For me, in the mount tab (Ctrl K, tab mount, i unpark mount, goto a star, the unpark button is grey (mount is really unparked)
If I click on the park button, it instantly turns grey (parked mount) as the mount continues to move to the park point.
I can click on the unpark button while the mount is not yet parked (it is moving to its park position). So the mount stops where it is. and goes into tracking.
Maybe this is the normal operation.
The only problem is that the automatic sequence stops when the mount is not yet parked.

My shelter can send the park order to the mount directly on OnStep (by WiFi).
I can use this solution.
I do not park the mount at the end of the sequence but only the shelter (which will park the mount for him).

I just started a sequence that makes the following:

Unpark
Track and Focus on a star
take 10 dark
take 10 flat
take 10 pictures
track and focus on another star
take 10 dark
take 10 flat
take 10 pictures
park
shutdown

and seems to work as expected (I use ccd simulator)

Where I am not happy is that Ekos still states Slewing instead of Parking but this is most probably deep in Ekos not Indi so I am a bit dry on that.

Still to test some other things and set-up a debugging ...
time to sleep

Hi Claus,I did another test this morning.A sequence:- Unpark- Track Venus- Take a suite of shots- Track Mars- Take a suite of shots- ParkI include as attachment the logs so that you can see whats going on.For me everything works fine but there might be some confusion between what Ekos Scheduler reports and what the actual TrackState is.At end of sequence it says mount parked but in fact it refers to the scheduler not to the TrackState[2021-07-09T12:03:05.677 CEST INFO ][ org.kde.kstars.ekos.scheduler] - "Job 'Mars' 5x1\" Luminance completed its sequence of 0 light frames."[2021-07-09T12:03:05.683 CEST INFO ][ org.kde.kstars.ekos.scheduler] - "No jobs left in the scheduler queue."[2021-07-09T12:03:05.684 CEST INFO ][ org.kde.kstars.ekos.scheduler] - Starting shutdown process...[2021-07-09T12:03:06.740 CEST INFO ][ org.kde.kstars.ekos.scheduler] - "Parking mount in progress..."[2021-07-09T12:03:07.432 CEST DEBG ][     org.kde.kstars.ekos.mount] - Mount status changed from  "Tracking"  to  "Slewing"[2021-07-09T12:03:07.438 CEST INFO ][     org.kde.kstars.ekos.guide] - "Mount is moving.

I don't use Park/Unpark, and therefore don't see the same symptoms that you do.

But I did notice one odd thing with the most recent stable KStars from Jassem's PPA, and perhaps from one release before that.

Previously, when I started a slew, I had a notification that said "Mount reached destination", but only when the mount has reached the target.

Now, when I start a slew, that notification is displayed immediately when the slew is just starting.

I don't see any other ill effect.

But I think this is related to what you folks are seeing.

Khalid,

I didn't use the scheduler till now so I was not aware about all these things.
But now that I try to reproduce the behavior Claus is seeing I discover a lot of things where I get more and more confused.
So far I did check, Telescope Status is only managed by "TrackState" and running Indi in debugger it appears that this variable is reflecting what wee expect (the firmware status IDLE, SLEWING, TRACKING, PARKING and PARKED) but Ekos shows some other states like "Moving E, Moving W .... so what Ekos shows is definitively not directly reflecting the Firmware state and may be this is what creates confusion.

But fo now I did some tests whith the Scheduler and it seems to work as expected with the version I have on my git
github.com/azwing/indi

@ Claus,

I don't use CDC. Does it have a scheduler?

@Alain

Yes CCDCiel has a good scheduler.

James,

I tested the "own-goto" branch and I found ti does work except for the unpark issue.

I also checked the behavior whithout testing (strcmp(OSStat, OldOSStat) != 0) no change so test might be overkill but for sure not the reason.

So far all my tests with Scheduler were successful, the only change I made in my code is the SetParked(false); in case of failure but only if if (isParked()) is true

I've downgraded my setup:
Ubuntu Mate 20.04 -> Ubuntu Mate 18.04
And compiled indi drivers 1.8.9
And all is working \o/
I'm waiting for Indi 1.9.9 for upgrade

Claus,

I understand your downgrade to a previous version of Indi, but I see no rationale for the downgrade of Ubuntu.
Some library issues or related to Kstars?

No, with Ubuntu 20.04 i have issues with wakeolan and i don't want to use snapd.
Kstars seems to work fine with Ubuntu 20.04 (tested with my desktop on Kubuntu 20.04).

I've found an another solution for my problems of park/unpark:
- Install indi drivers 1.9.1 (latest)
- Get the 1.8.9 indi sources
- Get the 1.9.1 indi sources
- copy indi-lx200_OnStep 1.8.9 in source code of indi 1.9.1
- Compile indi 1.9.1
- Copy the compiled indi-lx200generic in /ust/bin/

And it's work \o/ Park and unpark are OK.

Claus,

The last version I have online on github.com/azwing/indi is working fine.
I tested many cases in Ekos and using scheduler.
Most probably it will be the base for the next pull request if James agrees.
So it would really be nice if you could make a trial.

regards

Thank you so much.
I will test.
Anyway, I still have the old version compiled in case of problem
Now, it's easy to switch of versions (production and devel ).
