For anyone considering buying a Sofabaton X2, I have to say that this is finally a worthy replacement for Harmony and URC remotes. There are a couple of minor, mostly software, issues, but no showstoppers for me (unlike the X1).
I provided some feedback to the Sofabaton team via their forum, and if any of those items are on your wish list, perhaps pop over there and let them know - as they say, the squeaky wheel gets the grease.

So far I've found the software improvements (App and Remote) to be a very large step forward too and I only have a few items I'd like to see improved:
Adding an additional device to an existing activity forgets your configured inputs for the existing devices - please fix!
Why do we need to add a device to an activity so we can add buttons to the favorites?
- eg I just added my Hubitat Hub for IP control of lighting etc, and now I need to add it to 8 different activities before I can add lighting scenes to the favorites for each. Just seems very unnecessary for this scenario.
It would be nice if we could copy multiple favorites buttons from one activity to another
- eg I have a set of AVR audio presets and Lighting scenes I want available on all 8 activities and setting up each one for every activity is a chore. On my old URC remotes I can just clone the whole favs page.
Please allow macros to be called from startup / shutdown sequences.
- It would also be nice if we could clone existing steps in macros. eg if the down button needs to be pressed 5 times, this gets tedious to add manually.
Minor bug - sometimes when I've spent a bunch of time setting up favs etc, my X2 remote loses all the activities I was working on until I Sync it. Perhaps syncing after every little change during setup is too much?
