Node RED Docker not connecting to HA, logs empty, no autocomplete

General

I haven't been successful trying to get Node RED (node-red-contrib-home-assistant-websocket) to connect to Home Assistant for a while now.

I'm running HA 2022.12.6 and Node RED 3.0.2 with node-red-contrib-home-assistant-websocket 0.47.1.

Running the node-red container in bridge mode with port 1880 forwarded results in not finding the HA instance in the web UI. Adding the server manually nets: "Deploy a valid server config for autocomplete to show results."

When running it in host mode, the HA instance is found. Adding it still nets the above-mentioned message and no autocomplete results.

Running

sudo docker exec -it nodered bash
ping *homeassistant*
echo < /dev/tcp/*homeassistant*/8123

works both in host mode and in bridge mode.

Configuring the logging output in data/settings.js to

    logging: {
        console: {
            level: "trace",

does not help either.

docker compose logs -f nodered

does not yield any info regarding the home assistant integration.

Docker is running on a single host machine. Using one compose file versus two separate ones does not change the outcome.

compose.yaml for node-red

services:
  nodered:
    container_name: nodered
    image: nodered/node-red:latest
    restart: unless-stopped
    volumes:
      - ./data:/data
    ports:
      - "1880:1880"

compose.yaml for Home Assistant

services:
  homeassistant:
    container_name: homeassistant
    image: "ghcr.io/home-assistant/home-assistant:stable"
    restart: unless-stopped
    volumes:

I've forgotten :
to access HA with nodered , when launched, install the "node-red-contrib-home-assistant-websocket" palette, and use don't thick the "Using the Home Assistant Add-on" box. Just create a long term Access token in HA and use it when creating the HA server in nodered. (and install nodered companion in ha too)
This is functional for me.

Hi and thanks for replying.
Your compose file (at least the parts concerning HA and node red) matches mine except for the TZ env variable which I added now. Still no bueno :frowning:
