stefanastro Because in the wintertime I didn't have any issue.
In Winter, you were running "Standard Time." The only time ASIAIR understands.
The ASIAIR has a problem undertanding time because it derives time from "Local Time" instead of directly using UTC that is obtained from iOS and Android APIs. If it had used UTC instead of local time, none of these problems with Meridian flips would occur.
What you can try to do is to use your Mount's handcontroller and check if
1) UTC is correct, and Longitude is correct. If they are correct, you are done since most mounts use UTC and Longitude to determine Local Sidereal Time.
If not,
2) see if you can set the UTC (some mounts have GPS, and you can simply depend on that). Ditto Longitude, and mounts with GPS can set that for you too.
if the mount's UTC is wrong, try
3) set the Local Time to the true Local Time minus one (i.e., set the time as if it is still Winter), AND set the UTC offset in the mount so that it corresponds to the UTC offset under Standard (Winter) time (it will also be 1 hour different from UTC offset under Daylight Saving Time).
After connecting with ASIAIR, check to make sure the ASIAIR app does not modify these two numbers behind your back.
As a sanity check, place your mount so that the OTA points to a location about an hour east of the Meridian (you can use an inclinometer against the OTA tube -- each hour corresponds to 15 degrees of incline, if your mount does not have setting circles on the RA axis). There are digital inclinometers at Amazon for less than $20 that are more than accurate enough for this kind of measurements. I have this dual axis inclinometer since it saves time when leveling a tripod, but you can just go find a $15 inclinometer if you just need to know the incline of the OTA tube.

Then go into ASIAIR AutoRun and set up a fake autorun and see what it reports as the time before the next Meridian flip. If your OTA is tilted 15 degrees east of the Meridian, and the AutoRun says you are 60 minutes (time) from a Meridian flip, then the times in the ASIAIR and the mount are in sync. (i.e., 15 degrees per 1 hours of time to Meridian).
