Hi @Robbie98
can you share what the Debug output shows for the message coming from the SenseHat node? If I remember the node correctly (I did write it....), it sends a payload of `{temperature: 12}`.
I can see you have added a JSON node - that will be converting the object to a string. That will make it harder to access the individual values inside the string.
I _think_ you just need the Change node between the SenseHat node and the gauge node, configured to set `msg.payload` to `msg.payload.temperature`.
