Description

 

WREN is based on the popular ESP8266, in order to easily control Linear Motors in Electric Reclining Chairs and Beds, from a Home Automation system.

Add Comfort to your Home Automation – This is a Smart Home Device

WREN, is an IoT Linear Motor Controller board.

It was initially designed to easily, and safely, retrofit (plug and play), to industry standard Electric Reclining Chairs, with continued use of existing push buttons (or remote hand controller), through isolated input and outputs, whilst also allowing simultaneous electrical control from Smart Home Automation.

  • Elderly Assistance
  • Mobility Aid
  • Empowering the Disabled
  • Home Cinemas
  • Gentle Exercise Control
  • Lounge Gadget

Based on the Ai-Thinker ESP-12S (ESP8266), WREN has seen integration into a number of other interesting applications including, Elderly Assistance, Mobility Aid, Empowering the Disabled, Multi-chair Home Cinemas, Gentle Muscle Exercise Control and of course the humble Lounge Chair Gadget. Through the flexible design and integrated dual-bridge motor controller, the DitroniX WREN SDK allows for a range of other single, or dual, DC Linear Motor applications, such as used in electric beds, shutters, blinds, vents and windows.

The WREN-2 board has a wider operating voltage range of 9v to 38V, in order to expand use cases. The existing features remain, such as single, or dual, linear motor control at max 5.6A max RMS Load Current, array of safety circuitry and ability to operate from the existing 24-29V DC supply provided by the reclining chair, or host. In addition, the PCB outline has been designed to neatly fit into an inline enclosure, complete with cable grips, so making this a complete and safe solution.

Development of ESP8266 software is fully supported through IDE such as Arduino IDE, Platform IO, Eclipse etc. WREN maybe integrated in a variety of home automation technologies such as ESPHome, Tasmota, HiveMQ, ESPEasy, ST Anything, SmartThings, Node-Red, Home Assistant, MQTT, CloudMQTT, IFTTT, Mosquitto, Domoticz, etc.

Top level differences between older WREN-1 verses new WREN-2

  • Increased operating voltage range, 9V to 38V (was 12V to 30V)
  • Increased DC motor current to 5.6A RMS (was 2.8A RMS)
  • Additional Safety Circuitry (allows increased range of uses)
  • Additional Developer User Configuration
  • Additional EMC Filtering (for when used in high electrically noisy environments)
