HA stopped getting values from water meter (flowiq2200 with nanocul)

[falkio8]

Ok my setup which worked more or less flawlessly since weeks:

Flowiq 2200 Watermeter with AES key from provider
Nano CUL 868mhz USB Stick (2m distance with direct sight to flow meter)
WMbusmeters Addon
MQTT Broker installed but needed no configuration and detected the flow meter flawlessly

This setup worked till yesterday in the evening, I didn´t get new values since 21:37 (24h) o´clock.

I don´t get much intel from the logs of wmbusmeters or mqtt because I don´t undestand much of it. Is there any possiblity to debug the setup? Check the connection between Nano Cul and the flow meter? Check the connection between Nano Cul and the wmbusmeter addon? Check the connection between wmbusmeter and MQTT Broker?

From my point of view I didn´t actively changed anything since yesterday. Woke up and values were unchanged in HA despite the real values on the meter changed.

This is my setup:

All those values are not updated since yesterday.

This is the wmbusmeters log:
c8a990ad_wmbusmeters-ha-addon_2024-12-09T10-47-45.268Z.log
This is the MQTT log:
core_mosquitto_2024-12-09T10-50-39.661Z.log

Pretty helpless right now on how to debug this problem. Restarted HA a couple of times as well as the addons itself. Flowmeter values didnt update.
Thanks in adavance for any hint!!!

Its working again but only after I completely reset the wmbusmeters addon and started to setup the meter from scratch. So what went wrong? Why did the addon stopped working and needed a factory reset?
