Viessmann Optolink ESPHome

[CajonCP4]

Hi, I don't know exactly where to post my issue, but maybe this is the right place. My goal is to read the switching times.

In the documentation "https://deploy-preview-2737--esphome.netlify.app/components/optolink.html" it says to implement like this:

text_sensor:

• platform: optolink
  name: Heating schedule Monday
  type: DAY_SCHEDULE
  day_of_week: MONDAY
  address: 0x2000
  bytes: 56

but I receive this as an error

========================= [FAILED] Took 19.34 seconds =========================" I tried the normal text component as well:

text:

• platform: optolink
  name: Heating schedule Monday
  type: DAY_SCHEDULE
  day_of_week: MONDAY
  address: 0x2000
  bytes: 56
  mod: TEXT

and I tried to put " whereever strings where needed, but no success. Thanks for helping! And big thanks for the time that has already been given to the project.
