MQTT Publish service
The MQTT component will register the service publish
which allows publishing messages to MQTT topics. There are two ways of specifying your payload. You can either use payload
to hard-code a payload or use payload_template
to specify a template that will be rendered to generate the payload.
{
"topic": "home-assistant/light/1/command",
"payload": "on"
}
{
"topic": "home-assistant/light/1/state",
"payload_template": "{{ states('device_tracker.paulus') }}"
}
