ESP32 have hall sensor built in which ESP8266 did not have. It can be used as door sensor without using any external component specially with ESPNow as low power sensor. It will be even better if hall sensor shut down power to ESP32 when door is closed. When door opens it could power up the ESP32 and it send message saying door is open every few seconds controlled by deepsleep via ESPNow protocol.
Maybe this one can be shared with the touch input suggested in the other issue.
It does need similar parameters and it is also an input-only device.
Both (Hall sensor and touch input) do give some "analog" output, which can also be used for some use cases. So maybe you may also add a setting to either output a discrete value (0/1) or a value scaled from 0..N (scaled to a set range, taking threshold and upper/lower limit into account.
Experimental Hall sensor plugin added in commit 5bb2747 Although i do not know how do you plan to use it, my ESP32 did not return any usable readings, when i moved it near a magnet...
