I have used dragscript successfully to capture data for a whole night when the forecast said no rain and I was fairly confident there would be no issues. The system successfully coped with cloud, retrying to acquire the target and continue imaging.
Now I have added a weather station, so that I can close the observatory roof when conditions are Unsafe. This means I have to use Suspend and Resume.
The dragscript I came up with did some of the things I expected, but also some things I don’t know how to correct.I followed some of the samples here and used this:

I am using VIking with a Velleman VM110n interface card, to control roof and flap. Hence the relay on-off instructions.
I divided the filters into separate sequences to try and avoid VOyager going back to the beginning of a complex sequence if interrupted.
In last night’s run the first three sequences ran OK. After starting the fourth sequence clouds came in and the weather station switched to Unsafe triggering a Suspend.
My first problem is that the cloud was fluctuating rapidly around the Safe/Undafe boundary. This caused a sequence of Suspend followed immediately by REsume, then Suspend again and so on. The system was bouncing between roof and flap open and roodf and flap closed as fast as it could.
Question - what do I need to add to prevent a Resume until the weather condition has been safe for at least 5 minutes? None of the options in the Emergency Suspend configuration seem to be useful. WAIT SAFE seems to be the answer, but I don’t know where to put it.
Later on things stabilised and conditions were Safe for the rest of the night. However, some cloud obscured the target later on and Voyager attempted to reacquire the target using Precise Pointing. Because of the cloud platesolving failed, and after three tries an error was detected and that sequence stopped and control moved to the next sequence. Which also failed platesolving. Because of the Repeat Block instruction at line 31, Voyager started with the first sequence again, so I captured a few more subs with the Lue filter (Line 5). The Dragscript ended at 04:00, executing Blocl: Terminate (line 32).
If I want to go back to the filter I was using when the interrupt, came should I put each filter sequence in a separate Block? I could then use a Repeat Block until Time to spread my efforts on each filter across the night. Perhaps allowing 1 hour for each filter, for example. Or use the number of completed subs in the sequence file to repeat each filter block until the sequence is complete or the imaging night is over.
Is that a way to do it, or have I missed something very simple.
Thanks in advance for any suggestions.
