Google Calendar Scheduler - No instructions in log file

Tags: #<Tag:0x00007f616dcb2f48> #<Tag:0x00007f616dcb2d68>

Hi!

I’m completely stuck with trying to get the gcal add-on to work. Searched a lot but can’t find anyone else with the same issue.

I’ve followed the instructions. Installed add-on. Google API Manager, Credentials, edited the gcal.conf and added ID, Secret and Calendar name into it. Further instructions are supposed to show up in the log file when the bundle is started but it doesn’t.

The thing is my logfile doesn’t say one word about gcal. Nothing, i need to turn on debug mode to see anything happen at all.

With debug this is what I see when I stop and start it:

2019-09-15 00:17:14.926 [DEBUG] [org.openhab.io.gcal] - BundleEvent STOPPING - org.openhab.io.gcal

If I could just get something looking like an error I would be glad but it’s like its doing absolutely nothing.

Any ideas?

Its been awhile since I went through the installation, I did have an issue with missing the URL in the log file…I think removing the addon and adding it back triggered it.

Another thought did you run a (date stamp is just an example one to grep for)

cat /var/log/openhab/openhab.log | grep 2019-09-14 | grep Google-Integration

This would at least verify if it triggered the action or not.

I’ve been removing and installing it a couple of times. I can see in the log that it is beeing uninstalled. I’ve checked that the bundle is removed and unable to start. When I install it again I can see that in the log as well. Nothing else though but the previosly posted log entries in DEBUG mode.

I’m thinking it might have something to do with Google TTS beeing installed as well. I have Google TTS installed and working but as soon as I install Google Calendar Scheduler, Google TTS stops working. Uninstalling Google Calendar makes Google TTS start working again.
Looks like the authorization credential thing that is set upp with Google TTS stops working when Gcal i being installed. Tried to do it the other way around, installing Gcal without having TTS installed but that didn’t work either.

Interesting does the Google TTS have the gcal_oauth2_token already in place on the system? I’m not familiar with the TTS setup.
Do you have the ability to spin up a VM and install OH with just the gcal binding/addon? As you only need the gcal_oauth2_token to be generated and then you could move it to your primary OH system; but I am unsure what this would do to the TTS service.

No, Google TTS is set up with something called Service Account Key, not Oauth. I’m not so sure that would work, shouldn’t I see something in the log about a missing token or something. Just something telling me that the binding is not correctly set up at the moment. Where is the token supposed to be located?

/var/lib/openhab2/gcal/

Typically a sudo is needed to list the directory. Another thought, can you remove the TTS add on and the gcal add on and just run the gcal add on to see if the log generates?

Yes I tried that as well but with the same result…

Do you have an option to install another OH install just to validate with just the google calendar binding?

Yes I think that will be the next step. To start from the beginning. Might take a while before I have time to do it but…

I just did. And I can confirm the issue Gcal will kill GoogleTTS as soon as Gcal is beeing installed.
Thats OH 2.5 Stable Release: Rasbian Buster on Rpi4

Did any of you file an issue on Github?
