How to display additional zigbee value as separate entity?

Configuration
1

Hello, I have following zigbee2mqtt device. I see Voltage below, but it is not listed as separate entity. I would like to add that voltage as separate entity to see history graph. Is that possible?

You can just create a template sensor from the attribute. :grin:

Thank you but I cannot get the configuration right. This gives TemplateSyntaxError: expected name or number:

sensor:
  - platform: template
    sensors:
      0x60a423fffe138d2b_battery:
        value_template: "{{ state_attr("sensor.0x60a423fffe138d2b_battery"."voltage") }}"

the message from mqtt is following:
