Add device class in Hue zigbee connectivity sensor

I’d like to have a defined device class in hue zigbee connectivity sensors:

device_class: connectivity
state_class: measurement

This template would then list not connected devices:

            {{ states.sensor
              | selectattr('attributes.device_class', 'defined')
              | selectattr('attributes.device_class', 'in', '[connectivity, signal_strength]')
              | selectattr('attributes.state_class', 'defined')
              | selectattr('attributes.state_class', 'eq', 'measurement')
              | selectattr('state', 'in', '[connectivity_issue, unknown]')
              | map(attribute='entity_id')
              | list }}
