The second episode of ESP8266 programming series. In the next video I describe how to code a firmware for ESP8266 using Arduino IDE. The purpose of that firmware is create a temperature sensor and publish the reading in a MQTT broker.
Schema of the system:
Pictures of the system, I used ESP12E Devkit and some cheap parts:
References in Aliexpress where I bought the hardware:
Reading time: < 1 minute
In this video I describe deeply a convention called "Homie“; thanks to that we have a set of rules and assumptions very useful when a firmware device is created and/or an IoT platform have to be configured to support those devices. I love that convention and I used it during my demonstration scenario in Lviv IT Arena.
After this video I’ll follow a series of some other videos, describing how to develop devices following Homie conventions.
