Can I wake from sleep without mqtt?

Thanks for the assistance. Yes, I know how sleep works- I’ve been using it on Arduino projects for years. What confuses me is yaml.

Your code is one of the multitude of things I’ve tried, but when I try to toggle the entity: input_button.prevent_deep_sleep, the state becomes the date and time??

Also, I want to have eyes into my device yaml execution, so I tried using logger.log, but I can’t even get that to work. (See: Can anyone tell me why I am not seeing "Hello World" in my log file?).

Since I can’t even get logger.log to work, today I plan to add some LEDs to unused pins on the Wemos as state indicators.
