16 motors / functions using the powered up app not easily possible? in LEGO Technic, Mindstorms, Model Team and Scale Modeling Posted April 19, 2021 · Edited April 19, 2021 by Technic Builder 4 hours ago, Andman said: One of my upcoming MOCs is nearly maxing out the 16 Ports. I had no problems connecting and using the hubs. @Gimmick already posted the code block, which enables you to choose the hub and the specific port. The ID can be from 1 to 4. Hub ID 1 is assigned to the first hub in your connection list. Note that you can change the order of the hubs. So the ID is not bound to the first connected hub. The ports are self-explanatory: just choose A, B, C or D. Just in case you don't know it: Have a look at the guide from @kbalage. With regards to the documentation: Please contact TLG and complain about the missing documentation. I did and the more complain the earlier they might publish one. This guide is the only one I got from them... after asking twice. Will you be controlling your moc with a custom control layout you made in the powered up app, or via powered up controllers or some other means? Or maybe the more relevant question would be have you already controlled more than 1 hub at a time via a custom control layout made in the powered up app?
