BH1750/ GY30 on i2c

[Henkje1234567890]

Hello

i have a GY30 sensor connected to mij esp, firmware on the esp is r120
I have configured it as a BH1750, but no readings.
when i look with the I2C scan, it says:
0x23 BH1750 Lux Sensor
but no value.
when i switch Sda and scl, no reading in the I2C scan, but a value on the screen. this one is very high, and doesn't change
i have the same with another I2C sensor (BM280)
Whats goiing wrong with it??

I have a similar issue with R130 using bare ESP-01 (black)...

In R120 it shows the values and detects the sensors (BME280 and BH1750), but in R130 detect the sensor (BME280), but without any values shown.

If I return the R120 then everything is working again!

Any toughs?!

Is this problem still "actual"?

This is not a problem I have ever seen, But I only have various ESP-12 models and a couple of Olimex Mod-Wifi boards.

I have a BME280 running perfectly every day for months, no problems.
