You have the newer Mobile Throttle. I have the older one and all it had was the ESU app. I had to strip a lot of unnecessary stuff off it to make it run faster, then install Engine Driver. The one you have is a major improvement.
ESU has since made several changes to the firmware including adding the server function to the command station to accept signals from both WII Throttle and Engine Driver. Being native to the command station, they now work with or without JMRI.
Just put the command station on your home network and sign in to the same network with your throttle.
I have some older friends who only work with Digitrax. They struggled to learn the Mobile Throttle or WII Throttle, so I bought an L-Net converter, hooked to my command station, installed a couple of UP-5's and now they bring their own throttles and are happy.
If you haven't yet, I recommend joining the ESU forum on their website. A lot the posts refer to things we don't have in the US and you have to take advantage of Google translate to read some. You have to own an ESU product and provide the serial number to join, but it's worth it.
