QUESTION
I'm currently building out a Google Home project in NodeJs that has a fulfillment service that uses a downloaded service account key. This key is deployed with my fulfillment service to my firebase function.
I'd like to avoid storing the key in an environment variable and I would absolutely like to avoid other members of my team needing to downloading a new key for deployments.
I see with some google services you can use ADC to automatically get the service credentials but I can't seem to find a way to get the same information as the json file through the google-auth-library.
Is there a way to initialize the smarthome service from the actions-on-google-nodejs library from the service account assigned to the function?
ANSWER
Answered 2021-May-21 at 16:56For anyone looking for an answer to this, it's been a couple months and it seems Google has included requestSync and reportState into the googleapis npm package (that or I completely missed it before). This package no longer requires a service account key.
QUESTION
I try to build my custom IoT device that will be controlled via Google Home device, and serve people with disabilities.
The device itself is Tiva C Launchpad, that I program from scratch, meaning I will have a full control on it.
In my vision, the user wil say something like: "Ok Google, press play button", and as a result, the Google Home device will send a direct command of press_play_button to the IoT device, preferably via the local network.
I found the Google Action SDK, alongside with the Local SDK extention, but if I understood correctly, I have to be in the app mode first ("OK Google, play {app_name}") before pronouncing the action I want, which is inconvenient.
Is there any way to achieve my requirement? If not, I may give up on the local network control, and use sort of a webhook to send HTTP request to my smart device, and in that case I wonder if MQTT will be more suitable.
Thanks.
...ANSWER
Answered 2021-May-12 at 20:13The Local SDK is an extension to the Smart Home API. If your device matches up with the device types and traits that the Smart Home API supports then you can use that to control your device.
It has support for media players so things like play/stop should be possible.
I have build generic Smart Home control using MQTT to reach the device, but you have to provide a HTTP endpoint for the Google System to interface with. This take a little thought as you have to map MQTT asynchronous approach to HTTP's synchronous nature.
QUESTION
I need to handle errors in my API server on node.js. I created a error handling module, which sends the errors (only in dev mode) to the API client in a JSON object similar to this:
...ANSWER
Answered 2021-Mar-20 at 14:10Instead of throwing the error, perhaps want to throw it to next like this so it can be handled by the error handler.
QUESTION
I'm relatively new to GoLang, and am having trouble with the strict typing system (I'm much more used to weakly typed languages).
In trying to write a Alexa SmartHome skill I need to create the JSON structures defined (e.g) at https://developer.amazon.com/en-US/docs/alexa/device-apis/alexa-contactsensor.html
The StateReport Response is where I start to have trouble, in particular with the context.
The example looks like:

Answered 2021-Apr-19 at 03:14Using the hint from mkopriva I think I came up with simple proof of concept solution using interface{} and anonymous structures
QUESTION
Given the protocol buffers definition available at: https://github.com/googleapis/googleapis/blob/master/google/home/graph/v1/homegraph.proto
How can one call the Home Graph API RPC endpoint using gRPC on Node.js to multiplex concurrent API method calls over a single connection?
...ANSWER
Answered 2021-Apr-15 at 17:54You can use @grpc-js in combination with Application Default Credentials to initialize the credentials.
QUESTION
I'm using flask-sqlalchemy orm in my flask app which is about smarthome sensors and actors (for the sake of simplicity let's call them Nodes.
Now I want to store an Event which is bound to Nodes in order to check their state and other or same Nodes which should be set with a given value if the state of the first ones have reached a threshold.
Additionally the states could be checked or set from/for Groups or Scenes. So I have three diffrent foreignkeys to check and another three to set. All of them could be more than one per type and multiple types per Event.
Here is an example code with the db.Models and pseudocode what I expect to get stored in an Event:
ANSWER
Answered 2021-Apr-01 at 12:08I ended up with a trade-off between usage and lines of code. My first thought here was to save as much code as I can (DRY) and defining as less tables as possible.
As SQLAlchemy itself points out in one of their examples the "generic foreign key" is just supported because it was often requested, not because it is a good solution. With that less db functionallaty is used and instead the application has to take care about key constraints.
On the other hand they said, having more tables in your database does not affected db performance.
So I tried some approaches and find a good one that fits to my usecase. Instead of a "normal" intermediate table for many-to-many relationships I use another SQLAlchemy class which has two one-to-many relations on both sides to connect two tables.
QUESTION
Is there any list of sample utterances to the google smart home device types/traits? Since, google smarthome action device types/traits are pre-built, It's terrible not stating some sample utterances under each device type/trait in the google action developer documentation. Otherwise, developer has no clue what are supported utterances.
...ANSWER
Answered 2021-Mar-01 at 17:32I'm not sure if there's a specific issue you're seeing, as there are sample utterances in the trait documentation, Brightness for example has sample utterances under the Examples heading.

I'm sending a report state request in my onExecute handler. It fails with:
ANSWER
Answered 2021-Feb-22 at 17:40Though you can receive inbound requests, you are not immediately able to make outbound requests back to Google. First you must activate the HomeGraph API and download a service account key.
Then add that to your SmartHomeApp:
QUESTION
What's the flow when user choose to unlink account from developer's own app/website? I understand that developers should at least send a user-delete reqeust to homegraph api(as mentioned in https://developers.google.com/assistant/smarthome/reference/rest/v1/agentUsers/delete), but what else should developers do? Should we revoke the OAuth authorization from our own OAuth server? What's the complete process of account delete from server side?
...ANSWER
Answered 2020-Dec-04 at 16:29When the user unlinks their account, your webhook will receive a DISCONNECT intent.
