SONOFF Firmware

ITEAD‘s SONOFFs are Wi-Fi enabled relays that can be used to turn applicances on and off remotely.

The firmware they come with did not suit my needs so I wrote and flashed my own. This can be achieved easily since the SONOFFS are built around an ESP8266 chip, which can be programmed with the Arduino IDE.

Here is a list of functions that the custom firmware features:

• MQTT support with JSON payloads
• REST API
• Control through web interface
• Update through web interface
• Update using Arduino OTA

Source code available on GitHub.
