I got into ST about a year or so before samsung acquired them. Amazing ecosystem at the time and the ST community was great. I even taught my self groovy, so I could write my own device handlers. Then it went down hill couple of years after the acquisition. I still have my gen 2 ST hub and have been slowly trying to pivot towards HA. How easy is it to integrate ST into HA? I have a bunch older zwave wall switches and few other sensors that are tied into ST. But I really hate the ST app.
