Last_reported updates only when last_changed updates

Configuration
1

I have added line template: !include templates.yaml to /homeassistant/configuration.yaml and created the file templates.yaml.

My template sensor is

- sensor:
  - name: "Tuya last reported"
    unique_id: sensor.tuya_last_reported
    icon: mdi:trending-up
    state: >-
      {% set sensorIn = "tuya_01_tz3000_fie1dpkm_ts0201_temperature" %}
      {% set lastReportDate = states.sensor[sensorIn].last_reported | string %}
      {% set lastReportChangedDate = states.sensor[sensorIn].last_changed | string %}
      {{lastReportDate}}
      {{lastReportChangedDate}}

lastReportDate and lastReportChangedDate are always the same. I have enabled debug mode in ZHA and I can see from /homeassistant/home-assistant.log that my sensor is sending rerorts.

If I open Developer tools and then States and choose any sensor, only last update and last changed time is shown.

If I paste this code in Templates in Developer page. Last_report and last_update get different values but not is template sensor.

{% set sensorIn = "tuya_01_tz3000_fie1dpkm_ts0201_temperature" %}
{% set lastReportDate = states.sensor[sensorIn].last_reported | string %}
{% set lastReportChangedDate = states.sensor[sensorIn].last_changed | string %}
{{lastReportDate}}
{{lastReportChangedDate}}

The template sensor is only triggering on change.

But why last_reported will not change when sensor sends measurements if change is less than 0.1 C?

state.last_reported Time the state was written to the state machine in UTC time. This timestamp is updated regardless of any change to the state or a state attribute
