Besmart custom_components climate

Hello, is possible have the battery_state info?

Like in the past was for example:

  besmart_battery_state:
    friendly_name: "battery state"
    device_class: battery
    value_template: "{{ state_attr('climate.termostato_sala_salotto_thermostat', 'battery_state') == '1' }}"
    icon_template: mdi:battery
