Yes, it is. You must just put the right diseqc commands, which must be
send to move the rotor, into your diseqc.conf. Then when you switch to a
channel of another satellite these commands will be sent.

What's wrong with the rotor plugin?

The rotor plugin should supply all diseqc-command you need for a rotor.
(Drive East/West, Drive Steps East/West, Goto/Store Position,
Recalculate Position, GotoX, Set East/West Limit, Limits On/Off)

No, there is no feedback from the rotor, so the plugin can't know.

Does the rotor move if you e.g say "Drive East". When not, please look
in your log-file. When there are errors like "ERROR: Operation not
permitted" then you have to apply the Fd_Frontend patch (you find the
diff-file in the patches directory of rotor-0.1.0) and recompile the

Your rotor must be directed to True South. Otherwise it won't work for
satellites which are further in eastern and western direction.
Of course your rotor have not to rotate 13 degrees, when your site
longitude is e.g 12° East, then you only must move to 1°.
To adjust all stored position you must find one satellite and then send
the recalculate command.
The other possibility is to use the Goto X command. For this you only
have to enter site longitude and lattitude in the setup menu of the
rotor plugin. Then you can select a satellite and press OK and the rotor
should then move to the right position.

All needed diseqc commands are explained here:
