In case you're wondering, YES... I now have my X2 controlling dozens of devices through Home Assistant. The process is a little convoluted (detailed elsewhere on this forum and on the relevant reddit groups) but it DOES work... you can trigger devices and scenes from soft or hard buttons on the X2 to do things in Home Assistant if you work through the process patiently.
So far I have it controlling my most important lights and shades (lutron) via Home Assistant MQTT which was a must-have for me.
I also have some HA actions that I now can trigger via soft buttons on the X2 directly too... which has solved some tricky issues for me as well.
And those HA actions can be put into sequences/macros including startup/shutdown sequences right within the X2 programming app once you have them implemented right.
