I have a MPU-9255 and a BME280 connected to I2C and in the I2C tab I can see the humidity sensor.
The MPU is not present in Compass tab (Detected IMU: empty).
Openplotter in debug mode tell me
No IMU detected
No humidity sensor detected
There is a way (another program or action via terminal) I can test my sensors?
Or it is a know software fault?
Thank you
Roberto

i have a BME280 also it always shows humidity as 0 ..i don't think it reads it or i got some epoxy on it.. it doesn't really matter to me as i should always be in 90% to 100 % anyways..
try this to see if i2c is detectid on the pi in the terminal.
sudo i2cdetect -y 1

This should be a bad connection, any progress on this?

No, any progress. Tomorrow I can run the "sudo i2cdetect -y 1" and I'll report the answer.
In the past days I have reconnected the 2 I2C devices but no difference.

Oh, my fault. I have BMP280, and was under impression that it has also umidity.
Thank you!
Now I have to discover why MPU-9255 is not seen: sensor broken? How can I test it?
i2cdetect report only a sensor ad address 76, which is the one of bmp280...

You should see address 0x68 for mpu9255
check your soldering and connection.
I will send this thread to "How do I?" forum to keep clean the bugs forum

Thank you.
Perhaps a broken sensor... I tryied connecting to SPI and look as some value are read. As soon as I can I’ll try with another sensor working for shure.
