Rest sensors don't keep long-term statistics

Hi All,

I have some rest sensors collecting weather data from the API of the local weather website. Unfortunately, the long-term statistics are not kept after the automatic purge. Yesterday, I figured out they didn’t have the state_class, so I added it for each of them, but the night automatic purge removed the data from the recorder, and the long-term statistics are still not kept.

Sensor example:

  sensor:
    - name: "Temperature Piastów"
      value_template: "{{ value_json['data']['temperature']['current'] | round(2) }}"
      state_class: measurement
      device_class: temperature
      unit_of_measurement: "°C"
      unique_id: restful_temperature_piastow

The sensors are on the statistics card, but the history graph does not show data older than 10 days. The zigbee2mqtt sensor’s long-term statistics are normally visible in the history graphs.

Your correction will only be visible after 10 days. Long-term statistics are not generated from old data, but in real-time.

OK, thanks. Now I know how it works and I have to wait.
