[Thorben Thuermer]

Hello,

so you want to use the middleware/frontend to store/visualize your data,
but can't use vzlogger to import it.
(the prefered fix would ofcourse be to fix vzlogger to work with your
 meter! maybe if you give us the details of how you made it work,
 i.e. which timings are critical etc., we can fix hat for you...)

but there are two alternatives:
- send the data to the middleware API from your script.
  the api is quite simple, and documented:
  http://wiki.volkszaehler.org/development/api/reference
  (in german, if that's a problem, please complain!)
  basically all you need is:
  http://.../middleware.php/data/<uuid>.json?operation=add&value=<value>

- insert the data directly into the middleware's database,
  no need to put it into an intermediate database first.
  the format is relativey simple, just look at the database
  after installing the middleware (and maybe loading the test data).

- T.
