Light sensor readings

I have a question about the light sensor on the Pulse One. I have a 600 R-spec it is dimmable, I have it at 20% (2 clicks) and the pulse is reading 92%. my question is the light senor supposed to read 20%. I tried the cardboard roof but it was reading all over the place for ex. 30% anywhere from 70%. Am I doing something wrong or just overthinking??? Guide me in the right directions

Hey @GeMann!

The light sensor on the Pulse One is a relative light sensor (LUX) and it’s primary purpose is to ensure your lights are coming on and turning off at the right times. You would need a PAR meter (like the one in the Pulse Pro) to really understand the strength of your lights in context to your plants.
