Message malformed: Service esphome.esp-buzzer_unit_keep_buzzer does not match format

Hi and welcome to the forum. Two things that will help us answer your question:

  1. Read the category topics before posting and select the most appropriate one. I have already done this for you this time.

  2. Please don’t paste pictures of text. And for text that you do copy and paste please format it correctly. See point 11 here and then edit your post.
