nodemcu_sonoff

Nodemcu based code for Sonoff WiFi smart switch.

Features:

• MQTT relay switch control
• MQTT and HTTP device monitoring: switch state, device IP, uptime.
• The button on the device can also be used to toggle the state of the switch (On/Off)
• WiFi connection state monitoring and auto reconnection to the same/backup network.
• Telnet remote console and OTA update.

Description:

• default_config.lua : some example of the configuration file. Copy to config.lua, edit with your options and upload to the device;
• init.lua : runs the WiFi connection and launches other modules;
• ota.lua : simple HTTP-server;
• telnet.lua : simple telnet server for remote console and on the air (OTA) update;
• broker.lua : MQTT client module.

mosquitto_pub -h "myMQTTserver" -t "/myMQTTpath/power" -m "ON" -- turn switch on
mosquitto_pub -h "myMQTTserver" -t "/myMQTTpath/power" -m "OFF" -- turn switch off

• install.sh : script for easy nodemcu firmware programming and source files upload

Requarements:

4refr0nt/luatool - tool for loading Lua-based scripts from file to ESP8266 with nodemcu firmware. espressif/esptool - tool for communication with the ROM bootloader in Espressif ESP8266.

First install:

If you have new out-of-the-box sonoff WiFi smart switch, just connect it to the PC with 3.3v USB-to-TTL adapter, switch it on with the button pressed, then run:

./install.sh /dev/ttyUSB0

OTA update:

luatool.py --ip <your IP-address>:23 --src <path to file> --bar

Main project structure and original code was taken from elric91/nodemcu_sonoff Safe modules load stolen from DasBasti's fork Nodemcu firmware generated with Marcel's NodeMCU custom build machine (just add MQTT to the standard module selection)
