Yes, I now realise that. I did try some of the calculators, but they are rather complex and need more input than I can provide. Also none seems to deal with sunlight.
I found a general divider that would provide an average value, good enough for what I use it for. But that will still gove nimbers about an factor 35 to high, that is apparently where the constant error is. As far as I understand. So far, I divide by the value and again by 35 which has my station running similar to near by stations.

I am still coping with unreal visual light values... I thought I divided the values down enough to be realistic, but when I compare my values to a station a couple of blocks away, I get strange, extreme differences.
How do I calculate valid watts/m2 and UV indexes?
The neighbors station.
Please note that my highs are off the charts and my lows are lower than his, so it's not just some linear division.
How can I test if the sensor if seen by the pi in the first place? What modifications need to be done to use the software on the GroveWeatherPi setup
From the SDL_Pi_SkyWeather/TSL2591/TSL2591.py file I assume the sensor is on address 0x29. Running the testSDL_Pi_TCA9545.py program I can see something on that address on BUS-3, so am I to assume the sensor is detected indeed?
