mqtt2HomeAssistant

hallo there,

I am fairly new to HomeAssistant and am slowly migrating my home automation to HomeAssistant.

Because I am familiar with LUA and DzVents (Domoticz) I would like to use some more scripts from Domoticz and send their data via MQTT (Mosquitto and NodeRed) to HomeAssistant.

My question: how can I make a graph in HomeAssistant listen to a topic in NodeRed?

So that the data is updated directly from MQTT in a graph in HomeAssistant.

Thanks in advance!
