Hey Guys, Need help.
Im using a Nodemcu with Tasmota installed to send a DS18B20 temp probe data to node red. I have been able to have the info come into node red but the payload isn't broken up. I want to be able to use the temp and the time stamp for controlling a reptile cage heating elements.
My thinking was to put it through a change node and address the value in the array. But it seems as though there is no array in the payload and its just text.

Set your MQTT nodes output to "a parsed JSON object" and you are there.
