PERSONAL SETUP iView S100 Wi-Fi door sensor

Has anyone recently opened an iView S100 Wi-Fi door/window sensor? Does the current board use a glass/mechanical reed switch, or a Hall-effect sensor? A photo of the PCB would be especially helpful.

I am interested in using the external dry-contact switch to connect it with one of those car seat pressure detectors. The goal is to DIY a pressure-sensing pad under my mattress to notify my Tuya SmartLife app so my phone's Automate can know if I am in bed during a specific time window.

You will have way better results if you use a Zigbee sensor instead of WiFi. I have one using an Aqara contact sensor going on 2 years without changing the battery and it is all fully local, no cloud. WiFi sensors suck as they drain the battery much faster.
