Save Notification in File | Home Assistant | Page 1

Hello, can anyone help me? I need an automation that saves my sensor "sensor.tasmota_mt681_total_in_kwh" (REFERENCE) and my sensor "sensor.tasmota_mt681_total_out_kwh" (FEED) to a stromverbrauch.csv file every day at 11:59 PM. It just doesn't want to work.

My code is:

alias: "Speicherung Energieverbrauchswerte"
trigger:
  - platform: time
    at: "23:59:00"
action:
  - service: notify.notify
    data:
  - service: file.write
    data:
      path: "/config/www/excel/stromverbrauch.csv"
      content: >
        {{ now().strftime('%Y-%m-%d %H:%M:%S') }}, {{ states('sensor.tasmota_mt681_total_in_kwh') }}, {{ states('sensor.tasmota_mt681_total_out_kwh') }}
mode: single
