I never had issues with ST and now Ring with the locks. I could not get them to pair with HE.
The way I got around the issues I was having with my Schlage locks and HE was to move the locks to Ring and then use the Unofficial Ring Integration app to control them. I have had zero issues since doing that. If you are in the market for an alarm and have the stomach to use Ring this may be something to try. The cost of the basic Ring setup and a new Schlage lock are comparable. You won't need a Ring subscription to use this setup. If Ring ever makes changes that render the Unofficial Ring Integration inoperable I guess I'll be SOL.
I'm not here to debate whether HE or Schlage is the issue. I'm just offering an option that worked in my environment.
