Scheme

Prerequisites:

• Arduino IDE
• Hardware: ESP8266 board, DS18B20 sensor

Build Setup

install additional board to Arduino IDE

Arduino board project Howto

Official Arduino IDE info on how to install additional cores

install additional libraries

go to Sketch -> Include Library -> Manage Libraries

type in “Search” and install:

• Adafruit_MQTT_Library MQTT library for ESP8266 with SSL support

• OneWire 1-wire temperature sensors, memory and other chips

select board

Arduino IDE: Tools -> Board -> Generic ESP8266 module

get FlespiToken

register on flespi platform, create a Token in a tokens Tab and paste token in .ino file definitions:

#define FLESPI_TOKEN "FlespiToken REPLACE_WITH_YOUR_FLESPI_TOKEN"

test

compile the project and flash the board

To test it works you can use flespi online MQTT client:

Paste yout token and subscribe to topic “/ESP8266/test”
