There are some old discussions on DIY patio door locks that might also be of interest. They discuss one mortise electronic strike in some detail. It still has to be wired to something that’s controllable by smartthings, but they discuss that, too. Just don’t get too excited about the Padiolok device discussed in that thread–it didn’t meet its funding targets and doesn’t look like it will come to market for a long time, if at all.
