Display countdown from a date/time that's from a washer/dryer.

My LG washer and dryer generates a date/time for when the laundry will be done. Is there a way to create a countdown using the the date/time provided? I want to display the countdown on my dashboard. The date/time does change a few times before completion.

Just out of curiosity, does your screenshot show one load being washed? The durations seem a bit weird. It was started at 11:04 and was going to take an hour. Thirty minutes later, it still has an hour remaining. Or did you change wash settings during that time?

Next, how are you wanting to see the countdown? If you're looking for a true, by the second kind of countdown, that might be a bit difficult. By the minute probably wouldn't be too hard to do. Also, do you have other entities available that let you know if it is currently washing or has finished. Those might come in handy.

Try a tile card with this sensor as its entity. If its device class is duration, the tile card will automatically render it as a human readable countdown. I have one that's displaying my LG washer's remaining time in HH:MM.

It was one wash that the time kept updating as the wash was going on.

I'm wanting to use a Bubble Card that shows the current status of the washer (running, rinsing, spinning, and finished) and the time remining. I'm good on it being minutes. I have an announcement that plays on our Home Pod that happens when the wash is done.

I've tried that but it shows a date and time of when it will be done and not a countdown.

Ok, then what you can do is to create a template sensor of device class duration to parse the raw state of the LG sensor into the correct device class.
