Hi,
I had 2 devices loaded in to Home assistant through “DSMR Slimme lezer” (gas and electricity). The IP address changed for this device, since I couldn’t find an easy way in the UI to change the IP I removed the original device and re-added the device with the new IP. Now the electricity meter is working correctly again but the gas meter keeps stating that the value is Unknown.
When i look in the debug output i see the following logs:
2023-10-25 12:09:37.349 DEBUG (MainThread) [dsmr_parser.clients.protocol] received data:

When i parse this in the same parser DSMR uses I can read the gas value:
from dsmr_parser import telegram_specifications
from dsmr_parser.parsers import TelegramParser
telegram_str = (
# The value from above
)
parser = TelegramParser(telegram_specifications.V5)
# see 'Telegram object' docs below
telegram = parser.parse(telegram_str)
print(telegram.HOURLY_GAS_METER_READING.value)
print(telegram.HOURLY_GAS_METER_READING.unit)
> 8441.814
> m3
Now I don’t really know how homeassistant uses this data after parsing. Does anyone have any idea where this could go wrong or any pointers for where to look? Thanks 
Edit: also the entry in my config_entries shows the correct id (I think):
