@arendst
are any problems with the PR?

Still investigating the used libraries. I noticed a pow math function using 5k code. AN alternative is available and provided by Tasmota. Needs lib update though. Not a big problem but I need to find time to do it.

ah ok. thanks for info.
at the moment, the driver don't use "readLuxNormalized" and "readWhiteNormalized" with the math-pow function for the readings.
If i had time, i did a integration without Libary.

Guys, wondering if you can help. I'm trying to use both a bme280 and veml6075. I compiled my own tasmota with various versions up to 8.3.1.3. both sensors show up in the i2cscan command but if I comment out #define_bmp in the build the veml6075 shows up in main menu. If I don't bme280(same with bmp280, tried both) shows instead. Do you have any suggestions of anything I can try? Thanks.
