@DanielXYZ2000 I applied this to my sensors and I'm getting the following in my log

Error parsing value: 'dict object' has no attribute 'humidity'
Error parsing value: 'dict object' has no attribute 'temperature'
Error parsing value: 'dict object' has no attribute 'heatindex'

Is it possible to ignore these attributes when they are not passed by the sensor JSON without generating an error?

@epleypa For me its compiling fine without any errors. Check if you have the libaries installed for ArduinoJson.h. I have the Version 5.11.2 installed
