Lovelace Mini Graph Card

A minimalistic and customizable graph card for Home Assistant Lovelace UI.

The card works with entities from within the sensor & binary_sensor domain and displays the sensors current state as well as a line graph representation of the history.

Preview

Install

HACS (recommended)

This card is available in HACS (Home Assistant Community Store).

HACS is a third party community store and is not included in Home Assistant out of the box.

Open your Home Assistant instance and open a repository inside the Home Assistant Community Store.

Manual install

  • Download and copy mini-graph-card-bundle.js from the latest release into your config/www directory.
  • Add the resource reference as decribed below.

CLI install

  • Move into your config/www directory.
  • Grab mini-graph-card-bundle.js:
$ wget https://github.com/kalkih/mini-graph-card/releases/download/v0.13.0/mini-graph-card-bundle.js
  • Add the resource reference as decribed below.

Add resource reference

If you configure Lovelace via YAML, add a reference to mini-graph-card-bundle.js inside your configuration.yaml:

resources:
    - url: /local/mini-graph-card-bundle.js?v=0.13.0
      type: module

Else, if you prefer the graphical editor, use the menu to add the resource:

  • Make sure, advanced mode is enabled in your user profile (click on your user name to get there)
  • Navigate to Configuration -> Lovelace Dashboards -> Resources Tab. Hit orange (+) icon
  • Enter URL /local/mini-graph-card-bundle.js and select type "JavaScript Module".
(Use /hacsfiles/mini-graph-card/mini-graph-card-bundle.js and select "JavaScript Module" for HACS install)
  • Restart Home Assistant.

Updating

If you have a version older than v0.0.8 installed, please delete the current files and follow the installation instructions again.
  • Find your mini-graph-card-bundle.js file in config/www or wherever you ended up storing it.
  • Replace the local file with the latest one attached in the latest release.
  • Add the new version number to the end of the cards reference url in your ui-lovelace.yaml like below:
resources:
    - url: /local/mini-graph-card-bundle.js?v=0.13.0
      type: module

You may need to empty the browsers cache if you have problems loading the updated card.

| Name | Type | Default | Description | |------|:----:|:-------:|-------------| | entity (required) | string | | Entity id of the sensor. | attribute | string | | Retrieves an attribute or sub-attribute (attr1.attr2...) instead of the state | name | string | | Set a custom display name, defaults to entity's friendly_name. | color | string | | Set a custom color, overrides all other color options including thresholds. | unit | string | | Set a custom unit of measurement, overrides unit set in base config ('' value for an empty unit). | aggregate_func | string | | Override for aggregate function used to calculate point on the graph, avg, median, min, max, first, last, sum. | show_state | boolean | | Display the current state. | showlegendstate | boolean | false | Display the current state as part of the legend. | show_indicator | boolean | | Display a color indicator next to the state. | show_graph | boolean | | Set to false to completely hide the entity in the graph. | show_line | boolean | | Set to false to hide the line. | show_fill | boolean | | Set to false to hide the fill. | show_points | boolean | | Set to false to hide the points. | show_legend | boolean | | Set to false to turn hide from the legend. | stateadaptivecolor | boolean | | Make the color of the state adapt to the entity color. | y_axis | string | | If 'secondary', displays using the secondary y-axis on the right. | fixed_value | boolean | | Set to true to graph the entity's current state as a fixed value instead of graphing its state history. | smoothing | boolean | | Override for a flag indicating whether to make graph line smooth.

entities:
  - sensor.temperature
  - entity: sensor.pressure
    name: Pressure
    show_state: true
  - sensor.humidity

Available show options

All properties are optional.

| Name | Default | Options | Description | |------|:-------:|:-------:|-------------| | name | true | true / false | Display name. | icon | true | true / false | Display icon. | state | true | true / false / last | Display current state. last will show the last graph point's value. | graph | line | line / bar / false | Display option for the graph. If set to bar a maximum of 96 bars will be displayed. | fill | true | true / false / fade | Display the line graph fill. | points | hover | true / false / hover | Display graph data points. | legend | true | true / false | Display the graph legend (only shown when graph contains multiple entities). | average | false | true / false | Display average information. | extrema | false | true / false | Display max/min information. | labels | hover | true / false / hover | Display Y-axis labels. | labels_secondary | hover | true / false / hover | Display secondary Y-axis labels. | nameadaptivecolor | false | true / false | Make the name color adapt with the primary entity color. | iconadaptivecolor | false | true / false | Make the icon color adapt with the primary entity color. | loading_indicator | true | true / false | Show loading indicator while attempting to retrieve a history.

Line color object

See dynamic line color for example usage.

| Name | Type | Default | Description | |------|:----:|:-------:|-------------| | value (required except in interpolation (see below)) | number | | The threshold for the color stop. | color (required) | string | | Color in 6 digit hex format (e.g. #008080).

