Telegram Chatbot

Does anyone have a CURRENT working example of a Telegram Chatbot? I have found the current example (for the waste/recycling reminder) isn’t working - seems to be broken in a couple of ways.

Thank you!

My telegram bot ist working without problems:

telegram_bot:
  - platform: polling
    api_key: !secret telegram_apikey
    parse_mode: html
    allowed_chat_ids:
      - !secret telegram_chatid

notify:
  - platform: telegram
    name: Telegram
    chat_id: !secret telegram_chatid

automation:
  - alias: "Update verfügbar"
    initial_state: true
    trigger:
      - platform: state
        entity_id: sensor.hass_current_version
    condition:
      - condition: template
        value_template: >-
          {% if states.sensor.hass_current_version.state == None or states.sensor.hass_installed_version.state == None %}
            False
          {% elif is_state("sensor.hass_current_version", "unavailable") == True %}
            False
          {% else %}
            {{ states.sensor.hass_current_version.state != states.sensor.hass_installed_version.state }}
          {% endif %}
    action:
      service: notify.telegram
      data_template:
        title: 'Neue Version'
        message: "Home Assistant {{ states.sensor.hass_current_version.state }} ist jetzt verfügbar."
