ChatGPT integration - bot repeats itself

Configuration
1

Hi,

I let ChatGPT create a ‚good morning‘ message and send it to me via Telegram. The process overall works. But ChatGPT repeats itself almost every day.
My question: how can I teach the bot not to repeat itself.

My config as follows:

OpenAI Conversation configured basically as per default instructions provided here.
Furthermore, I created an automation to use ChatGPT response as follows:

alias: "‘Good morning‘ telegram_to_all message"
description: ""
trigger:
  - platform: time
    at: "04:30:00"
condition: []
action:
  - service: conversation.process
    data:
      agent_id: 289ccb...[...]
      text: >-
        Write a personal "good morning" message mentioning the weather for the
        day, sun rise and sun set details at my current location, which is {{
        state_attr('person.user1', 'latitude') }}, {{
        state_attr('person.user1', 'longitude') }}.

        Also, tell some interesting "fun fact". Do not repeat the fun facts from previous days.
    response_variable: chatgpt_response
  - service: notify.telegram_to_me
    data:
      message: "{{ chatgpt_response.response.speech.plain.speech }}"
mode: single

Any suggestions?

Thanks!
