Change default display precision

I just updated to the latest version of HA(2025.6.1) and all of a sudden all of my voltage sensors have defaulted to hiding the decimal point value. Now I searched and understand that I can change the display precision for a specific sensor entity in the entity’s settings: “Display Precision” option in the entity’s configuration dialog.

The option selected is Default (3) and I can change it to 3.45.

My question is, how can I change this Default to display the rest of the values for all my battery cell voltages, I have over 30 entities and I would like to avoid having to go 1 by 1 if there is a way to change the Default.

Hello domescape,
Welcome to the Home Assistant Forum!

Precision is set per entity . Open the entity screen and change it.

I just noticed all my voltage sensors defaulted to zero decimal places too.

Hm… same here… not another “smart” decision from dev’s, isn’t it? Wasn’t entity names mess enough? I can’t stop myself wondering that someone has started to play a fun with users… i mean - i didn’t even finish correcting my hundreds of (forcefully) renamed entities and now i’m stuck with dozens of voltages, too?

I’ve also created an issue on GitHub for the batmon addon using your issue as a template, thank you.
