Good morning, it’s already solved thanks to fellow Hellis81. I copy the message he sent me:
I did a test and I believe your payload is a string that looks like an object.
try this in the switch node: payload["CIO204.12"]
I tried to send two different messages one was
payload.CIO204.12
the other
payload["CIO204.12"]
It seems CIO204.12 is string given the debug output above.
