BakSeeDaa´s Google Calendar for Domoticz (deprecated)

[Ferpando]

Hello all,
I'm new to domoticz, but I come from a Vera environment.
I installed domoticz a few days ago on my Synology, and today I tried to install the gcal plugin.
I followed all the steps but I get this error in the log:

2015-10-23 09:43:51.472 Error: EventSystem: /usr/local/domoticz/var/scripts/lua/script_device_gcal.lua:34: module 'scripts/lua/gcalconfig' not found:
no field package.preload['scripts/lua/gcalconfig']
no file '/usr/local/share/lua/5.2/scripts/lua/gcalconfig.lua'
no file '/usr/local/share/lua/5.2/scripts/lua/gcalconfig/init.lua'
no file '/usr/local/lib/lua/5.2/scripts/lua/gcalconfig.lua'
no file '/usr/local/lib/lua/5.2/scripts/lua/gcalconfig/init.lua'
no file './scripts/lua/gcalconfig.lua'
no file '/usr/local/lib/lua/5.2/scripts/lua/gcalconfig.so'
no file '/usr/local/lib/lua/5.2/loadall.so'
no file './scripts/lua/gcalconfig.so'

I don't know if this is caused by the fact it is on a synology, because the path LUA scripts are stored is:

/usr/local/domoticz/var/scripts/lua

All the files are in the LUA folder.
Anyone else having this problem?

[BakSeeDaa]

Hi there @Ferpando

I see that your scripts directory is ./var/scripts/lua/ (relative from Your domoticz directory). On a Raspberry environment it is simply ./scripts/lua/

Due to the fact that I've assumed that the lua scripts directory is always ./scripts/lua/ (relative from current directory) the config file and the other help scripts involved cannot be found.

I will have a look into that and see if I can fix it.

Meanwhile... It might work if you create a symbolic link named scripts in your Domoticz directory pointing on your scripts directory. (Assuming there is not already a directory named /usr/local/domoticz/scripts)

Code: Select all

sudo ln -s /usr/local/domoticz/var/scripts /usr/local/domoticz/scripts

Please report back if it works. Thanks.

[Ferpando]

Thank you for the fast response.
I'll try your suggestion to see if it helps.
Here is the main folder structure on my synology, in case it helps you.

folder.gif (4.11 KiB) Viewed 3649 times

folder1.gif (3.72 KiB) Viewed 3649 times

[BakSeeDaa]

...I'll try your suggestion to see if it helps.

Is it working now?

[Ferpando]

I'm afraid not.

First I don't have sudo in my synology, so the way I made the symbolic link:

mount -o bind /usr/local/domoticz/var/scripts /usr/local/domoticz/scripts

But I still get the same errors... I don't have any folder named 5.2

Can I see the symbolic link?

Please enter the following command to list

I deleted the calendar files to prevent flood of log file, but they were there before

[BakSeeDaa]

Hmmmm...

Attached is a zip file. Please unzip it and put the unzipped file into your lua scripts folder.
Click a button or something and look into your log for some output like:

Code: Select all

2015-10-23 18:03:24.253 LUA: pwd result is: /home/pi/domoticz

Please report the result here. It would help a lot to know.

Then delete the file

[BakSeeDaa]

@Ferpando... I will be back again tomorrow to see what I can do about it.

[Ferpando]

That explains it. Now I know what's going on ... I'll get back to you tomorrow then.

[BakSeeDaa]

Good morning @Ferpando

You can remove the symbolic link that you created before. Just be careful not to remove your original scripts folder when doing that. I'm not familiar with the Synology environment but it might be enough to reboot your system for the symbolic link to disappear.

In the Raspberry Pi environment the "working directory" for the Domoticz process is /home/pi/domoticz
In your case, in Synology the "working directory" is /root and the lua scripts folder is
/usr/local/domoticz/var/scripts/lua which is also different.

I believe we can get a step further if you create a symbolic link named /root/scripts pointing to /usr/local/domoticz/var/scripts

After doing that

If you do ls -la /root/scripts/lua/ you should be able to see your Lua scripts there.

Would You like to try that @Ferpando?

[Ferpando]

ok, we went a step away... but not quite there yet

Now the errors are different. Domoticz is on port 8084 on the synology.
No user variables were created.

[BakSeeDaa]

OK, thanks.

Please try the following:

1) Add a user variable named GCalHostAndPort of the type string and enter localhost:8084 as the value.
2) Attached is a new zip file. Unzip it and put the extracted file in the lua scripts folder. (Replacing the old file with same name).

Then please try again. I believe we are getting closer now

[Ferpando]

ok, we are progressing in the right direction

now, where should i put the gcal.json file? in /root?
A folder GCal3 was created there...

also openssl.cnf is located at

/usr/local/domoticz

[BakSeeDaa]

Normally the credentials file named GCal3.json shall be put in /home/pi/domoticz/GCal3/ In Your case on Synology, put your GCal3.json in /root/GCal3/
Keep that folder, don't delete it later.

Before BGCD did a check that openssl is installed on the system. I've removed that check because the command to check differs depending on what system Domoticz is running on.

1) Check that you have openssl installed on your system. If not, install it.
2) Attached is a new zip file. Unzip it and put the extracted file in the lua scripts folder. (Replacing the old file with same name).

Please try again.
