weewx-uradmon

Description

This extension provides a Service, and a Report skin that integrates with weewx (weather station software).

The Service captures and stores the output from an A3 uradmonitor into a local database at the exisiting archive interval (as set in weewx.conf) The Report will generate a seperate html page at weewx/uradmon/index.html with daily, weekly, monthly and yearly graphs as is done with the main weewx/ pages and your weather station.

Instructions:

1. Download the skin to your weewx machine.

   wget -O weewx-uradmon.zip https://github.com/glennmckechnie/weewx-uradmon/archive/master.zip

2. Change to that directory and run the wee_extension installer

   sudo wee_extension --install weewx-uradmon.zip

3. Edit the main weewx.conf file and under the [Uradmon] section add the IP address of your unit.

    # Options for extension 'uradmon'
    [UradMon]
        #urad_debug = True
        data_binding = uradmon_binding
        uradmon_address = 192.168.0.235
   

   It will appear as above. Change the 192.168.0.235 to point to your unit, using its IP or Qualified name.

   Next, edit the uradmon/skin.conf and in the top setion there is the unit_id that needs changing. Replace what's there with yours.

   [Uradmonitor]
           # id of your uradmonitor device, aka unit.
           # This is the unique nuber allocated by the uradmonitor site and
           # can be found on your dashboard page, once you are logged in.
           unit_id = 82000079
   

4. Restart weewx

   sudo /etc/init.d/weewx stop
   
   sudo /etc/init.d/weewx start
   

5. Problems? Hopefully none but if there are then look at your logs - syslog and apache2/error.log. If you view them in a terminal window then you will see what's happening, as it occurs.

   (I find multitail -f /var/log/syslog /var/log/apache2/error.log works for me {adjust to suit your install} -- apt-get install multi-tail if needed)

6.To uninstall

sudo wee_extension --uninstall uradmon

and then restart weewx

   sudo /etc/init.d/weewx stop

   sudo /etc/init.d/weewx start
   

Database options

In its default configuration, this skin will write to an sqlite database.

To change that to a mysql database then you need a suitable database user and to make a minor alteration to the uradmon entry in weewx.conf.

For the database, the following example assumes it will be named uradmon, and that the database user will be the weewx default user. eg:- The following extract shows your user...

[DatabaseTypes]
    [...]
    [[MySQL]]
        [...]
        user = weewx

That user can now be assigned the appropriate permissions to operate the needed database. You may need to create the user depending how you have previously setup weewx setup (the default is sqlite only, ie:- no mysql).

mysql -uroot -p
Enter password:

 [...]
 MariaDB [(none)]>CREATE USER 'weewx'@'localhost' IDENTIFIED BY 'weewx';
 MariaDB [(none)]> GRANT select, update, create, delete, insert ON uradmon.* to weewx@localhost;
Query OK, 0 rows affected (0.01 sec)

MariaDB [(none)]> quit;
Bye

With the above step done you'll then need to change one of the uradmon entries that was installed by the uradmon extension into weewx.conf...

Replace the old entry database = uradmon_sqlite with your new one database = uradmon_mysql eg:-

[DataBindings]
    [[uradmon_binding]]
        [...]
        database = uradmon_mysql

Save weewx.conf and then restart weewx as per the installation instructions above, then watch your logs for any errors. It should work seemlessly, but it always pays to check!
