another example

RSSI HAS statistics, Battery HAS NOT:

sensor:
  - name: 'RSSI'
    entity_category: diagnostic
    platform: ble_client
    ble_client_id: ble_id
    type: rssi
    update_interval: '5s'

  - name: 'Battery'
    device_class: 'battery'
    unit_of_measurement: '%'
    platform: ble_client
    ble_client_id: ble_id
    type: characteristic
    service_uuid: '00000001-$uuid_base'
    characteristic_uuid: '00000041-$uuid_base'
    lambda: return (x[1]*0x100 + x[0]);
    notify: true

It looks like ble_client sensors don't have a state_class by default, since they could be returning any kind of information. You can try adding the appropriate state class explicitly:

 sensor:
   - name: 'RSSI'
     entity_category: diagnostic
     platform: ble_client
     ble_client_id: ble_id
     type: rssi
     update_interval: '5s'

   - name: 'Battery'
     device_class: 'battery'
+    state_class: measurement
     unit_of_measurement: '%'
     platform: ble_client
     ble_client_id: ble_id
     type: characteristic
     service_uuid: '00000001-$uuid_base'
     characteristic_uuid: '00000041-$uuid_base'
     lambda: return (x[1]*0x100 + x[0]);
     notify: true

Indeed, adding state_class: measurement to all these sensors make statistics works. Thank you, @DAVe3283!

I believe https://esphome.io/components/sensor/xiaomi_miscale should be updated before closing this issue.
