ESP8266-WemosRelay

Simple project for making an Amazon Echo/Alexa compatible IoT device with a Wemos D1 + Relay Shied.

Features

Amazon Echo/Alexa Support (fauxmoESP)
Easy Wifi Configuration (ESPAsyncWifiManager)
Async Web Server support (ESPAsyncWebServer)
Built-in Configuration Web site
AngularJS site with REST based API
Static site is stored in SPIFFS, utilizes CDNs to reduce footprint
ArduinoOTA to support OTA updates plus loading SPIFFS
Built using PlatformIO

3rd Party Libraries

This project is designed to serve as a starter project for controlling a Wemos D1 + Relay Shield. Out of the box it is configured with the following libraries

ESPAsyncWifiManager
- Provides an simple WiFi setup process for configuring a new device and assigning a name for within Alexa.
fauxmoESP
- To add simple support discovery plus On/Off commands from Alexa and other IoT platforms
ESPAsyncTCP & ESPAsyncWebServer
- Add support for a light-weight web server
AruidnoJSON
Utilized for Configuration storage plus REST based API

SPIFFS

The application does utilize SPIFFS for storing configuration as well as the static files for the web site.

Configuration is stored within /config.json
Web application file system
- index.html
- main.js

Don't forget to load SPIFFS into the device. pio run -t uploadfs

Web Server

Supported URLs

Static site (from SPIFFS)
- index.html
- main.js
/relayon
/relayoff
/reset
- Triggers a CPU reset
/resetwifi
- Reset Wifi Configuration (which will trigger setup Hotspot upon restarting)
/heap
- Return available HEAP Used for the AngularJS site
/info
