Insanely cheap price for the ADT SmartThings Door & Window Sensors and the ADT Keychain Remote. Each are $5 at Best Buy. These ONLY work with ADT SmartThings hub. I guess I’ll be stocking up personally but I don’t know if this is a sign that these will be discontinued or replaced soon with CES 2019 right around the corner:
