The `mosquitto` broker package ships commandline tools (often as `*-clients` package) to send and receive MQTT messages. As an alternative have a look at [hbmqtt_pub](http://hbmqtt.readthedocs.org/en/latest/references/hbmqtt_pub.html) and [hbmqtt_sub](http://hbmqtt.readthedocs.org/en/latest/references/hbmqtt_sub.html) which are provided by HBMQTT. For sending test messages to a broker running on localhost check the example below:
|
|
|
|
```bash
|
|
mosquitto_pub -h 127.0.0.1 -t home-assistant/switch/1/on -m "Switch is ON"
|
|
```
|
|
|
|
Another way to send MQTT messages manually is to use the "MQTT" Integration in the frontend. Choose the "Configuration" tab, click "Integrations" and click the "Configure" option under the "MQTT" integration. Enter something similar to the example below into the "topic" field under "Publish a packet*.
|
|
|
|
```bash
|
|
home-assistant/switch/1/power
|
|
```
|
|
|
|
and in the Payload field
|
|
|
|
```bash
|
|
ON
|
|
```
|
|
|
|
In the "Listen to a topic" field, type # to see everything, or "home-assistant/switch/#" to just follow the published topic. Press "Start Listening" and then press "Publish". The result should appear similar to the text below
|
|
|
|
```bash
|
|
Message 23 received on home-assistant/switch/1/power/stat/POWER at 12:16 PM:
|
|
ON
|
|
QoS: 0 - Retain: false
|
|
Message 22 received on home-assistant/switch/1/power/stat/RESULT at 12:16 PM:
|
|
{
|
|
"POWER": "ON"
|
|
}
|
|
QoS: 0 - Retain: false
|
|
```
|
|
|
|
For reading all messages sent on the topic `home-assistant` to a broker running on localhost:
|
|
|
|
```bash
|
|
mosquitto_sub -h 127.0.0.1 -v -t "home-assistant/#"
|
|
```
