ESP8266 Gardener

An ESP8266 based project for remotely watering plants on battery power.

Compiling the ESP8266 Gardener

The ESP8266 Gardener connects to your Wi-Fi network and communicates with AWS IoT in the cloud. As a prerequisite, you will need to have an AWS account.

First, create a file in the root folder named keys.cpp. This file will contain your passwords and other details that are unique to your project.

Next, use the included AWS CloudFormation template to create a new stack. Once the CloudFormation stack is created, look at the outputs from the stack. You should see AccessKeyID, SecretAccessKey, AWSRegion, and AWSPath.

In the keys.cpp file you created, add the following:

#include "keys.h"

const char* awsRegion = // The CloudFormation output value for AWSRegion;
const char* awsDomain = // Get this from https://console.aws.amazon.com/iot/home, Manage, Thing, Interact, Rest API Endpoint. or from https://docs.aws.amazon.com/iot/latest/developerguide/thing-shadow-rest-api.html;
const char* awsPath = // The CloudFormation output value for AWSPath;

const char* awsKeyID = // The CloudFormation output value for AWSKeyID;
const char* awsSecKey = // The CloudFormation output value for SecretAccessKey;
const char* ssid = // The SSID for your wi-fi network;
const char* password = // The password for your wifi network;

The ESP8266 Gardener uses the Arduino core for ESP8266 library. To compile and install it on your ESP8266 device, open esp8266-gardener.ino in the Arduino IDE.
