Now, navigate to the folder containing the hotword.py script. Since this is a virtual environment, you'll need to install RPi.GPIO before moving forward. You will need to replace my-dev-project with your Project ID . Your device-model-id is listed under the Device registration section of the Action Console.
Then enter the same parameter name in the actions section. Voice controlled assistants have quickly become commonplace. Many homes have an Alexa or Google Home controlling everything from lighting to media, and even timekeeping. Sudo service mini-httpd restart Now you have a web server. Put the Pi IP address into a Raspberry Pi to test it. The phrases can contain parameters to be sent to the Pi too.
Get the Medium app
You have your server running, and it can control a relay. It is structured so that a POST request can change the state of the relay. Now all you need is to get your Google Home to deliver a POST request to your device. Eventually, you will want to add some authorization so that strangers can't control your devices, but now we just want the request to work.
You will get a successful pair message but the speaker is not connected yet. Go to the speaker icon on the top menu bar. Your speaker should produce a chime or voice notification to indicate the Bluetooth connection is successfully made. If you don't want to use the monitor, keyboard, and mouse at next startup, enabling these options would allow you to remote access the Pi.
Step 2: Prepare SD Card With the Latest Raspbian OS (Stretch)
The technology these devices run on is available---at least in part---to everyone. Google's Assistant SDK allows you to use the service on your own devices. This tutorial covers how to set up the Google Assistant on your Raspberry Pi, and voice activate an LED via GPIO pins. If it didn’t work, clues may be lurking in the ifttt activity log or the Pi /var/log/mini-httpd.log file. You can also try adding lines to the script to log something to a file somewhere.
It just happens that ifttt provides a fairly simple way to combine the two and end up with voice controlled Christmas lights. The next step is to create a CGI program to be run when a URL is requested. I called my script “switch” as I want to use it to control my Christmas lights. On my main site there’s some information about using a Pi to control electrical sockets without risking killing yourself.
Install Google Assistant SDK
To feel the real "Google Home" we will be adding custom sounds and led light response. Click on Select Drive and find the drive of your micro sd card reader.
I suspect that most buttons that support Alexa would be good candidates, or you could find a way to do it directly through the Pi. First things first - I'd recommend trying to download the server first and run it on your computer. It can be harder to experiment and iterate directly on the pi, and this seems to be your first experience with a server.
Go to the Bluetooth icon on the top menu bar, turn on Bluetooth and then add a Bluetooth device. You need to install your Pi Zero W on the Raspberry Pi Zero Docking Hub. There are 4 sets of screws and standoffs and it will take less than a minute to assemble. Once the image is prepared, eject the card safely and get ready for next step. Controlling their fireplace, so I thought I'd show you my own approach.
I already use dyndns for other things so was covered there. This step is important to get the Raspberry Pi Zero Docking Hub audio to work with the Google Assistant software. Left mouse click over the WiFi icon on the top bar. You only need to do once unless the network setting has changed or need to be changed.
If you have USB 2.0 microphone then steps followed are same to check the microphone. Here we have used Webcam for USB microcphone. I got the server to say that its listening to port xxxx but when I try to use it in the browser it says connection refused. So, there are lots of guides on getting started with relays on the Rasberry Pi. I mostly used Youtube tutorials like this one to get started.
To get this credentials file click the Download OAuth 2.0 credentials. This file is very important so, keep it somewhere safe. Now after you boot up your raspberry pi you may now go this Github Repository of GassistPi and you may also follow the guide there. Plug the raspberry pi to your monitor with the hdmi cable. There are plenty of ways you could make that work! I wanted mine to use a website or use voice control, but you could definitely find some way to get a button to trigger IFTTT.
First, connect to the raspberry pi Get the latest nodejs run-time from the following command in the terminal. I guess this has been two guides really. CGI scripts on a Pi and Google Home interfacing.
So this is how we can install Google Assistant on Raspberry Pi and can turn it into a Google Home by connecting a Speaker and microphone to it. Whenever you want to launch Google assistant, just get in the environment and follow the below steps. Run the following command to install Python3 and the Python 3 Virtual Environment to our RPi. Here you have to activate the following activity controls to ensure that the Google Assistant API work fine. After logging in to your Google account, you will see following window. This GassistPi project can also helps you to automate your house.
You’ll also need to route web traffic from a fixed URL to your Pi. This can be on a non-standard port but don’t assume that’s any form of security. It’s probably best to avoid anything on there that could be useful to the bad guys or expensive to you. If your ISP doesn’t give you a static IP address, you may need to use a Dynamic DNS provider.
