Energy panel - None value in energy sensor

I have a smartplug connected by zigbee using mqtt but my problem is with “energy” attribute.
this is a resume atributes
power 25
current 0.21
voltage 224
energy N/A

and this is a full attributes’s state:

state_class: total_increasing
child_lock: LOCK
current: 0.21
energy: null
indicator_mode: null
linkquality: 255
power: 25
power_outage_memory: ‘on’
state: null
update_available: null
voltage: 224
unit_of_measurement: kWh
device_class: energy
friendly_name: Smart-Plug-01-[Servidor] energy

and here is power energy panel

Exists any way to save the accumulated energy or solve my problem ?
