radio button array

---

I would like to build an array of three buttons 0,1,2 which acts as radio buttons.

I tried to realize this with ButtonsDevice but I didn’t found how to declare it as radio buttons, think this is the wrong way.

When I press one of thoses buttons it becomes highlighted. When I click on another one this one becomes highlighted and the first one goes back to neutral state. That’s OK. The state of the button array can be retrieved with $myButtons.button, also OK.
But on ButtonsDevice the state is not saved, when I restart pimatic and the highlighting also disappear when I moving around into the UI.

{
      "id": "myButtons",
      "name": "myButtons",
      "class": "ButtonsDevice"
      "buttons": [
        {
          "id": "0",
          "text": "L0"
        },
        {
          "id": "1",
          "text": "L1"
        },
        {
          "id": "2",
          "text": "L2"
        }
      ],
    }

Can someone help, please.

@Heizelmann i dont think it is possible. Maybe you should file this is a future request. It would be nice to use states with buttons

will move this to the feature requests since it is not possible yet.

A way to get around this is by using 3 rules and a variable.
When you click a button a rule sets some variable “button_clicked=1”.
Variable values are saved over sessions.
When you restart pimatic you can use a rule like “when pimatic is starting then if button_clicked =1 …, if button_clicked=2…”

it is not very elegant but it will work.

Thanks a lot. To everyone, please upvote this feature to get it implemented soon.

@Harry-van-der-Wolf there is just no option to highlight an active button… I dont see how your method would work unless you know a rule to highlight a button?

I don’t know either how to highlight a button, but I thought the device state was more important than the color.

And yes: a radio buttons device would be the only real solution.

In my opinion a radio button group is a basic must-have feature. Hope some devoloper can implement it soon.
