@Ken the API doc is up to date, nothing new/undocumented, so yeah, the Guiding Assistant is not remote-controllable at this time.
@esazx, I don’t think your imaging is likely to benefit from running the Guiding Assistant each night. It should be adequate to run the G.A. once on a night with average or better-than-average seeing. If seeing degrades so far that the guider is chasing the seeing more than it would have with a fresh G.A. run, then your subs are going to be low quality anyway (due to the poor seeing), and you probably won’t even care about the guiding.
I’m basing this on personal experience with my own imaging setups and from looking at lots of people’s guide logs. In my case, I set my min-move values once based on a night of average seeing and after that I never touch them. We’re willing to be persuaded otherwise, but let’s take it up in the PHD2 forum, or on the github issue you added.
