I you update to latest beta by running ./updatebeta in the domoticz directory, the plugin directory should be created. And there will be a few examples included as well. At least that happened to me when I made a fresh install on a new Rasp.

I'm trying to use Python requests library to make HTTP calls. I have the latest Domoticz Beta version 3.7266, but with previous versions I have the same problem.

I faced with really strange behavior:
1. When I'm trying to import request module in the file head, plugin stops working immediately, even onStart is not called

Code: Select all

import Domoticz

import sys
sys.path.append(sys.prefix+'/lib/site-packages')

import requests;

def onStart():
    Domoticz.Log('Start')
    return True
2. When I'm trying to import request module in onHeartbeat function then this function will be called ones, return result to Domoticz (log message in example) and plugin stops working

Maybe someone know what's happening or faced with the same problem?
Sample plugin code is in attachment.

I had the same issue with the requests module and my Sony Bravia python scripts.
I changed to urllib module and then it's working fine.

See https://www.domoticz.com/forum/viewtopi ... 10#p126606.

Thank you for solution.
Maybe someone know the root cause of problem or the way how I can debug it.

I have seen a similar problem importing a GPIO library. The complete plugin system halts. No callback function is called. Just a import reference is enough to result in this error.

One thing to consider is that a 'Just a import reference' means that Python will load and execute the library.

Some libaries will just not be happy with the restriction that Domoticz does not enable Python threading and will not be usable.

@Dnpwwo,

I can understand, that not everything is possible within the Domoticz 'restricted' python environment. However I do think there is something strange going on. I've seen that calling a library function lock's up Domoticz depending on when it's called. In addition if a plugins throws an exception, Domoticz tends to completely lockup.
It would be nice if Domoticz would be protected against 'faulty' plugins. There could be coding errors resulting in throwing exceptions within the plugin, errors within standard libraries used or Domoticz restrictions that are not handled correctly within a library etc. All of these now tend to lockup the complete Domoticz system instead of just crashing/stopping the plugin it concerns.
The plugin system is a great new feature, and definitely gives Domoticz an edge over other systems, but in its current state (still beta of course) I think it compromises the stability of the Domoticz system and some steps should be made there.

Kind regards,

Jorg

[UPDATE] It seems it is working in fact even if there no message in the log. I can find the new element in the material list
Please apologize for my coming question but in the Kodi plugin there are a lot of reference to image number, swichType number, subtype... where could I found the reference for all those elements?
I went through the wiki but I have not been able to find it.

Thanks for your help.



I have tried to play with python plugin... but can't make it working. I am using the Kodi plugin that I put in a dedicated directory.

@Mat2Vence,

The plugin system is starting and if 'plugin.py' is in '/home/mthomas/domoticz/plugins/<any folder name>' then it will be found. There are no messages from plugins unless you create an entry on the hardware page that uses one.

Go to the hardware page and add the Kodi selecting 'Kodi Players' from the 'Type' drop down. After that you should see entries in the log as it starts.

@Dnpwwo,
Thanks. You are right. It's working.
Did you know where to find all these reference of type, subtype, image ID that are used in Python plugin?

@Mat2Vence,

That stuff is not really documented all in one place, its in the Domoticz code itself.

If possible I would recommend using the TypeName parameter (see http://www.domoticz.com/wiki/Developing ... in#Devices) which will give you a working Type, SubType and ImageID combination.

If you know of device that has what you want you can create one then look in the DeviceStatus table in the database to find the Type & SubType.

What are you trying to create?

I'm trying to develop a python plugin using google maps package. But at very basic level, when I just import the Google maps package, onStart is not being called anymore. If I drop the googlemaps import it is working again.

I don't get any errors however in the Domoticz log. What could be the problem?

So the output in the log in case of importing the package is just (nothing more):
2017-05-13 12:13:14.757 (Test) Initialized version 1.0.0, author 'mastair'

While when I drop the import the output is like expected:
2017-05-13 12:13:14.757 (Test) Initialized version 1.0.0, author 'mastair'
2017-05-13 12:13:14.757 (Test) onStart called

@mastair,

That normally means that the library is trying to do asyncronous or thread stuff (which is not supported).

Thanks, got another question. Trying to create a custom sensor from Python, and I want to add the axis label / units.

In SQLite the options field of a similar device contains "1;minutes" without the quotes of course. I wouldn't know how to translate this to a python dictionary.

Anyone?

Edit: Figured it out, needed a newer version of Domoticz and provide this as dictionary: Options={"Custom": "1;minutes"}
