Connect LEDs with colours of your choice to GPIO05 for Listening and GPIO06 for Speaking Events.
Connect a pushbutton between GPIO23 and Ground. Using this pushbutton, now you can stop the music or radio playback.
The default GPIO and shutdown trigger word is trigger. It should be used for controlling the GPIOs, servo and for safe shutdown of Pi.
It has been intentionally included to prevent control actions due to false positive commands. If you wish to change the trigger word, you can replace the 'trigger'in the main.py code with your desired trigger word.
The default keyword for servo motor is servo. For example, the command trigger servo 90 will rotate the servo by 90 degrees.
If you wish to change the keyword, you can replace the 'servo' in the action.py script with your desired keyword for the motor.
For safe shutdown of the pi, command is: trigger shutdown
You can define your own custom actions in the actions.py script.
THE ACTIONS SCRIPT OF THIS PROJECT IS DIFFERENT FROM AIY KIT's SCRIPT, COPY PASTING THE COMMANDS FROM AIY's ACTION SCRIPT WILL NOT WORK HERE. FOR A BETTER UNDERSTANDING OF THE ACTIONS FILE, FOLLOW THE FOLLOWING YOUTUBE VIDEO.
There are two ways to control NodeMCU:
- Control of NodeMCU running a webserver.
- Control of NodeMCU running Sonoff-Tasmota Firmware.
Download the Arduino IDE code for Nodemcu from here: https://github.com/shivasiddharth/iotwemos/blob/master/Google-Home-NodeMCU.ino
Add the wifi credentials, make the desired changes and upload the Arduino code onto the NodeMCU and get the IP address from the serial monitor.
Add the NodeMCU's IP address in the actions.py file.
Syntax: "Hey Google, Trigger Turn Devicename On/Off"
FOR GUIDELINES ON MODIFYING THE ARDUINO CODE AND ACTIONS.PY FILE, FOLLOW THE FOLLOWING YOUTUBE VIDEO.
Download the Tasmota firmware from this link
Follow the instructions in this video to upload the firmware properly.
Pi3 and Pi Zero users, assign the device names and device ip addresses in the main.py script and pushbutton.py script respectively, in the marked locations.
Syntax: "Hey Google, Turn Devicename On/Off"
Advantage of using Sonoff-Tasmota over webserver is that, with Sonoff-Tasmota you can emulate a Wemo switch and control the NodeMCU using Amazon Alexa (Echo Devices) in addition to the GassistPi.
Default command for casting YouTube videos is Play Desired Video on Chromecast, with Chromecast as the trigger word. Example: Hey Google, Play MasterChef Season 1 Episode 1 on Chromecast casts the MasterChef YouTube Video.
Note: YouTube casting to Chromecast using third party scripts has been blocked, so I have taken a roundabout approach and as a result, you may not find the usual YouTube interface on Chromecast.
First, add the IP-Address of your Chromecast in the actions.py script, in the indicated location.
Following are the default commands for controlling Chromecast with Chromecast as the trigger word.
Pausing:
Hey Google, Pause Chromecast
Resuming:
Hey Google, Resume Chromecast
Stopping: Hey Google, End Chromecast
Change volume up/down:
Hey Google, Chromecast Volume Up/Down
You can change volume and pause or resume the Radio/YouTube/Google Music by voice.
Pausing:
Hey Google, Pause Music (Entire phrase Pause Music is the trigger)
Resuming:
Hey Google, Resume Music (Entire phrase Resume Music is the trigger)
Volume Control (Music Volume is the trigger)
Increase/Decrease Volume:
Hey Google, Increase/(Decrease or Reduce) Music Volume by ( a number between 0 and 100)
If you do not specify a number, by default the volume will be increased or decreased by 10 units.
Set Volume:
Hey Google, Set/change Music Volume to ( a number between 0 and 100)
Set volume to Maximum/Minimum:
Hey Google, Set/change Music Volume to maximum/minimum
The updated music streaming features autoplaying of YouTube suggestions. This makes use of the YouTube Data API v3.
- Go to the projects page on your Google Cloud Console-> https://console.cloud.google.com/project
- Select your project from the list.
- On the left top corner, click on the hamburger icon or three horizontal stacked lines.
