Hi, thanks for all the great work!
I am currently testing with a MPU9250 connected, and there seems to be a problem with an offset?
In the window "alignment" from Calibration PyPilot, the boat is slowly spinning in all 3 axis.
Pitch, Roll, Heel and Heading slowly drift with a couple of degrees per minute.
Image is that of 16-12-2019, both on Pi3 and Pi4 I see the same drifting problem.



On the old image (Openplotter 1.0.0) on the same hardware (pi3): the thing is stable.
Are more people experiencing this?

I'll post the same text also under PyPilot...

I'm seeing a similar behaviour. Reset the calibration of the IMU and set the boat to level and then slowly the heel value increases (about .1 degrees to starboard every 10 minutes or so). Before calibration the vales show at 90 degrees, calibrate and then slowly returns to the original value
