External integration - Wallbox

Hello,

I am currently developing an external integration to control a Wallbox.

Here is the GitHub → GitHub - EchoPouet/gladys-wallbox: External Gladys Assistant integration for Wallbox EV chargers. · GitHub

I am currently facing a limitation for displaying and modifying the value on the homepage.

Here is an image to illustrate my problem.

My problem is as follows: I cannot modify the last field with a step of 0.0001, which is the price of electricity. The step is limited to one.

Should I use something else to modify this value?
