Insights Graphs for Homey

This app allows you to export any Homey Insights data into beautiful graphs.

Currently has support for:

  • :green_circle: Color picker for graphs in trigger card
  • :heavy_plus_sign: Select a time window (day, week, month, etc…)
  • :rice_scene: Graphs image tag
  • :black_circle: Light, dark or transparante for auto light/dark mode graphs
  • :chart_with_upwards_trend: Graphs types: Line and bar

Exports can be easily scheduled by using a trigger card and Insights Graphs action card in a flow. You can schedule by day or week or with time window you need.

Download in the Homey App Store!

:gear: Install this app on your Homey and create a flow with the Insights Graphs action card

Cool app!
I just have a question: How did you handle the forced interpolation done by Homey?
The images you have posted shows temperature with 1 value pr hour. Homey is automatically interpolating values for every 5 minutes when selecting “24 hours”, even if my temperature sensor is only posting a value every 20 minute :thinking:


Looks nice, out of curiosity what generates the graph and converts it to an image?


I have written a data normaliser class that takes care of this :innocent:


Chart.js is used and then the end result is converted to an image


Do you have the source code public somewhere I can have a look?

As Homey already screws the original data by interpolating to 1m/5m/1h/6h intervals, its interesting to see what you do on top of this to try to correct the data :sweat_smile:
Are you stripping all the similar values to remove the stair-case graph?

My day-job is timeseries data, that’s why this is interesting :wink:


We do not have the source code public. Should we want to do this, the app must first be published.

What I do is not too cool haha.

I use a timestamp convert all Homeys data to that timestamp and make a new collection with the choosen timestamp. Them all data gets combined and I calculate the highest values. And return my own new smaller list.

The app is out now! Graphs all your Home Insights data right now and send it out with your favorite messenger app!

Try the live version here:

Isn’t it more simple to just use all the available data points and let Chart.js do the “hard” work of converting them into a nice graph? Then you can leave out the step of creating your own smaller list. That way the chart should be a bit more accurate, right?

You can configure Chart.js to show you a max amount of ticks on the xAxes using maxTicksLimit .

I did the same for the charts in my own dashboard:

It would be even cooler to be able to do all of this locally, without the need of image-chart.com. Have you thought about using something like this?


Thanks for the feedback bas I’ll take a look!
I decided for chartjs with a site to make the app more lightweight but I’ll run some tests. It would be better to run 100% locally.

I will also work in making a device for homey so you can see your graphs within the homey app.


I did some testing myself, and chartjs-to-image works pretty great.


I’m making an update for implementation thanks for the feedback.

Awesome! I’m curious how it will turn out.

This is what I came up with so far:

I am plating around Sith the app but i zee you use aan app to send the image over Whatsapp, what app is that? I am using Callmebot but it doesn’t have the option to send aan image.

Hi, that is a app in development in collaboration with @martijnpoppen :wink:

Good to hear/read. Any idea when it wil be released?

P.s. As I am Looking for it I am willing to help with testing

How do you import it to image-charts?
Not sure how to connect from flow to image charts :smiley:

What exactly do you mean? You choose any trigger card. Then the insights graphs advanced action card. Then a message action card and choose the graphs tag as image there.

Gotcha thanks :wink:
Very nice app :slight_smile:
