After seeing this How to automatically reload integration on a schedule? - #2 by msp1974

I now set up a similar script which you can pass any entity to and it will reload the associated integration. (however I noticed that my problematic integration has a different problem)

alias: Reload Integration for Entity
mode: parallel
fields:
  entity:
    description: Entity whose integration shall be reloaded
    selector:
      entity: {}
    required: true
variables:
  entities: "{{ integration_entities(integration) }}"
sequence:
  - condition: template
    value_template: "{{config_entry_id(entity) != \"\"}}"
  - action: homeassistant.reload_config_entry
    data:
      entry_id: "{{config_entry_id(entity)}}"
