How to use streetmerchant in docker

[norey]

I'm running streetmerchant as a docker container on a headless server like so:

root@dockerh:/opt/streetmerchant# cat docker-compose.yml
services:
  streetmerchant:
    image: ghcr.io/jef/streetmerchant:latest
    container_name: streetmerchant
    ports:
      - "8282:80"
    env_file:
      - dotenv
root@dockerh:/opt/streetmerchant# grep -E '=[^$]' dotenv
MQTT_BROKER_ADDRESS=192.168.50.100
MQTT_BROKER_PORT=1883
MQTT_PASSWORD=password
MQTT_USERNAME=user
OPEN_BROWSER=false
SHOW_ONLY_MODELS=founders edition:5090
STORES=bestbuy
WEB_PORT=80

I tested the MQTT notification like so:

docker run -it --rm --env-file ./dotenv ghcr.io/jef/streetmerchant:latest test:notification:production

And confirmed that I got the correct example data.

Since the model I'm looking for is OOS, I wanted to test other models. So I went to the WEB UI and saw the Brands and Series columns all selected. I found two models in stock so I unchecked everything from the Series column and kept 5080 and 5070ti. Also checked triple fan oc and triple fan in the Models column.

Here are the models in stock

I clicked the Save button on the page and waited. Nothing happened, my MQTT server didn't receive anything.
What am I missing? Am I using it correctly?
