Configuring Google Credentials

[alexbk66]

Note: from version 4.0.2.0 it's not required to create your own client ID / secret. So the following procedure is not necessary, unless you want to create your own credentials.

NOTE: New HS feature "Run as Service" prevents authorisation prompt. To configure Google credentials HS must run as normal process, not as service. Since Google use OAuth2 authentication protocol (which is not designed for console applications) this can be most difficult part depending on your OS and your setup. For initial credentials setup you have to use web browser on same computer where HS server is installed and logged in in your browser with your Google email. For Linux please see post Special first and this thread ! Go to Google Calendar device configuration:

Google changed the procedure, again. So I'll try to document the steps. It's a bit crazy, just follow the steps. 1. Go to https://console.cloud.google.com/cloud-resource-manager 2. Create New Project

3.Name the project (any name)

4. Select the created project Note: eaiser option for the following instructions is using project urls, I'll also list the urls - you need to append your project ID to the urls (i.e. project=gcal-3-320002)

5. Select "APIs and services" and Dashboard. Select "ENABLE APIS AND SERVICES" URL: https://console.cloud.google.com/api...=gcal-3-320002

6. Select "Google Calendar API" and Click ENABLE URL: https://console.cloud.google.com/api...=gcal-3-320002

7. Select "Create Credentials". Select Google Calendar API from the list, select "User Data", then "Next": URL: https://console.cloud.google.com/api...=gcal-3-320002

8. CONFIGURE CONSENT SCREEN - Enter App Name, Email (twice), Click "SAVE AND CONTINUE"

9. On SCOPES screen Click "ADD OR REMOVE SCOPES" Select "calendar.readonly" and "calendar.events", click "UPDATE", Click "SAVE AND CONTINUE"

10. "OAuth Client ID" Application type: Desktop App, Click "Create" and "Done"

11. "OAuth consent screen" URL: https://console.cloud.google.com/api...=gcal-3-320002 Test users => ADD USERS Add your gmail address again

12. Select 'pencil' to see the client ID and Secret URL: https://console.cloud.google.com/api...=gcal-3-320002

13. Copy"Client ID" and "Client Secret" to your Google Calendar Credentials configuration and click "Save" Google should pop-up OAuth authorisation window, follow the prompts. When finished - the plugin should get the list of you calendarts and create HS devices - 5 event devices per calendar.

Using authenticator.exe for headless HS install

If the HS is installed on headless (no GUI) Linux computer - the last reserve is to use authenticator.exe on another computer which does have GUI (better Windows) to obtain authorization token from Google. The app is included in the plugin install in "HS root"/bin/AKGoogleCalendar - copy the whole folder to Windows computer.

Note 1: Before using authenticator.exe you still have to obtain (and save/Submit on the config page) ClientID and ClientSecret from Google - follow instructions post #2 Configuring Google Credentials.

Note 2: On Linux even if you execute a command from the directory where it's located - you still need to prepend path, i.e:

./authenticator.exe

Note 3: And make sure on Linux it has the executable bit set, i.e:

sudo chmod a+x authenticator.exe

Now execute:

authenticator.exe ClientID ClientSecret

It should request "User login & consent" and receive "Authorisation code" and on success print list of your calendars:

*********************************************

omeseer #fbe983 95dfa41185hao6gmvpss2nelro@group.calendar.google.com HS-TV #ffad46

All you need to do now - in Google Calendar Credentials configuration click "Upload Credentials" and point to the file received above. This should copy the file to the plugin bin folder on HS machine.

Alternatively you can copy created token.json folder manually to: "HS root"/Bin/AKGoogleCalendar/token.json"

Then restart plugin.

Ver 4.0.0.22 (BETA) - Updated Google API to ver 1.55.0

Please enable "Show Beta Plugins" in Plugins => Add to see the BETA version.

I updated Google libraries, hope it helps.

I see you have only 4GB RAM which may be a problem (if not now, then later) - I suggest to upgrade to 8GB.

[austinbl]

It worked and I do plan to upgrade RAM to max 16GB ....

Thank You

[alexbk66]

No problem
