Lovelace Custom Fan Card Example

Any examples of custom Lovelace state cards? Not card cards, but state cards.

Like:
https://developers.home-assistant.io/docs/en/frontend_creating_custom_ui.html

I have something working, but really it is just wrapping around the old style way of doing things. As such, things like override the name doesnā€™t work.

I am not compiling, so Iā€™m not sure I can import things from HA. If I can, I donā€™t know the proper path. So I canā€™t import computeStateName, etc.

This ā€œworksā€ but ignores the name I pass in from ui-lovelace.yaml. Probably because state-info only gets stateObj which doesnā€™t have the correct name in it.

const UNAVAILABLE = 'Unavailable';

I found that if I use hui-generic-entity-row and not state-info, I get closer to what I want. The name override works, but when I click and bring up the more info, it has undefined as the last activated time.

Iā€™ll keep digging and post a complete example when I get it working.

Not sure I 100% understand what youā€™re after, but this is a great reference site for lovelace-ui:
https://home-assistant-lovelace-gallery.netlify.com/#

Update: I figured it out, most of the post below can be ignored.

I had a custom component using the state_card_custom_ui_secondary: state-card-fan-custom. It looks like what I have there, what I consider the ā€œold wayā€, was the cause of the problem. Once I removed that customization, my control, source below, is working as expected.

Figured this out while waiting for a 504 gateway error to go away, anyway, what I was originally going to postā€¦

Original Post:

I am recreating the state-info card for a fan that has l/m/h buttons on the entity card without using the custom_ui stuff (Andrey home-assistant-custom-ui)

Most examples are for the big cards, not the individual entities or state-info.

I got most of it working, including respecting the name specified in the lovelace configuration file:

  - type: entities
    title: Master Bedroom
    show_header_toggle: false
    entities:
      - entity: sensor.wirelesstag_bedroom_master_temperature
        name: Temperature
      - entity: sensor.wirelesstag_bedroom_master_humidity
        name: Humidity
      - entity: fan.master_bedroom_fan
        type: custom:custom-fan-card
        name: Fan
      - entity: light.master_bedroom_light
        name: Light
      - entity: light.master_bedroom_nook
        name: Nook Light

What I donā€™t have, however, is the last changed time in the more info:

2018-09-13%2008_45_41-Home%20Assistant

At some point the future, Iā€™d like to figure out how to override the controls in the more-info dialog, but that is for the future.

Here is the code I have so far for custom:custom-fan-card:

class CustomFanCard extends Polymer.Element {

    static get template() {
        return Polymer.html`
            <style is="custom-style" include="iron-flex iron-flex-alignment"></style>

have you hosted the lovelace fan card code anywhere?

awesome card. :+1:

could you share how you got this working?

resources:
  - url: /local/custom-fan-card.js
    type: js

not sure what iā€™m missing (created the file above using the code shown along with the card referenced):

  - title: Upstairs
    icon: mdi:arrow-up-bold
    id: upstairs
    cards:
      - type: vertical-stack
        cards:
          - type: entities
            show_header_toggle: false
            entities:
              - entity: fan.bedroom_fan
                type: custom:custom-fan-card
                name: Bedroom Fan

not sure what else to try? thanks in advance for any help :smiley:

Looks ok to me.
I used the last src code he published. Also change type js to type: module

After that, in chrome press f12, go to refresh icon right click ā€œEmpty cache and hard reloadā€

I havenā€™t. I might create a repo and post things as I play with them. Iā€™ll let the thread know. What Iā€™m running now is here in this thread so I havenā€™t bothered with repo yet.

Hello, can you explain a little bit more of what you actually did to make this work?

Awesome card.

Big thanks for posting this custom card code, I use lovelace for a control panel and even thought itā€™s a 10inch tablet the icons are to small, this is perfect to make my icons bigger but keep the interface compact.

love lace config

- type: custom:custom-fan-card
  entity: cover.blind_b1_block
  name: Sheer

and I get this, show comparison to normal entitiy garage cover icons

Big thanks again, I how need to modify code to handle all the different shutters, which Iā€™ll have a go at and let you know/ask for help.

What error/issue are you getting? using type: js worked for me

This works well but the only problem is the last fan speed stays selected when you turn the fan off . Seems like the card does not reset the state when the fan is off. You have to choose another fan speed to start it again.

A similar problem was fixed in the old interface --> Fan Control. Has anyone got this working in lovelace?

Hello, I add the ā€œoffā€ button to the card, but seems not working. I click the ā€œOffā€ button is only can trigger the on-tap event, but cannot disable the button. Anything i doing wrong. Please help!!!

Yes, work now. Thanks a lot!!

Iā€™m fairly close to making this work just like the other state_card_custom_fanspeed interface did but Iā€™m stuck on two things:

  1. Does anyone know how the syntax to use logical operators to set the state of a boolean in the code? Iā€™ve tried ā€œ_boolean3: (_boolean1) && (_boolean2)ā€ which gives errors. I tried it without the (). Iā€™ve tried with {}. Iā€™ve tried with {()}. etcā€¦

  2. what is the way to set the background color if the button dynamically with the state of a boolean?

Iā€™ve done searches for every iteration of those search terms I can think of and canā€™t find the answers. Everything Iā€™ve found has been very basic or unrelated to the questions I have. Comprehensive Polymer documentation is pretty hard to find.
