10Micron LX200: different parking behavior when using Scheduler or INDI driver

Hi Wolfgang,
issuing the Park command from the Mount Tab works as expected:
From Mount Tab:

2021-10-16T09:07:21: [INFO] Mount is parked. 
2021-10-16T09:07:21: [INFO] Gstat changed from 2 to 5 
2021-10-16T09:07:13: [INFO] Gstat changed from 0 to 2 
2021-10-16T09:07:12: [INFO] Parking. 

From parking to parked is 9 secs only because the mount was close to parking position.
With the same configuration I checked from the Scheduler:

2021-10-16T11:20:27 Dome parking failed. Restarting operation...
2021-10-16T11:19:54 Parking dome...
2021-10-16T11:19:53 Mount parked.
2021-10-16T11:19:52 Parking mount in progress...
2021-10-16T11:19:51 Cap parked.
2021-10-16T11:19:49 Parking Cap...
2021-10-16T11:19:48 Warming up CCD...
2021-10-16T11:19:48 No jobs left in the scheduler queue.
2021-10-16T11:19:47 Job 'NGC 4960' is complete.
2021-10-16T11:19:38 Job 'NGC 4960' capture is in progress...
2021-10-16T11:19:38 Job 'NGC 4960' slew is complete.
2021-10-16T11:19:37 Job 'NGC 4960' is slewing to target.
2021-10-16T11:19:36 Mount unparked.
2021-10-16T11:19:32 INDI devices connected.
2021-10-16T11:19:29 Scheduler started.
2021-10-16T11:19:29 Scheduler is awake.

The parking distance was the same as the previous test. But here the Parked status is immediately after the Parking command.
(the 2hrs time offset between the 2 tests is due to the mount working in UTC and Ekos using local time)

Thanks
Ferrante

Hi Ferrante,
sorry for the late response, but this confirms what I thought. It looks like the being a driver issue.

Fixing this without a 10micron is very difficult. Are you more or less familiar with building from sources and debugging? I could assist remotely. Just send me a PN.

hi Wolfgang,
the behavior is exactly the same as reported in this thread: 
indilib.org/forum/ekos/10807-scheduler-w...ck-policy.html#78185
In this case it's a different mount (CEM70) so it's not likely a 10micron driver issue.
But I can build and debug the 10 micron driver if needed.

hi Wolfgang,

sorry to bother you with this issue again, but I still struggle to understand the LX200 driver/Scheduler interaction when the shutdown procedure runs.
I see a different behavior when switching from LX200 mount driver to Simulators (Simulators has the expected behavior so the issue is likely on LX200 side), see logs below.

I'm not familiar with the scheduler code, what triggers the 'mount parked' status? It would help me to understand if the LX200 driver is issuing the wrong message.

It seems that the scheduler sets the mount as parked at 21:00:42.708 when the LX200 driver is still parking ('Gstat changed from 0 to 2'*).
But the LX200 driver issues the mount parked message ~25 sec later 21:01:07.119 ('Gstat changed from 2 to 5'*).

While with simulators, the driver and scheduler act as expected.

Hi Ferrante,
that's really weird. It indeed looks like the 10micron driver has a problem reporting the parking process. Could you please check what happens when you manually press the "PARK" button in the INDI dialog? The sequence should be the following:
 
 
 

As long as the mount slews to its parking position, the LED should turn yellow and switch to green as soon as the parking position has been reached.
Cheers
Wolfgang

hi Wolfgang,
you're absolutely right: The parking light is always green, also during slewing and parking. But the messages in the log are reporting parking and parked correctly (see attachments).
So the scheduler rely on the status light been green/yellow to proceed to the next shutdown step? isn't there a 'parking status' variable in Ekos? 

Thanks,
Ferrante

Sure, there is a parking variable (and maybe even more than one :-) ) But this variable is derived from information the INDI driver sends, which is displayed in the INDI driver tabs. As you could see from your screenshots, there is no difference in the Parking variable between PARKING and PARKED.

That's why the scheduler assumes the mount being parked although the slew is in progress. The PARKING state is signaled by "Park(ed)" selected and the status LED is yellow. As soon as it turns to green, the state changes to PARKED.

It looks like we need to fix the INDI driver for 10micron.

Looking at the code seems that the park() method is not managing lights. 
I will open an issue on github providing these informations. Probably Jasem should look into it because the bug could also be in the parent lx200 and I immediately got lost in the class hierachy.

Thanks a lot for your help.

I did a first check in the code. For me surprisingly LX200_10MICRON is derived from LX200Generic and not from LX200Telescope, in contrast to the telescope simulator. Maybe that change would help, but I do not have a mount for testing.

@Ferrante: if you want to test it, I could make these changes on my INDI fork.

 it seems that Jasem already fixed this issue as part of another one.
github.com/indilib/indi/issues/1582

I will test and report here if it works fine with the scheduler as well. thanks again for your support.

Ferrante, are you still having issues? Last night with the new scheduler I ran into some strange mechanics and I wasn't able to park at the end of my night. It tried 5 times to run the park command but it failed for some reason. I need to look at the logs when I get home.

hi Chris,

I'm still having issues but they are not related to mount parking per se. The mount parks correctly when the scheduler asks to.
The issue is that while parking the driver set the mounts status as 'parked'. So, for example, the roof starts closing before the mount is safe in the parking position...

From which tab you run the park command?
Do you also have a dome/roof? in this case check if there's any 'dome locks' flagged.
