I get this error when I try to import the blueprint:

Invalid blueprint: expected str for dictionary value @ data['blueprint']['input']['exclude']['selector']['entity']['device_class']. Got None

Hi, thanks for your work. I wanted to ask if anyone is using labelled to exclude from the report? I have tried but it doesn't seem to be working

I'm using labels to exclude a couple of labs devices (nspanel01, Double Aqara Switch) that have been offline for a while along with the two plant sensors and the exclude does not work as shown by the screenshot.

Same here. Alexa devices/entities doesn't seem to work as it should. Label exclusion doesn't work either.

Labels are....kind of working? Tuya devices are showing up that are mains powered as well.

I made a fork here... https://gist.github.com/Ltek/0c9cecf632b9c32915130680d834bcf7

Updates are...

• Excludes are working
• According to my testing, its also a lot faster execution.
