ESP Easy

ESP Easy is an interesting piece of firmware, it really makes interfacing to an ESP 8266 a breeze. It has a very comprehensive user interface to configure practically everything:

1. MQTT setup
2. All the GPIO pins behaviour.
3. Configure the supported sensors setting.
4. Configure the OLED to display the value of the sensors.
5. and more...

In this setup, I used my custom Wemos D1 Mini shield extender to connect to additional I2C devices. I have connected to a BMP280 temperature/pressure sensor and a TSL2561 luminosity sensor. For fun, I have also connected the DHT11 temperature/humidity sensor.

All this setup is done without writing a single line of code. Amazing. Kudos to ESP Easy. One interesting observation, the temperature reading from DHT11 and BMP280 differs by abt 1.5 to 2 C. I wonder which sensor is accurate?
