Hi,
I am at my wits end trying to get Node-RED connected to Home Assistant server. I have HA and NR running in docker containers on a NUC.
These are the docker-compose.yml
files for both:
version: "3"
services:
homeassistant:
container_name: homeassistant
image: homeassistant/home-assistant:stable
volumes:
- ./config:/config
- /etc/localtime:/etc/localtime:ro
- /var/run/docker.sock:/var/run/docker.sock
devices:
# Conbee II Zigbee device on USB
- /dev/ttyACM1:/dev/ttyACM1
restart: unless-stopped
network_mode: host
version: "3.7"
services:
node-red:
container_name: nodered
image: nodered/node-red:latest
environment:
- TZ=Europe/Brussels
ports:
- "1880:1880"
restart: unless-stopped
volumes:
- ./data:/data
Node-RED version:
nodered | 30 Oct 14:03:23 - [info] Node-RED version: v2.1.3
nodered | 30 Oct 14:03:23 - [info] Node.js version: v14.18.1
nodered | 30 Oct 14:03:23 - [info] Linux 5.11.0-38-generic x64 LE
Whith this configuration, NR tries to connect to HA without success:
nodered | 30 Oct 14:03:24 - [info] Starting flows
nodered | 30 Oct 14:03:24 - [info] Started flows
nodered | 30 Oct 14:03:24 - [info] [server:Home Assistant] Connecting to http://192.168.2.60:8123
As advised by some in the HA forums, I changed the NR docker-compose.yml as follows:
version: "3.7"
services:
node-red:
container_name: nodered
image: nodered/node-red:latest
environment:
- TZ=Europe/Brussels
# ports:
# - "1880:1880"
restart: unless-stopped
volumes:
- ./data:/data
network_mode: host
Doing so, NR connects to HA:
nodered | 30 Oct 14:08:57 - [info] Server now running at http://127.0.0.1:1880/
....
nodered | 30 Oct 14:08:58 - [info] Starting flows
nodered | 30 Oct 14:08:58 - [info] Started flows
nodered | 30 Oct 14:08:58 - [info] [server:Home Assistant] Connecting to http://192.168.2.60:8123
nodered | 30 Oct 14:08:58 - [info] [server:Home Assistant] Connected to http://192.168.2.60:8123
Great, problem solved ! Well, no...
In this configuration, I cannot connect anymore to NR via the 1880 port...
But the port seems to be up and listening...
$ sudo lsof -i :1880
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
node-red 429417 jiheffe 19u IPv4 1682621 0t0 TCP *:1880 (LISTEN)
What am I missing here ?
