Wallpanel battery attributes help

I just installed wallpanel and I am really impressed on the performance.
Anyway, I have setup MQTT and I am trying to figure how to show the attributes of the battery status.

When I subscribe to the topic

$ mosquitto_sub -v -p 1883 -t "home/devices/entrance/lenovotab/sensor/battery"
home/devices/entrance/lenovotab/sensor/battery {"value":100,"unit":"%","charging":true,"acPlugged":true,"usbPlugged":false}

But I only get this in the states panel:

Is it possible to show the rest of the info into the attributes?
this is my sensors.yaml

- platform: mqtt
  name: 'Lenovo Tab battery status'
  state_topic: 'home/devices/entrance/lenovotab/sensor/battery'
  device_class: battery
  unit_of_measurement: "%"
  value_template: '{{ value_json.value }}'
