Neither of the two devices worked - sending them both back!

Not hmc5883l, it is qmc5883

Despite the HMC markings, it's actually a knockoff. As somebody else said, when running an i2C scanner, if you see 0x0D it's a QMC, and 0x1E it's a HMC part. Needed to supply the QMC5883L Magnetometer instructions on ESPHome to make it work. But it does seem to work once configured correctly, so there's that.

The magnetometer chip is QMC5883L and requires different programming. Also, the supplied pins are ferromagnetic, so they may distort magnetic field near the sensor chip.

If the IC marking is to be believed, these are in fact HMC’s, not QMC’s as the other reviews would indicate. L883 = HMC, whereas 5883 is QMC. I needed QMC’s, so I listened to the other reviews and assumed that’s what this would be, but this seller must’ve switched to the right chip since those other reviews were made. I did not test the chip to see if it’s actually a QMC, but I won’t bother, seeing that if the marking is incorrect and has been mislabeled, this chip is not trustworthy to begin with.

As of December 2022 they are shipping QMC5883 units. Easy to tell ... just run the i2C scanner. If you see 0x0D it's a QMC, a 0x1E it's a HMC part.That said, I proceeded to test it out. Worked ok and is pretty stable, needing less filtering than a AK8975.

Worked well after taking hours to figure out that it was a QMC magnetometer, and not a HMC. Also you need to calibrate it every time before you use it if you want accurate readings. Although github has a easy to use calibration program that outputs a line of code that you then insert into your own code to make the process super easy.
