HA: ValueError: invalid literal for int() with base 16: '140W' #65

Closed matthijsberg closed 8 months ago

matthijsberg commented 3 years ago

HI,

I'm using this in Home Assistant. I get quite some CRC errors (2020-12-11 21:01:13 WARNING (MainThread) [dsmr_parser.clients.protocol] Invalid telegram. The CRC checksum '45204' does not match the expected '29681') and the error below. I connect to a Landis & Gyr E360 via DSMR 5 directly connected. It looks like I get a value in the CRC field? most of the error are CRC, sometimes I get this:

2020-12-12 14:11:47 ERROR (MainThread) [homeassistant] Error doing job: Exception in callback SerialTransport._read_ready()

    expected_crc = int(checksum_hex.group(0), base=16)
ValueError: invalid literal for int() with base 16: '140W'

Let me know if you need more information (and some pointers where to get it) if needed.

I also have this problem, even though the integration seems to function well otherwise.

What would help if you could add raw telegram data. User lowdef explained how that could be done here: https://github.com/ndokter/dsmr_parser/issues/91#issuecomment-962428443
