Home Automation with NodeMCU and Alexa using fauxmoESP

fauxmoESP is a library for ESP8266/ESP32-based devices that emulates Philips Hue lights and thus allows you to control them using this protocol, in particular from Alexa-powered devices like the Amazon Echo or the Dot.

The library can be found on Xose Perez's BitBucket: fauxmoESP

The below video, shows how the project will look like at the end:

Material

1. NodeMCU ESP8266-12E
2. Echo Dot (2nd Generation)
3. 2 X Mini BreadBoard
4. 4-Channel Relay Module
5. Male-Female Dupont Cables
6. External 5V power Supply

Dependencies

1. fauxmoESP Library ZIP In order to run it in your code, you will also need 2 more libraries by Hristo Gochkov:
2. ESPAsyncTCP
3. ESPAsyncWebServer

Step One:

Download or clone full source code from here: Source Code

So, Unzip the files and Go to your Arduino IDE and install the 3 above libraries from libraries folder under your Arduino/Library directory or Install by zip option.

Step Two:

Open the file NodeMCU_with_Alexa_Home_Automation.ino from my GitHub folder and change the dummy wifi credentials, with your own:

/* Network credentials */ #define WIFI_SSID "YOUR SSID HERE" #define WIFI_PASS "YOUR PASSWORD HERE"

Select your board and upload to NodeMCU board.

Step Four:

Diagram

Let's connect a 4 Channel relay module to control 2 lamps and 2 outlets as shown in above diagram. We will create 4 "single smart devices":

1. Light1 ==> Relay 1 ==> NodeMCU D5
2. Light2 ==> Relay 3 ==> NodeMCU D7
3. Outlet1 ==> Relay 2 ==> NodeMCU D6
4. Outlet2 ==> Relay 4 ==> NodeMCU D8

and 3 groups of combined devices:

All Devices (Light1, Light2, Outlet1 and Outlet2) Living Room (Light1 and Outlet1) Bed Room (Light2 and Outlet2)

Important Things

1. Setup Ardunio Preference for NodeMCU

2. Instal NodeMCU Board version 2.3.0 Its very important other wise Alexa dont discover devices

3. Select Your NodeMCU board with correct model
