daily routines.

Benefits and Buying Value

The main advantage of this module is its straightforward mobile control and wide voltage compatibility. It avoids the need for proprietary hubs or complex programming, making it accessible for beginners and experienced users alike.

Reuse and Low Maintenance

The module is designed for long-term use with no moving parts apart from the internal relay. Maintenance is minimal — keep it dry and within its voltage limits. The APP may require occasional updates, but the hardware itself is largely set-and-forget.

Why Choose This Product

Choose this relay module if you need a simple, app-controlled switch that works with a wide range of DC voltages (6V-36V). Its compact design and wireless connectivity make it a practical choice for adding remote control to almost any low-voltage device.
