 Yes, it's possible to access anything in the dictionary. For example, 
 the name of the database used by the binding wx_binding would be given by

 config_dict['Databases']['wx_binding']['database']


 However, it is rarely necessary to do this. Better to use the functions 
 in manager.py to simply open up the database you need. For example,

 db = manager.open_manager_with_config(config_dict, 'wx_binding')


 would return a database Manager object for the wx_binding.

 See the section *Programming interface 
 * in 
 the Customizing Guide.

 For the first question, sorry, I wanted to say that if it possible to 
 pass argument that is not in stanza [myWlink] for example. Because I've 
 set 
 the same parameter for sql database if you know what i mean.

Re: [weewx-development] Weatherlink Live driver developpment

[Tom Keffer]

A driver is different from a service. The documentation you quoted is for a
*service*. You want the section *Porting to new hardware
*.

Take a look at Vince's driver that you linked to in the first post of this
thread. On line 106
,
the configuration dictionary (argument config_dict) is passed into the
function loader(). It contains everything in weewx.conf. On the next line,
107, just the substructure config_dict['WeatherLinkLiveJSON'], which
corresponds to the section [WeatherLinkLiveJSON]in weewx.conf, is passed on
to the class WeatherLinkLiveJSONDriver. Nothing else. That's a typical
pattern.

 Make sure you read the section *Porting to new hardware
 * in the
 Customizing Guide. It answers some of your questions.

 1. The full configuration information is available as the first
 argument to your driver loader() function as a dictionary. However, in
 general, you should try to keep your driver as modular as possible, and not
 pick and choose information from all over the dictionary. Best practice is
 to have your driver depend on information in its private stanza. For
 example, if your driver is named mywlnk.py, it should have a stanza

 [MyWlink]

 and look there for all its information. But, there are many exceptions
 to this best practice.

 2. The function genArchiveRecords() is a *generator function*. If you
 don't know what that is, see the section *Generators
 * in the Python
 documentation. It takes one argument: a timestamp with the last time in the
 database. Your function should return all archive records since that time,
 using a yield statement. It will be called at startup and at the end of
 each archive interval. However, exactly when should not be your concern ---
 that's the engine's job.

Re: [weewx-development] Weatherlink Live driver developpment

[Florentin Prevost]

Hi,

Thank you. I stuck just into passed config_dict.

How can I pass this value into my driver ? 

In documentation, he say that create class like this : 

class MyAlarm(StdService):
"""Service that sends email if an arbitrary expression evaluates true"""

def __init__(self, engine, config_dict):



Thank's

 Hi,

 I worked with the fork of 
 https://github.com/vinceskahan/weewx-weatherlinklive-json and I would 
 like to ask some questions about driver developpment. 

 - How can I passed argument of weewx.conf to my driver ? I work to 
 request lost data from Weewx on Weatherlink.com because WeatherLink Live 
 don't have API to take archive directly and I would like to passed some 
 arguments like archive_interval, sql password & etc 
 - How work genArchiveRecords when it call? It run as each report ? Or 
 it is a loop that waiting to have return values ?
