SONOFF's $22.90 door sensor runs Matter over Thread or Zigbee, and its tamper alert needs Zigbee
SONOFF started selling the SenseGuard DW Gen3 (SNZT-04P) on November 10: a battery door and window sensor that joins Matter controllers over Thread or pairs with a Zigbee hub. In Thread mode every platform gets open and closed, Alexa misses the battery level, no platform gets the tamper alert, and only Home Assistant can update its firmware over Matter.
