Samsung 2017 series 6 tv on/off virtual switch in IDE?

Certainly in conjunction! In fact i only have harmony do what st can’t do, so I’ll make routines that have a bunch of things changing in ST and also include a harmony activity like turn on the tv, watch Netflix etc.

@prtmkr2010 check out Lost TV Connection with Smartthings where they discuss the lost TV connection to ST in excruciating detail.
