DSMR wont read under Home Assistant and gives always the same error.

Logger: dsmr_parser.clients.protocol Source: /usr/local/lib/python3.9/site-packages/dsmr_parser/clients/protocol.py:121 First occurred: 02:07:00 (1308 occurrences) Last logged: 12:34:42

This problem seems to be a while now with no clear solution: https://community.home-assistant.io/t/dsmr-slimme-meter-problem/15956/4 https://community.home-assistant.io/t/dsmr-broken/255149

Looks like I have the same problem when using a(n active) P1 splitter.

Seems like an issue with receiving the data. Test with screen / minicom / whatever if you really receive telegrams. Please reopen if still broken.
