When I first got my drone the barometer was very accurate, and height readings would stay the same when hovering. I have noticed recently that my barometer readings have been fluctuating +/- 2 meters even when hovering indoors without change in air pressure. In under 10 seconds I have seen it climb a meter even though the drone is using VPS and is hovering perfectly. I have reinstalled firmware with dji assistant and calibrated both IMU and compass. How much fluctuation do you guys see in the barometer?
