Same issue here, apparently, I only noticed it because "Energy Generated" (in contrast to "Power Generated", but I guess this also was unavailable) returns wrong values respectively the same value over and over again.

Here the "response time":

Maybe, the integration could add a repair error to yield up in such a case, at least?

Otherwise, here is a possible workaround (automation) to send a notification, currently:

alias: FoxESS Crawling Error Warning
description: ""
triggers:
  - trigger: state
    entity_id:
      - sensor.foxess_response_time
    to:
      - unavailable
      - unknown
    for:
      hours: 0
      minutes: 1
      seconds: 0
conditions: []
actions:
  - action: notify.send_message
    metadata: {}
    data:
      message: >-

        Please check solar statistics.
