Stages Power Meter - Erratic Reading

I have purchased a new PM (Stages v2). And as I was doing the FTP test, I noticed that power was having spikes and dips ALL the time. I have the 3 second smoothing option selected in Zwift.


Any idea what the issue might be?

Hi Fadi,

Please ensure that you’ve updated the firmware to the latest version and that you have calibrated the power meter.
