A great value and compact door/window sensor. It sends separate open and close commands. It also has manually pressable button on the front, and a tamper switch on the back but, disappointingly, both the manual button and the tamper switch just send the open command rather than unique commands of their own. Powered by an included CR2032, and even has an on/off switch.

I have tested with Sonoff Rf Bridge it is detecting and triggered. But I didn't receive any trigger notification to eWeLink app.
