### {% linkable_title Commands %}
Short story of that caption: We wait on incoming data from mqtt broker to do some things. We can also use on HomeAssistant input_boolean that trigger a automation to publish a custom command to mqtt topic they can process multible things in one add-on.
Our Dockerfile need to install:
```
RUN apk --no-cache add tzdata jq mosquitto-clients
```
Now we can process it with `run.sh`:
```bash
#!/bin/bash
set -e
CONFIG_PATH=/data/options.json
# possible options for processing
MQTT_SERVER=$(jq --raw-output '.server' $CONFIG_PATH)
MQTT_PORT=$(jq --raw-output '.port' $CONFIG_PATH)
TOPIC=$(jq --raw-output '.topic' $CONFIG_PATH)
USER=$(jq --raw-output '.user' $CONFIG_PATH)
PASSWORD=$(jq --raw-output '.password' $CONFIG_PATH)
# read data
while read -r message
do
if [ "$message" == "on" ]; then
/do_command_on.sh || true
else
/do_command_off.sh || true
fi
done <<(mosquitto_sub -h "$MQTT_SERVER" -p "$MQTT_PORT" -u "$USER" -P "$PASSWORD" -t "$TOPIC" -q 1)
```
