Thermostat Card does not show target temperature and operating mode (it does not change the color) with climate.nest

Hi, I’ve a Nest thermostat configured in my Home Assistant. I configured the thermostat card as follows:

      - type: custom:thermostat-card
        title: Nest
        entity: climate.nest
        chevron_size: 100
        highlight_tap: true
        hvac:
          states:
            'Off': 'off'
            'Eco': 'eco'
            'Heating': 'heat'
          attribute: operation_mode

But the thermostat card does not show the target temperature. Furthermore when I increase or decrease the target temperature, by tapping on the widget, it starts always from 0 degrees.

Neither the operating mode is showed by changing color.

I’ve seen that the attributes of climate.nest are:

operation_list: off,heat,eco
away_mode: on
supported_features: 1153
max_temp: 32
friendly_name: Entryway (Termostato)
operation_mode: heat
current_temperature: 23.5
temperature: null
min_temp: 9

The other “attributes” are sensor or bynary_sensor like:

binary_sensor.entryway_thermostat_termostato_has_leaf
sensor.entryway_thermostat_termostato_target
sensor.entryway_thermostat_termostato_hvac_state

this is my widget when the nest is heating:

I will add it as an enhancement.
