I tried adding the following code to DEVICE_TYPES and was able to read the temperature/humidity data, but the buttons did not work

    0x520B: DeviceEntry(
        name="Temperature/Humidity Sensor",
        model="KS2BB",
    ),

Please post the BLE messages and the encryption key, such that we can check the data.

Here is what I can gather from home assistant bluetooth advertisement monitor.

Linptech KS2 is a Temperature Humidity Sensor that is also a button.

Button Press event:
{"name":"linp.sensor_ht.ks2bb","address":"A4:C1:38:A1:FE:E6","rssi":-82,"manufacturer_data":{},"service_data":{"0000fe95-0000-1000-8000-00805f9b34fb":"58590b52b4e6fea138c1a4308fa80900000de1ebdb"},"service_uuids":[],"source":"A0:B7:65:4D:30:26","connectable":true,"time":1768294087.0960305,"tx_power":null,"raw":"020106181695fe58590b52b4e6fea138c1a4308fa80900000de1ebdb15096c696e702e73656e736f725f68742e6b73326262"}

Temperature event:
