Edimax: Smart Plug Control

Smart Plug control for Edimax models SP-1101W, SP-2101W et al

Version 2.0 by Michael Balzer <dexter@dexters-web.de>

Note: may need HTTP.request() digest auth support to work with newer Edimax firmware (untested)

The smart plug can be bound to a defined location. Automatic periodic recharging or charge stop can be configured via main battery SOC level and/or 12V battery voltage level. The plugin can also switch off power at the charge stop event of the main and/or 12V battery.


  1. Save edimax.js as /store/scripts/lib/edimax.js
  2. Add line to /store/scripts/ovmsmain.js:
  • edimax = require("lib/edimax");
  1. Issue script reload
  2. Install edimax.htm web plugin, recommended setup:
  • Type: Page
  • Page: /usr/edimax
  • Label: Edimax Smart Plug
  • Menu: Config
  • Auth: Cookie
  1. Install edimax-status.htm web plugin, recommended setup:
  • Type: Hook
  • Page: /status
  • Hook: body.post

The edimax-status.htm plugin adds power control to the Status page’s vehicle panel.


Use the web frontend for simple configuration.
