Just tested your idea this morning and it works.
Here is what I see in the terminal :
2016-11-16T06:11:22: startup: indiserver -v indi_asi_wheel
2016-11-16T06:11:22: Driver indi_asi_wheel: pid=4706 rfd=3 wfd=6 efd=7
2016-11-16T06:11:22: listening to port 7624 on fd 4
2016-11-16T06:12:12: Client 0: new arrival from 127.0.0.1:48989 - welcome!
Here is the log in Ekos
2016-11-16T07:12:21 EFW filter is online.
2016-11-16T07:12:12 INDI services started. Connection to remote INDI server is successful. Waiting for devices...
2016-11-16T07:12:12 Connecting to remote INDI server at localhost on port 7624 ...
What can I do now to make it works permanently ?
I tested whith my Atik 314L+ plus the EFW : both works fine together:-)
