I've checked quickly "MCT-370 SMA" Visonic contact sensor support on Zigbee2MQTT and there is no temperature reporting for this particular model... only contact state is used. At the same time, the temperature reporting cluster 0x0402 is advertised during the device discovery process in Z2M, same as shown on your screenshot, which is rather strange. Could be simply a bug in the device firmware?
Visonic models 'MCT-340 E' and 'MCT-340 SMA' support temperature and battery percentage reporting and configuration.
