- if all goes well you will see printer and bunch of sensors ( 25~ ) in Integration -> MQTT
- one of those sensors is Octoprint Print Status which will give you all sorts of sttauses like ERROR , PRINTING, PAUSE etc…
- you can create simple status change automation on this status change to send whatsapp or anything else.
