Raspberry Pi 3B + HA in docker-compose + MQTT + OpenZWave: connection issue

Hi community!
I am pretty sure I have scavenged entire internet for my issue, but seems like no one tried what I am doing right now.
I have RaspPi running following Docker Compose containers:

  • HA as “raspberrypi3-homeassistant”
  • Mosquitto as “eclipse-mosquitto” with ports 1883,8883, no login, default config
  • ozwdaemon as “openzwave/ozwdaemon:latest”

I have GoControl husbzb-1 stick for Z-Wave plugged in.

I was able to ping mosquitto from terminal with nc -zv 0.0.0.0:1883 and therefore this is what I used in configuration.yaml - if I try to set it up using UI, it says it cannot connect.

Hoping that this is it, I headed to UI and added OpenZWave integration, which added just fine. When I try to “configure” it, I get We couldn't find an OpenZWave instance. If you believe this is incorrect, check your OpenZWave and MQTT setups and ensure that Home Assistant can communicate with your MQTT broker.

It looks to me that issue is with MQTT, but the logs are clean (I had errors at the beginning but nothing new now). Tried to install some clients but nothing works on RaspPi, even mosquitto_sub/pub. Stuck here.

Does anyone have any ideas how to go forward from here? Maybe docker is blocking MQTT but couldn’t find how it’s possible?
