MQTT Connection Refused #348
Description
Started using this integration again as the other MG integration is not longer being developed. I have updated my config (although nothing has changed) and im having issues with the connection from the container to MQTT.
Docker Compose
services:
saic-mqtt-gateway:
image: "saicismartapi/saic-python-mqtt-gateway:latest"
container_name: saic-mqtt-gateway
hostname: saic-mqtt-gateway
env_file: .env
restart: always
#volumes:
# - ./charging-stations.json:/usr/src/app/charging-stations.json
networks:
default:
name: $MY_DEFAULT_NETWORK
external: true
reverse_proxy:
name: $MY_REVERSEPROXY_NETWORK
external: true
.env
# GENERAL
MY_DEFAULT_NETWORK=home_automation
MY_REVERSEPROXY_NETWORK=reverse_proxy
MY_DOMAIN=mydoman.fqdn
TZ=Europe/London
PGID=996
PUID=1100
# SAIC-MQTT-GATEWAY
MQTT_URI=tcp://mqtt-mosquitto:1833
#MQTT_URI=ws://mqtt-mosquitto:9001
MQTT_USER=myuser
MQTT_PASSWORD=mymqttpwd
SAIC_USER=myuser
SAIC_PASSWORD=mypassword
MQTT is anonymous but ive also created a user/password combo for this connection which i can connect fine with from my phone.
mqtt-mosquitto is the docker DNS address for the container and is on 172.18.0.2 (same docker network) so i dont see how its a routing problem.
If i switch to websockets i get an error saying its trying to write to a closed socket - unsure why.
I had this before and had to set a username and password which i have done so im a bit stuck
Error log upon docker compose up
