Three small green circuit boards with black relay cubes and silver ESP-01 modules

Mimo Tech

Mimo Tech 3pcs 5V ESP8266 Dual WiFi Relay Module Smart Hub

SKU CH-W626-6MYDK

Three 5 V ESP8266 dual-channel Wi-Fi relay modules for app-based smart-home switching up to 10 A at 250 V AC or 30 V DC

  • Connection protocolHomekit
  • Product typeAutomation Hub / Controller
  • Control two circuits from your phone using the ESP8266 WiFi module
  • Works in direct phone-to-module mode or through your home router
  • Includes three 5V dual relay modules for multi-room automation
  • Each relay handles 10A at 250V AC or 30V DC with 100000-cycle endurance
  • Functions as a USB relay when the ESP-01 module is removed

Three-piece Wi-Fi relay kit

The Mimo Tech 3pcs 5V ESP8266 Dual WiFi Relay Module Smart Hub provides three independent automation controllers for home IoT projects. Each unit integrates an ESP8266 wireless module with a dual-channel relay board, allowing mobile app control of two separate circuits per device. The kit targets hobbyists and installers building custom smart-switch panels or retrofitting existing appliances.

On-board relay specs and power options

Every module carries two 5 V relays rated at 10 A / 250 V AC and 10 A / 30 V DC with diode protection and a claimed 100000-cycle endurance. The board can operate as a USB relay when the ESP-01 module is removed, and status LEDs indicate mode selection and relay state. Two wireless modes are supported: direct phone-to-module connection up to 100 m in open air, or router-bridged operation where range follows the router signal.

Checks before ordering

Verify that the controlled loads stay within the 10 A per channel limits and that a stable 5 V supply is available for each board. The modules use the Homekit protocol, so confirm compatibility with your preferred automation platform and mobile app. Ensure the installation location provides adequate wireless coverage for the chosen mode, and plan for UART debug access if custom firmware work is intended.

Questions about this item

What does the HomeKit protocol actually cap in practice for this module?

The module exposes its two relays to Apple HomeKit, letting you toggle each 10 A / 250 V AC or 10 A / 30 V DC circuit from the Home app or Siri; no other HomeKit device types are advertised.

What physical space and power connections does each board need to fit and mount?

Each board carries an on-board 5 V relay rated for 10 A, an ESP-01 socket, an N76E003 or STM8S003 MCU, model-selection and status LEDs, and a preserved UART debug header; allow room for the relay body and wiring terminals.

How is the module installed, and which step do people get wrong?

Power the board with 5 V, connect the two relay outputs to your loads, then use the SmartConfig feature in the phone app to join the ESP-01 to Wi-Fi — either direct phone-to-module (Mode 1, up to 100 m open air) or via your router (Mode 2); a common mistake is skipping the SmartConfig step and expecting the relay to appear automatically.
