Flex-table-card

odyskat · November 1, 2022, 5:05pm

Hi, noob here.

I’m trying to create a table with temperature readings at specific times throughout the day.
So for example:
---------------------------------- 7am----10am----1pm
----------------------Sensor 1----20------21-------18
----------------------Sensor 2----25------30-------27

I use multiple command line sensors to retrieve a value from the default SQLite database(utilizing SQL queries in python and transforming that data to floats).

Now every sensor gives me one reading for a specific time, so the first sensor gives the value at 7 am, the second gives the value at 10 am, etc…

How can I display different entities’ values in each column of the flex table card?

1 row = 1 entity.
Each column may contain:

a state (sensor.my_sensor.state);
an attribute’s value (sensor.my_sensor.my_attribute);
a processed state’s value (Foo(sensor.my_sensor.state));
a processed attribute’s value (Foo(sensor.my_sensor.my_attribute)),

but not these:

a combination of a state & attributes (sensor.my_sensor.state + sensor.my_sensor.my_attribute + sensor.my_sensor.my_attribute_2);
data from another sensors.

Means - you need to PREPARE data before displaying them in flex-table-card - probably define a template sensor with attributes storing all your data.

@Ildar_Gabdullin thanks for answering so quickly.
OK, the one-row=one-entity policy is what I feared.

So how do I define a template sensor with all the necessary attributes?
If I understood you correctly, I need a new entity in my database with one collum for each value at a specific time.
So how can I do that and how will I feed it values?
Will the same entity be usable with other dashboard cards?
Any links to guides I can follow?

You need to create a template sensor which is not to be discussed in this thread.

I am using the flex-card to show some stock data (yahoo finance integration).

Is there a way to make a column data (lets say the stock price) having the url, embedded (https://finance.yahoo.com/quote/AAPL), so when clicking on the cell value, you go to the web site?
If yes, how to I code this, https://finance.yahoo.com/quote/ and then adding the value to the url?

type: custom:auto-entities
filter:
  include:
    - entity_id: sensor.some_sensor
card:
  type: custom:flex-table-card
  columns:
    - name: object
      data: state
    - name: object
      data: some_attribute
      modify: '''<a href="'' + x + ''">Link</a>'''

Tomahawk · November 7, 2022, 11:27am

Thanks. The link works when

  - name: Link
    data: symbol
    modify: '''<a href=https://finance.yahoo.com/quote/'' + x + ''>Y</a>'''

Is it possible to use the url for the icon column, so the icon (arrows) becomes the url-link?
Somthing like, witch do not work:

type: custom:flex-table-card
entities:
  include: sensor.yahoofinance*
columns:
  - name: Trend
    data: icon
    modify: '''href=https://finance.yahoo.com/quote/'' + x.symbol + ' ' + ' target="_blank"''
  - name: Råvarer
    data: friendly_name
  - name: Pris $US
    data: state
  - name: ∆%
    data: regularMarketChangePercent
  - name: Link
    data: symbol
    modify: '''<a href=https://finance.yahoo.com/quote/'' + x + ''>Y</a>'''

Ildar_Gabdullin · November 7, 2022, 11:31am

May be, try to create it by using html, have not tried yet.

Tomahawk · November 7, 2022, 11:38am

My skills are limited, so trying with cut and paste… The code over does not work and cant find other examples.

Ildar_Gabdullin · November 7, 2022, 12:48pm

So are my skills)) never wrote HTML stuff before.
Will try to do it in a week when will be free a bit.

alexandrechoske · November 7, 2022, 1:04pm

hey, can you share more details how you did the table? I mean the Yahoo Finance infos in a table.
Thanks.

try this btw.

How to use an image as a link in HTML?.

Tomahawk · November 7, 2022, 4:13pm

The icon is one of the sensor attributes. Want this to be clickable to a chart.

type: custom:flex-table-card
entities:
  include: sensor.yahoofinance*
columns:
  - name: Trend
    data: icon
  - name: Stock
    data: friendly_name
  - name: Pris $US
    data: state
  - name: ∆%
    data: regularMarketChangePercent
  - name: Link
    data: symbol
    modify: '''<a href=https://finance.yahoo.com/quote/'' + x + '' target="_blank">Link</a>'''

Hi All,

I have a sensor with JSON attributes:

and want to export part into a table just showing the “valid_from” time and “value_inc_vat”. I have tried the following with no entries in the table:

type: custom:flex-table-card
title: Outgoing Rates
entities:
  include: sensor.octopus_outgoing.results
columns:
  - name: Start
    data: valid_from
  - name: Rate
    data: value_inc_vat

and then this:

type: custom:flex-table-card
title: Outgoing Rates
entities:
  include: sensor.octopus_outgoing
columns:
  - name: Start
    data: results.valid_from
  - name: Rate
    data: results.value_inc_vat

I get this:

When I do this:

type: custom:flex-table-card
title: Outgoing Rates
entities:
  include: sensor.octopus_outgoing.results
columns:
  - name: Start
    data: results

I get:

Any pointers gratefully received!

