Zigbee2MQTT make me crazy please help

My best advice would be to implement a long (more than 1m) USB extender cable. Even on a stable system. Moving the coordinator far away form any electrical devices.

Good morning, Today I’ll buy one because it stopped again. Do you suggest a 3.0 extension or is a 2.0 ok?

better than a 3.0

2.0 is fine, however do not think it makes a lot of difference.

The suggested USB extension cable is a passive extension cable, NO hub/electronic amplifying or anything.

Just a cable.

Trying to add disable_automatic_update_check option but it does not seemto make any difference. Where do you actuallu add it? I have it in my /root/config/zigbee2mqtt/configuration.yaml which looks like this. But updates available prompt in Settings in HA still says that 3 devices have updates. Any clue how to disable OTA check properly?
