Get your Sonoff Basic working with Blynk

Primary LanguageC++

Sonoff_Basic_Timer

Why?

  • Lets start with that the Sonoff Basic devices are cheap. At the current time they can be purchased for about $4 each. They include wifi, 120v to 5v power, a 10A relay, one button, one LED and the ability to run on mains power.

  • For what they offer you get a lot, but you need to be connected to the internet 100% of the time. A primary requirement for me was to host the server myself and if I wanted a cloud service there was an option to connect to one.

  • I was looking for a way to have many, 10 or more, timers for different things.

  • Was there other option besides Blynk, yes but they seemed a lot more involved to get up and running.

What?

  • This code should be a quick replacement on the Sonoff Basic.

  • You should be able to add your WiFi, Blynk Server, and Auth token, flash the code to the Sonoff Basic and be ready to connect to your Blynk Server.

  • Is this code feature compelete, NO. Lots of little things need to be done. Sunrise/Sunset timers, Alert Mode, Manual Mode, IFTTT integration, and more...?

  • What would you like to see added? How are you using it?

How it should work

  • Button on Sonoff turns on and off the relay, status LED is YELLOW.

  • In App Button turns on and off the relay, status LED is ORANGE.

  • You can turn on with the button and off with the app, or on with the app and off with the button. Status LED reflects where you turned it on.

  • Timer set will turn it on and off, status LED BLUE.

  • Manually turn on the Relay and have the time turn it off at some point in the future.