Line color interpolation of stop values
As long as the first and last threshold stops have value properties, intermediate stops can exclude value; they will be interpolated linearly. For example, given stops like:
color_thresholds:
  - value: 0
    color: "#ff0000"
  - color: "#ffff00"
  - color: "#00ff00"
  - value: 4
    color: "#0000ff"

The values will be interpolated as:

color_thresholds:
  - value: 0
    color: "#ff0000"
  - value: 1.333333
    color: "#ffff00"
  - value: 2.666667
    color: "#00ff00"
  - value: 4
    color: "#0000ff"
The example above will result in the following colors of the graph: if value is
  • between 0 (including this value) and 1.33333, the color is #ff0000,
  • between 1.33333 (including this value) and 2.666667, the color is #ffff00,
  • between 2.666667 (including this value) and 4, the color is #00ff00,
  • equal to or more than 4, the color is #0000ff.
As a shorthand, you can just use a color string for the stops that you want interpolated:
- value: 0
    color: "#ff0000"
  - "#ffff00"
  - "#00ff00"
  - value: 4
    color: "#0000ff"

Action object options

| Name | Type | Default | Options | Description | |------|:----:|:-------:|:-----------:|-------------| | action | string | more-info | more-info / navigate / call-service / url / none | Action to perform. | entity | string | | Any entity id | Override default entity of more-info, when action is defined as more-info. | service | string | | Any service | Service to call (e.g. media_player.toggle) when action is defined as call-service. | servicedata | object | | Any service data | Service data to include with the service call (e.g. entityid: media_player.office). | navigation_path | string | | Any path | Path to navigate to (e.g. /lovelace/0/) when action is defined as navigate. | url | string | | Any URL | URL to open when action is defined as url.

State map object

| Name | Type | Default | Description | |------|:----:|:-------:|-------------| | value (required) | string | | Value to convert. | label | string | same as value | String to show as label (if the value is not precise).

Aggregate functions

Recorded values are grouped in time buckets which are determined by groupby, pointsper_hour configuration. These buckets are converted later to single point/bar on the graph. Aggregate function defines the methods of that conversion.

| Name | Since | Description | |------|:-------:|-------------| | avg | v0.8.0 | Average | median | v0.11.0 | Median | min | v0.8.0 | Minimum - lowest value | max | v0.8.0 | Maximum - largest value | first | v0.9.0 | | last | v0.9.0 | | sum | v0.9.2 | | delta | v0.9.4 | Calculates difference between max and min value | diff | v0.11.0 | Calculates difference between first and last value

Theme variables

The following theme variables can be set in your HA theme to customize the appearance of the card.

| Name | Default | Description | |------|:-------:|-------------| | mcg-title-letter-spacing | | Letter spacing of the card title (name option). | mcg-title-font-weight | 500 | Font weight of the card title.

type: custom:mini-graph-card
entities:
  - entity: sensor.energy_daily
name: Energy consumption
hourstoshow: 168
aggregate_func: max
group_by: date
show:
  graph: bar

Data aggregation functions

You can decide how values are aggregated for points on graph. Example how to display min, max, avg temperature per day from last week.

mini<em>temperature</em>aggregate_daily

type: custom:mini-graph-card
entities:
  - entity: sensor.outside_temp
    aggregate_func: max
    name: Max
    color: "#e74c3c"
  - entity: sensor.outside_temp
    aggregate_func: min
    name: Min
  - entity: sensor.outside_temp
    aggregate_func: avg
    name: Avg
    color: green
name: Temp outside daily (last week)
hourstoshow: 168
group_by: date

Non-numeric sensor states

mini<em>binary</em>sensor

You can render non-numeric states by providing state_map config. For example this way you can show data coming from binary sensors.

type: custom:mini-graph-card
entities:
  - entity: binarysensor.livingroom_motion
    name: Living room
  - entity: binarysensor.corridormotion
    name: Corridor
  - entity: binarysensor.masterbed_motion
    name: Master bed.
    color: green
  - entity: binarysensor.bedroommotion
    name: Bedroom
name: Motion last hour
hourstoshow: 1
pointsperhour: 60
update_interval: 30

state_map:
  - value: "off"
    label: Clear
  - value: "on"
    label: Detected

Showing additional info on the card

изображение

It is possible to show a state without displaying a graph for a sensor. Imagine there are two CO-2 sensors & one humidity sensor; graphs are displayed for the CO-2 only, and the humidity is shown as a state only.

type: custom:mini-graph-card entities:   - entity: sensor.xiaomicg1_humidity     show_state: true     show_graph: false   - entity: sensor.xiaomicg1_co2     color: green     show_state: false     name: CO2-1   - entity: sensor.xiaomicg2_co2     color: orange     show_state: false     name: CO2-2 name: Humidity hourstoshow: 4 pointsperhour: 60 show:   name: true   legend: true   icon: false   labels: true
This method may be also used to add a calculated value with it's own aggregate_func option.

Accessing attributes in complex structures

When using the attribute option in the entities object, you can access data in structured attributes, such as dictionaries and lists.

Accessing dictionary attributes
Suppose you have data stored inside a dictionary attribute named dict_attribute
dict_attribute:
  value_1: 53
  value_2: 64
  value_3: 72
Such data should be addressed as dictattribute.subattribute:
type: custom:mini-graph-card
entities:
  - entity: sensor.testingobjectdata
    attribute: dictattribute.value1
    name: value_1 from dictionary attribute
image
Accessing list attributes

Suppose you have data stored inside a list attribute named list_attribute:

list_attribute:   - value_1: 67     value_2: 65     value_3: 93   - value_1: 134     value_2: 130     value_3: 186   - value_1: 201     value_2: 195     value_3: 279
Such data should be addressed as listattribute.index.subattribute:
type: custom:mini-graph-card entities:   - entity: sensor.testingobjectdata_list     attribute: listattribute.0.value1     name: value_1 from first element of list attribute
image
