Lovelace Restriction Card - Client-side Security

Because there is no visual editor available for this custom card, as per the first words of the error message…

It’s nothing to worry about, as per the last words of the error message :wink:

possible to lock a switch in a glance card?

this here dont work

type: glance
title: Schlafzimmer
entities:
  - entity: switch.on_off_plug_in_unit_4
    type: 'custom:restriction-card'
    row: true
    name: Licht
    icon: 'mdi:lightbulb'
    tap_action:
      action: toggle
state_color: true
show_icon: true
show_name: true
show_state: true

trying to 'restrict my garage door, as per suggestion of Thomas, I started with the core row on an entity cover:

      - type: entities
        entities:
          - type: custom:restriction-card
            row: true
            condition:
              entity: cover.garage_deur
              value: closed
            restrictions:
              confirm:
                text: 'Garagedeur openen?'
              pin:
                text: 'Voer Pincode in:'
                code: !secret tahoma_secret
                max_retries: 3
                max_retries_delay: 30
            card:
              entity: cover.garage_deur
              secondary_info: last_changed

however, just to be sure, please let me ask: this makes the pin text appear first, and, after successfully entering the code, makes the confirm text appear. Which is the other way round from what I expected :wink:

is this as per design, or did I make a user error?

in the repo, there’s an ‘Invalid pin entered’ dialogue video, but no instruction how to do that… Would anyone know which confirmation text that is? Right now, with the above code, simply nothing happens except for the icon to flash.

the last_changed isnt displayed on the entity. Since there is plenty space, that can’t be it. Does the lock overlay prevent displaying secondary_info? Would be really appreciated if this could be done.

Though I realize we can set the position of the icon in a theme, and I do use the relative setting to do so, I need the lock to be on a different spot using the cover, than when using eg a single toggle.

Would it be possible to do so?

thanks for having a look.

btw, I also added the restriction on a core entity card, but that seems futile, because clicking that simply opens the more-info, where the lock is not displayed?

The design is to use one restriction. The example is just for show. Sounds pretty unfriendly to put so many clicks in the way. The the order is what it is, I have no intention of changing it.

That was removed

No, it doesn’t. You are not using the correct option; last-changed

I will not be changing it

I’m not following what you’re saying here

yes! thank you for spotting that…

I tried the lock on

      - type: entity
        entity: cover.garage_deur

but it didnt work, probably because of a wrong config, didnt see an error though, just the more info clicking the entity. Using:

      - type: custom:restriction-card
        <<: *restrict
        card:
          type: entity
          entity: cover.garage_deur

now makes it happen.

was only asking, so cool, not an issue at all. thanks for your time and effort replying in such short notice!

Good day!
Started testing this card.

Questions:

  1. Regarding "restrictions::hide".
    Here is a card:
type: vertical-stack
cards:
  - type: entities
    entities:
      - entity: sun.sun
      - type: 'custom:restriction-card'
        restrictions:
          hide:
            condition:
              entity: input_boolean.test_boolean_4
              operator: ==
              value: 'on'
        action: hold
        row: true
        card:
          entity: sun.sun
      - type: 'custom:restriction-card'
        action: hold
        duration: 10
        row: true
        card:
          entity: sun.sun
  - type: entities
    entities:
      - entity: input_boolean.test_boolean_4
        name: hide

There are 3 entity rows:

  • 1st - not restricted
  • 2nd - restricted with the "hide" option;
  • 3nd - restricted.

If the toggle button ("input_boolean.test_boolean_4") is ON then the 2nd row is supposed to be hidden.
But it happens only after manual refresh (F5):

Is it a bug?


  1. The restriction card is supposed to be used in different places of HA GUI.
    That is why it is better to have a PIN defined in one place.
    I tried to specify smth like "pin: !secret my_pin" (no success).
    What is the best practice of storing the PIN ?
    The same question about user id.

Of course, there is a walkaround - we can create a "decluttering-card" template for this:

  decl_restriction_card_row:
    default:
      - VALUE_ROW: false
    card:
      type: 'custom:restriction-card'
      restrictions:
        pin:
          code: 1234
          text: Введите PIN для разблокировки
          retry_delay: 3
          max_retries: 3
          max_retries_delay: 10
      action: hold
      duration: 10
      row: '[[VALUE_ROW]]'
      card: '[[CARD_OR_ROW]]'

The idea is to define a restriction-card with required settings (presumably same settings for all HA views) in ONE place (with specified pin & user id data) and then use this template in all views.
How to use the template for a row:

type: entities
entities:
  - type: 'custom:decluttering-card'
    template: decl_restriction_card_row
    variables:
      - VALUE_ROW: true
      - CARD_OR_ROW:
          entity: sun.sun

  1. Yeah, I see the bug right away in restriction-card/restriction-card.ts at 1f56db9270450cb717c4e2819a10c411b77f6a64 · iantrich/restriction-card · GitHub and I’m really surprised no one has came across it till now :slight_smile:
  2. I do not have a recommendation on storing your pin.

Hello Ian, thank you very much for your card and a quick reply!

  1. Great that you found a reason of that behaviour. Looking forward for an update, will test it when released. Probably this “hide” option could be useful.
    Every time I start learning a new card, I am usually trying to test it with some test cases (may find some new issues).

  2. Regarding PIN - basically this is not about a privacy (“someone can steal my PIN !!!”), this is about reducing a code (“define it in one place, call it from many places”).
    So I will proceed (and recommend it to other people) with decluttering-card. Together these two cards will help a lot.

Some card-mod styling (including for "decluttering-card") is described here.

How do change the placement of the lock, or what color it has?
I have this code:

type: custom:restriction-card
restrictions:
  confirm:
    text: Sikker??
card:
  type: entities
  entities:
    - switch.05301030f4cfa2341de5
  state_color: true

And it looks like this:

But no matter where I put lines like:
restriction-regular-lock-color
or
restriction-lock-margin-left

Nothing seems to change.

So what am I doing wrong?

Thanks.

The theming options, surprisingly enough, go in your theme. Not the card.

I’m assuming this is an answer to me.
And yes, this is the question.
I don’t understand where to put / configure the Theme Variables.
I haven’t found one example that can tell me this.

Thanks for answering, but these are not really answers at all.
First, I have never heard of themes before, and therefore I had no configuration for it.
And how is it logical to assume that configuration that applies to this specific card only goes into a global configuration file?

It is ok not to answer questions. Better that, than to “answer” questions.

I had a feeling that you may not be aware of themes after you ignored the first link I made to help you that linked to this (emphasis mine):

The following variables are available and can be set in your theme to change the appearance of the lock. Can be specified by color name, hexadecimal, rgb, rgba, hsl, hsla, basically anything supported by CSS.

So I linked to the Home Assistant themes document for you. Where you could read all about them.

Apologies if that was not clear enough for you.

Since you apparently have a card like this configured, why don’t you just copy / paste a few lines from that config, and this would have been answered a long time ago.

Thanks.

Because as I said many times already it does not go in the card, it goes in your theme. And as my theme makes extensive use of card mod it would just be confusing. But sure, here you go: Day and Night - #29 by tom_l

I just discovered by accident that this card seems to have a bug. If I hover my mouse slightly above the locked entity switch I get control.

Has anyone else noticed this?

Yeah I see that too. If you get it just on the edge of the touch radius:

Here´s the issue you created :smiley:
