Sonoff Firmware with MQTT
Sonoff Firmware with MQTT and Multiple incoming topics and support for DHT22 sensor.
Topic is the main MQTT topic that turns the relay on and off
Topic2 is a second incoming MQTT topic that allows you to turn the led on and off.
When button is pressed it publishes a to MQTT topic this allows you to handle the press in OpenHAB or Node-Red
This firmware also allows you to hook a DHT22 sensor up to the extra GPIO pin (14) on the Sonoff and get temperature and humidity readings via a MQTT topic.
This is a simple sketch for sonoff devices that allows MQTT. This is based off of https://github.com/SuperHouse/BasicOTARelay but I
customized for my needs
