Hi,

I wrote a daemon using your library for a Kaifa meter. Now I want to use the same for a Politerm 800, but of course the format is different. I keep getting this error:
Exception: Error in path (parsing) -> meter_ts_item -> item_type

Do you know of good debugging tools to figure out the format so I can modify your code to work with the Politerm?

Thanks!

Hi,

Tried using this library on my Kaifa MA304H4, using a Rapsberry PI and this USB dongle:

This is the error message I get.

It works fine with the C-library from Per Erik Norbø. I was hoping to use your python library to pipe the data to MQTT. I would be happy to be a tester for this meter/dongle combo for your library, just instruct me on what to do.

Hi, testing out your package and got the following. Any ideas wha would cause it?
