I used Johan’s excellent arcticle Adding a Bresser 5 in 1 sensor to Home Assistant to integrate a Bresser 5in1 weather station.
Acquired supported DVB-stick, installed rtl_433 and configured to listen to 868.3MHz and send data to local mosquitto-broker.
According logs everything works fine until listening begins. Unfortunately that is where logs terminate, nothing gets received at all:

[10:55:18] WARNING: rtl_433 now supports automatic configuration and multiple radios. The rtl_433_conf_file option is deprecated. See the documentation for migration instructions.

For testing purposes I used same stick and started local instance of rt_433 on Windows10 with exact same configuration as in Hass. Log looks very similar but here data is successfully received:

Using DVB-stick on Windows10 I have proven it works and is supported as well as weather station is sending data.
Can anyone give any hint what could be the reason for the behaviour within home assistant and what else I could try to overcome the problem?!
THX in advance
To be complete: HASS is Generic x86-64 installation on HP thin client with two USB devices connected: 1. Sonoff-Zigbee3.0-Dongle, 2. DVB-stick
