The u2 does not have the ability for macros to set the active device in the remote. The way I got around this personally which may not work for everyone but works for me is to have macros programmed to the Input select button on every device, I scroll to what I want, hit select source and my gear does its dance to change I puts and settings, leaving the remote on the device page needed.

find the closest similar model, almost all of the Samsung TVs use the same commands and have the same functions. The IR works better than the Bluetooth in most cases keep that in mind.

With gear in the class of DCS and D'agostino you should consider getting an RTI tech to put in a proper system. Sofabaton is not going to be reliable enough. Nice gear though! I'm a fan of Dans gear and have one of his classic Krell FPB power amps.

I also have an issue editing some entries via the App, some devices work and I can update the buttons or change a macro, but others come up blank and changes made don't apply. I delete and redo the device and again it comes up blank when I try to edit it. This seems to apply to where I have multiple versions of the same device (2x Teac HDB860 DVBT tuners for example) I need two entries for them with slightly different macros configured but the second one always comes up blank when editing? This software is appalling.

You need to implement a way to save the configuration on a remote so that when configuring a new one people can load the backup and have their configuration restored. Imaging having 15 devices all manually learned button by button and having to re-do that because your scrollwheel was playing up ?

Yes they are, but I think they jsut have one person that watches this website and rarely comments anything particularly useful. The X1S is due for release early next year and a firmware update for the U2 was just released a short while ago. I think they are just a tiny branch of a still quite small company so nothing happens particularly quickly.

Most Onkyo receivers use the same IR commands and have done for many years now, try some similar models from around the same year and you will find codes that work, failing that, use the IR learning to copy the commands from the stock remote.

I had no issue controlling a Shield via Bluetooth, however the best functionality comes from using a FLIRC customisable IR receiver, that allows you to map any command to any function or keypress on the receiver, including every key on a keyboard for proper control over apps like kodi, and custom shift/control macros in the receiver for mapping custom functions in android to launch apps etc. All the remote needs to do then is spit out any IR command and the flirc can map it to any complex function.