- Move your mouse pointer over "API and services" and choose "credentials".
- Click on create credentials and select API Key and choose close. Make a note of the created API Key and enter it in the actions.py script at the indicated location.
- "From the API and services" option, select library and in the search bar type youtube, select "YouTube Data API v3" API and click on "ENABLE".
- In the API window, click on "All API Credentials" and in the drop down, make sure to have a tick (check mark) against the API Key that you just generated.
Note: The same API key can be used for Kickstarter Tracking, but Custom Search API must be added to the project in the cloud console.
Music streaming has been enabled for both OK-Google and Custom hotwords/wakewords.
Default keyword for playing music from YouTube without autoplay is Stream. For example, Stream I got you command will fetch Bebe Rexha's I Got You from YouTube.
Default keyword for playing music from YouTube with autoplay is Autoplay and Stream. For example, Autoplay and Stream I got you command will play the requested I Got You and after the end of the track will autoplay susequent tracks. The number of autoplay tracks has been limited to a maximum of 10. this can be changed the under the YouTube_Autoplay function in the actions.py script.
Due to the Pi Zero's limitations, users are advised to not use the Music streaming feature. Music streaming will send the CPU usage of Pi Zero into the orbit.
The music streaming from Google Music uses Gmusicapi.
Enter your Google userid and password in the actions.py file in the line "logged_in = api.login('YOUR_GMAIL_ID', 'YOUR_GMAIL_PASSWORD', Mobileclient.FROM_MAC_ADDRESS)". If you are using a two-step authentication or two-factor authentication, generate and use an app specific password.
Refer to this page on google help - https://support.google.com/accounts/answer/185833?hl=en
Play all your songs in loop using the syntax: "Hey Google, Play all the songs from Google Music"
Play songs added to the user created playlist (does not include: most played playlist, thumsup playlist, etc) using the syntax: "Hey Google, Play songs from the first playlist in Google Music" Playlists are sorted by date created, if you have multiple playlists, use a similar syntax replacing first with second, third etc. Also you need to make suitable changes in the main.py (It has been commented in the script to help)
Play songs by a particular artist using the syntax: "Hey Google, Play songs by artist YOUR_ARTIST_NAME from Google Music"
Play songs from particular album using the syntax: "Hey Google, Play songs from album YOUR_ALBUM_NAME from Google Music"
Change tracks Shuffle tracks Repeat tracks
Due to the Pi Zero's limitations, and computationally intensive nature of the Google Music streaming feature, this action has not been enabled for Pi Zero.
Default keyword for streaming radio is radio. For example, play Radio 2 or play Radio One command will open the corresponding radio stream listed in the actions.py file.
Radio streaming has been enabled for both OK-Google and Custom hotwords/wakewords.
Useful links for obtaining radio streaming links:
http://www.radiosure.com/stations/
http://www.live-radio.net/worldwide.shtml
Due to the Pi Zero's limitations, users are advised to not use the Radio streaming feature. Radio streaming will send the CPU usage of Pi Zero into next galaxy.
The default keyword for tracking parcel is parcel. For example, you can say where is my parcel or track my parcel.
Regsiter for a free account with Aftership at https://www.aftership.com gnereate an API number and add parcels to the tracking list. The generated API number should be added to the actions.py script at the indicated location. For a better understanding follow the attached youtube video.
Default keywords for playing RSS feeds is feed or news or quote. Example usage, top tech news will play the top technology news, top world news will play top news related to different countires, top sports news will play the top sports related news and quote of the day will give some quotes.
Do not mix the commands with Play as that has been associated with music streaming from YouTube.
numfeeds variable within the feed function in actions.py file is the feed limit. Certain RSS feeds can have upto 60 items and numfeeds variable limits the number of items to stream. The default value has been set to 10, which if you want can change.
The Kodi integration uses YouTube Data API v3 for getting video links. First step is to add the API to the project and create an API KEY.
- Go to the projects page on your Google Cloud Console-> https://console.cloud.google.com/project
- Select your project from the list.
- On the left top corner, click on the hamburger icon or three horizontal stacked lines.
- Move your mouse pointer over "API and services" and choose "credentials".
