I have no experience with the Seluxit since I am in the US and it appears there are only EU versions of that. Whether my issue is unique I don't know. In order to include the tricklestar controller I had to pull the MCV dongle out of my machine and include it by pushing the button. The controller would not include while connected to the machine and sending an add node command. Also, while reading the specs on the Aeon/MCV it said that the dongle was an update controller. While it did not specifically say that it would not work in SUC or SIS, the specs did not say that it could either. Once I received the Tricklestar it specifically said it would work in SUC and when used with the Tricklestar controller it would work in SIS. You just had to make sure that the controller was the second device in the network.
In any case, I did include the Tricklestar controller with the MCV dongle (with the usual remove the dongle, putting it in include mode, and including the Tricklestar controller with it) but could not include any devices with the controller. It has been a couple of weeks since I have tried but I believe I could include a device with the controller but whatever should have happened between the Tricklestar controller and the MCV dongle did not occur. lmce never saw the newly included device.
