I installed a ST hub about the time Samsung took over. It is still in use. The house is wired for Z-wave and uses Alexa -- most things work, most of the time. HOWEVER, I never liked the idea of needing the cloud for scenes to work. If you have unstable internet, this setup stinks. I installed Vera for a friend in the country last year. It works OK, but could be better. LUUA is not really intuitive.
My gripe with ST is they changed the set up so that you MUST have a Samsung ID/Account and it seems now you must use a phone app to do the developing. Really? I am older and don't want to, nor will I, use a phone to program scenes. I like my computer with multiple screens.
Now, one of my ST scenes has failed and I need to fix it. But, can't get around the crap. So, it is time to look for a replacement hub environment.
