Alain & Khalid
The way how Ekos works in relation to medrian flip during exposure can be found in the following youtube video
Replaying this procedure i discovered yesterday during clear sky that this is not working with the OnStep.
It looks like that a initiate Median flip is not send to the mount which caused the following error
2019-01-20T22:59:11 Retrying meridian flip again...
2019-01-20T22:59:11 Telescope meridian flip timed out. Please make sure your mount supports meridian flip.
2019-01-20T22:57:41 Current hour angle 0,02 hours exceeds meridian flip limit of 0,02 hours. Auto meridian flip is initiated.
0.02 is less the the 1 degree I defined in the OnStep to initiate an automatic medrian flip. After the 1 degree is passed the Median flip from the OnStep and Kicks In and start to slew to the center object to the other site of the pier. See als statement of Khalid.
How ever i think we phasing a OnStep bug or missing function it better defined "The command Initiate Medrian Flip"
The LX200 Command Mf# 0
Result 1Object below horizon.#
3Manual Control.#
4Position unreachable.#
Explained Do a meridian flip and slew to the current coordinates.

Today i did a debug of the situation in dry test on iNDI

The question is can this be fixed in the Indi OnStep driver or must we asked first howard to take action to add this function in the OnStep code.
Let me know if this information is oke or you need more you can test this in dry run. Point to a star at the East near the medrian, telescope at west site of the pier. Start imagining session of 120 sec until the star pass the medrian and indi wil initiate flip
Setting in indi
median Flip if HA> 0.02
Settings OnStep
Medrian both site on 1 degree
Let me know how we coordinate to get this function in between the indi OnStep driver or the OnStep firmware and the OnStep Forum
Thanks on forhand
