This is a demo application used to toggle on/off up to 4 relays connected to an ESP8266 board or similar device (such as an Arduino with a wi-fi or ethernet shield, a picmicro or other mcu enabled to access your local network).
Once you've got a working interface connected it to your local network and you know its IP address, you can connect to your board using Relay Remote to switch on and off 4 I/Os to which you've connected relays.
A complete tutorial on board specifications and usage is available on my blog (www.settorezero.com) at this url: http://bit.ly/2exrtFS
You can edit name of relays and IP address to suit your application (in "settings" screen).
this application is for demonstrative purposes only. Is not suitable for toggling devices outside your local area network since connection is not protected. Author will not responsible for any damage.
