How to display an input select with all (or filtered) entities?

[alexslx (Alexandre Leites)]

Hello,

I’m wondering if there is how (by default or custom component) display an input select which enables the lovelace user select an entity.

For example, when you use the “Configure UI” option on the newest versions, you click to edit an entity card there are inputs which you can select the entity ids which will be displayed.

I would like to use a similar input on my lovelace template so I can select on runtime which entity is related to a specific automation for example.

Here’s something that i use for this.

Fill Input select

Hi, I’m trying to make an automation, so when HA starts, it fills an option select with all the entities that belongs to a group. I’m trying with the lights_all group, but it cloud be anyone. The idea is that when I include an entity in this group, it automatically appears (after reboot) in all the input selects that I want . Can anybody help me?
