WREN | ESP32-C5 Recliner Linear Motor Controller | IoT Home Automation | RS485-DMX

Description

WREN, is a compact, Linear Motor Controller which can be easily integrated into IoT Home or Industrial Automation systems, via 2.4 GHz, or 5 GHz Wi-Fi.

The design is in operation around the World and is straight forward to install.  It has been updated for 2026!

The WREN SDK board:

• Is designed to easily, and safely, retrofit (plug and play), to industry standard Electric Reclining Chairs.
• Allows continued use of any existing push buttons, or remote hand controller, through isolated input and outputs.
• Enables simultaneous electrical control from Smart Home Automation.
• Includes electronic Hardware Safety Lockout and Shutdown.
• Designed for standard 5 Pin DIN connections, typically used for Electric Recliners
• Although most chairs operate at 24 V DC, WREN could be used on systems from 9V to 48V DC.
• The WREN Dual Linear Motors Controller can be internally linked to provide increased single motor current control – heavy duty.
• RS485 Interface for chaining controllers, such as Home Cinemas.
• DMX / DMX512 Lighting and Audio Automation Control.

Home or Industrial Automation, IOT control, could be local, or cloud based, to suite the users needs.

• Can be used to control a range of Linear Motors:
  • Electric Recliner Chair
  • Electric Recliner Bed
  • Greenhouse Vent Windows
  • Solar Panels, Tilting and Sun Tracking
  • Stage Automation
  • Animal Flaps
  • Optical Tracking
  • Robotics
