We can’t really help without seeing the configuration you have used to implement this. Share the config and format it correctly for the forum. https://community.home-assistant.io/t/how-to-help-us-help-you-or-how-to-ask-a-good-question/114371#oneone-format-it-properly-16
Also: paragraphs and punctuation dude. Use them. Reading your stream of consciousness was a chore.
