Hi all,
I am trying to add QMC5883L sensor to Wemos running 13.1.0(sensors)

running i2cscan, it sees the correct device, but there is no senor output.
I2CScan":"Device(s) found at 0x0d"

I have other devices with the BME280 using i2c and they seem fine.

According to this page

BUILDS - Tasmota

The QMC is not included in any of the pre-built bins. You will need to compile your own

That was it.
If you want to compile your own, I followed this video
All I changed was to uncomment the line below in file my_user_config.h

//  #define USE_LUXV30B                            // [I2CDriver70] Enable RFRobot SEN0390 LuxV30b ambient light sensor (I2C address 0x4A) (+0k5 code)
#define USE_QMC5883L                           // [I2CDriver71] Enable QMC5883L magnetic induction sensor (I2C address 0x0D) (+0k8 code)
