The other odd thing is that I had to go into the onstep web page and hit the flip now button. After that it worked- BUT then PHD2 did not flip the calibration data and i had to recalibrate, though I could have just clicked the flip data button.
Definitely seems like either I have a setting wrong, or the pier side is not reported right to SGP / PHD2
I am using POTH as my hub BTW - seems to be working fine now.
