Measurement of light/radiation

[Copitano]

Does anyone here have experience getting the OPT101 Light Analog Light Intensity Sensor Module Single Chip Photoelectric Diode 14KHz CJMCU-101 operational.
Had it for a while, but I can't find much with google about connecting the thing to an RPi via a NoduMCU ESP8266 v3. In ESPeasy I can only find the BH1750 and the TSL2561. I can of course just order it, but I have the OPT101 lying around

Some aspects for installation of interface-software for SI1145 have become slightly easier with time:
