Smart Home Project 2
Control TV (and other IR devices) with voice commands, using Amazon echo.
The difficulties of the project:
Build the electrical circuit was challenging we got professional help from electronic engineer.
The electrical circuit building was challenging and we used some support of electrical engineer to deal with it.
Programming in Amazon workspace.
Integrate many tools and make them work together (combining code and libraries from many different sources).
What we achieved:
Improvement of RPI Amazon Echo from here: smart-home-project so it can run now using only one command.
We control TV and other IR devices.
Catch IR codes and translate them to 1 line IR code.
We add for Amazon echo skill from the link above the ability to send HTTP requests.
The needed equipment:
ESP8266 NodeMcu board
Super bright IR led
Here you can find all the details about the circuit In the link: https://github.com/mdhiggins/ESP8266-HTTP-IR-Blaster
Go to Amazon developer and create a new skill:
Copy the intent schema
Copy the sample utterance
In “aws” create lambda function:
Copy the code and save
Editing the given code:
adding your own command
In the skill:
Make a new intent in the intent schema
Add sample utterances
In the lambda function:
Change the IP in the top of the code to your global IP (it is recommended to use dynamic DNS service).
Add IR block and enter the -1 line IR code, the intent name and the other parameters of the block.
Proposal for future projects:
Expand the skill to Control devices with web API using the HTTP requests.
