Confirming that I just added XHS2-SE with V3 Hub and new app. It originally added as a Thing. In the IDE, changed Type = Tyco Window/Door Sensor. All is good. Shows open/closed, battery, and temperature.
Read all of @JENP post before starting. The first time, I help the tamper switch too long because I was still reading about releasing it during the 4 seconds that the LED is illuminated.
