Hello, I am trying to remove the brackets [] at the output of my payload
If I get "27" or "25" it gives me a text result, but the problem is that the sensor reading gives me ["27.500"]
How can I remove those []?
Thank you
You are receiving a json string representation of an array. You can select in the mqtt node to automatically parse this to a javascript object.
Once you have done this you can copy the path to the element in the array from the debug sidebar and use this path in a change node to set your payload to that element.
Perfect, it worked for me the first time.
Many thanks
