What is the output of the mqtt node? a string, json?

#

a string ... so say if the message is "hello world" or "raining" "im home" that would go into the sensor as a text

#

and i dont understand what a json really is

If you have the Node-RED custom component, https://github.com/zachowj/hass-node-red/, installed in Home Assistant. You can use the sensor node, https://zachowj.github.io/node-red-contrib-home-assistant-websocket/node/sensor.html, in Node-RED connected to the mqtt node and it will create a sensor in Home Assistant and set its value from msg.payload of the mqtt node