Ildar_Gabdullin · November 28, 2022, 7:09pm

Cannot reproduce your case, try this:

  - name: xxx
    data: results
    modify: x[0].value_exc_vat

comm · November 28, 2022, 7:34pm

Thanks for the pointer, although that still doesn’t seem to work:

Ildar_Gabdullin · November 28, 2022, 7:45pm

Well, cannot help then, have no similar sensors.

I spot an array of Octopus Agile Export!

Yup, the flex-table-card is a bit tricky to set up, particularly with sensor attributes. I have several tables and am finally getting the hang of this (rather nice) card. If anything is wrong, then all you get is a pink square with an error message…

I have manipulated my data into different sensor arrays, so my names will not match yours, however, the following works for me:
Sensor - octopus_agile_prices (which has an attribute)
Attribute - array (which is an array of objects)
Start time - from (which is the Octopus valid_from)
Export value - export (which is the Octopus export price - I have combined both import and export into one array using JSONata, but that is another story…)

The entities: include should be the sensor (at the top level only).
This makes the card look at the sensor. Then for each column we want, we set the data as the attribute name, which makes the column look at the attribute.
Then for the value, we need the ‘modify’ operator to pull out the field from the attribute, hence ‘x.field_name’ where x represents the entity attribute, and the field name is the bit we want.

The fact that the (final) data is an array causes the card to display rows based on each value in the array.

You probably need something like

entities:
  include: sensor.octopus_outgoing
columns:
  - name: Start
    data: results
    modify: x.valid_from
  - name: Rate
    data: results
    modify: x.value_inc_vat

(errors and omission excepted)
EDITED extra ‘columns’ was an error!

WARNING - the ‘modify’ function calls JavaScript eval() as part of what it does, and this can be a security issue, hence the use of this feature is avoided by many.

Ildar_Gabdullin · November 28, 2022, 9:59pm

Now I am curious…
Since you specified only one “sensor.octopus_outgoing” sensor, then only one row is expected to present in the table - how do you get many rows?
~~Also, a person above provided a screenshot from “Dev tools → state” where there is one “results” attribute which is an array. And in your example you specified an “array” attribute. -~~ I see that you edited the code, it differs from a screenshot.
Since your code is a GUESS not a really working code - I also doubt that it will work.

Can anyone propose me a sensor with a similar structure?
I need it for testing…

OMG, you are right - the code works.
I used an OpenWeatherMap sensor:

type: custom:flex-table-card
entities:
  include:
    - weather.home_openweathermap
columns:
  - name: date
    data: forecast
    modify: x.datetime
  - name: condition
    data: forecast
    modify: x.condition
  - name: temperature
    data: forecast
    modify: x.temperature
  - name: templow
    data: forecast
    modify: x.templow
  - name: pressure
    data: forecast
    modify: x.pressure
  - name: wind_bearing
    data: forecast
    modify: x.wind_bearing
  - name: wind_speed
    data: forecast
    modify: x.wind_speed
  - name: precipitation
    data: forecast
    modify: x.precipitation
  - name: precipitation_probability
    data: forecast
    modify: x.precipitation_probability

The strangest thing for me is that:
– there is only ONE sensor is specified - so only ONE row is expected;
– the attribute “forecast” is an array - so a “forecast[2].condition” syntax is supposed to be used:

Probably the author is expanding one “array attribute” to several rows - as it mentioned in the docs:

Then I do admire this card even much more!

More explanations are here.

Biscuit · November 28, 2022, 10:50pm

My code certainly works for me, and yes I have spent a lot of time experimenting with this card to try and figure out how it all works.
My sensor attribute is an array, and rather obviously I called it ‘array’ because it is…

The tricky part about this card is the way it works out the 1 entity = 1 row OR multiple values = multiple rows (same entity - one value per row).

If you have a sensor with one value, then that ends up in 1 row. The columns then become holders for different sensor values.
If you have a sensor.attribute with one value, then that ends up in 1 row. The columns are again for different sensor or sensor.attribute values.
If you have a sensor.attribute that is an array, then that ends up with each row=1 item from the array, but the card cannot get at the data directly, hence the use of the modify function.

The code behind the card seems to cast the card into one-row / multiple-rows per entity based on the first item it sees, and then you have to work with the card based on that. Takes a little bit of thought and a lot of experimentation to get the best from this.

comm · November 29, 2022, 10:46am

Hoorah! Yes that works! Although I had to remove the second columns: in your suggested code. And your explanation is really helpful in aiding my understanding, thank you.

And yes, it’s Octopus Agile Export

Thank you so much!
