WXKG11LM switch attributes via zigbee2mqtt

Configuration
1

I have a number of these button switches.
In zigbee2mqtt I can see for example:

{
    "battery": 100,
    "device_temperature": 35,
    "linkquality": 87,
    "power_outage_count": 186,
    "temperature": 28,
    "voltage": 3175
}

In MQTT Device Info for the entity I see, under diagnostic, three attributes:
Battery
Power Outage Count
Temperature

Also Link Quality & Voltage are shown as disabled entities

The temperature shown in HA is the ‘device temperature’, ie 35.
How can I get the ‘temperature’, ie 28
