Trigger Data in Templates

Ever wondered what trigger data is available for you when writing automations? Just copy the mqtt.publish service below and put it in any of your automation action section, and it will dump all the attributes and information related to trigger, and state into your mqtt with a topic name "/dump/platform" .

Pre-requisite is to have MQTT configured in your Home Assistant. Use tools like mqttfx to browse mqtt data.

Hope you find it useful!
