@ -171,6 +171,8 @@ Parsing module usage
The parsing module accepts complete unaltered telegram strings and parses these
into a Telegram object. This previously was a dictionary, but the Telegram object is mostly compatible.
Getting full telegrams from a bytestream can be made easier by using the TelegramBuffer helper class.

Telegram object
---------------------
A Telegram has attributes for all the parsed values according to the given telegram specification. Each value is a DsmrObject which have a 'value' and 'unit' property. MBusObject's, which are DsmrObject's as well additionally have a 'datetime' property. The 'value' can contain any python type (int, str, Decimal) depending on the field. The 'unit' contains 'kW', 'A', 'kWh' or 'm3'.
Below are some examples on how to get the meter data. Alternatively check out the following unit test for a complete example: TelegramParserV5Test.test_parse
