It works mate. Thanks for the clarification. I’ll be sure to remember this, so we don’t end up having to navigate through all the possible errors Node-RED could give again.
As for negative values I’m in Australia, so I probably won’t worry bout it. I have seen your post here however, so if I end up travelling into the alps, I’ll be sure to look into that. I had to check and the lowest on record the temperature in Adelaide is -0.4 degrees Celsius. Don’t worry, we compensate for that. Today’s temp was only in the low 40s.
