Release with the issue: 1.10 & 1.2.0

Last working release (if known): None

Browser and Operating System: Multiple systems/browsers including Android Companion App

Description of problem:

The precision set for my Max UV Index (see screenshots) gets ignored by the UV index card. I have rounded the entity but it still shows on the card, HA itself shows it rounded to 1 decimal (as configured).

@WoBBeLnl the card doesn't manipulate the entity, it display what it receives.
How do you set the precision on the entity?
Do you set a new entity?
What value do you get when viewing the entity in the developer tools --> states?

How do you set the precision on the entity?

• I've set it via Settings -> Devices & Services -> Entities -> click on entity -> change entity -> set precision (see screenshot)

Do you set a new entity?

• No, I've set the precision for the "Max UV Index". This entity is added/updated by the "OpenUV" integration.

What value do you get when viewing the entity in the developer tools --> states?

• It shows the exact state, ignoring my display precision setting. (see screenshot)

I've added a few screenshots chaning my HA to English.

Not sure how a addon works, but with templating you can choose to use the rounding.

@WoBBeLnl thank you will try and have a look :)

@WoBBeLnl I had a look and here are my findings:
I installed the OpenUV integration and added precision to the Max UV Index

Then added some debug to the code and this is what I get back from the entity:

As you can see, the precision value is not returned :( and I haven't got a way to get this value.

Ah thats a bummer. HA is not providing, thats a bummer.
