I have various luminance sensors through out my house and want to record what the luminance level is during various hours of the day. (6AM, 8AM, noon, 5PM, 8PM, and 10PM). The reason I want to do this is because it appears as though each manufacturer has a different scale they use for luminance and I want to create apps based on a luminance value. Instead of using a trial and error approach, I want to record each sensors value so I know what to set each one to. I know the numbers won’t be exact, but I just need to know a rough starting range for each time listed above. IFTTT only records if I say write to spread sheet if luminance is above or below a certain value. This would give me a huge spread sheet and I only need values from certain times. Any suggestions on how to get this data?
