Request: Trending / Graphing / Analytics

I have been looking for a way to do some basic analytics on my hubitat data, mainly temperature etc. I wonder if Sharptools.io could do this? Not sure how things work in the background. Is Information requested from my Hubitat when I load my dashboard or is it on an interval?

What kind of temperature analytics were you hoping to do?

Behind the scenes, SharpTools sets up event subscriptions in Hubitat. So whenever events happen they are pushed to SharpTools and down to your browser (no polling involved).

Maybe Analytics is too strong a word. I was looking more towards graphing of data.

My HA is in my summerhouse. I have temp probes in all rooms and my additional shed etc. I would like to record these values in some kind of historical database and do correlation between outside temp and inside. Going a bit further than this it would be good to be able to graph on/off events of my heaters as well. Perhaps even on/off of events of other devices and deliver total on time etc.

I come from Vera and there I had a local service called DataMine which easily fulfilled my needs. I had also previously used Thingspeak in the cloud, but there are nicer looking services than that.

I know that some have set up Grafana on Hubitat, but it seems to possibly make the system unstable, so therefore I am looking at alternative options and I started thinking that perhaps Sharptools may be able to do this as it is connected anyway, and since states seem to be pushed to you, then I assume you already have the ability to graph it or forward to a solution like Thingspeak or better?

Ah, thanks for the clarification!

We aren’t tracking historical data at this point, but I have been thinking about what it would take to achieve some sort of historical trending of data.

There’s some short-term things we could do where we could ‘start’ a trend as soon as you open the page and each event that comes through would add a new plot on a trend (basically just recorded in your browser, but not stored), but I felt like that’s really just not good enough even as an initial release.

How far into history are you looking to go?

Anything really is better than nothing, but as soon as I have something I assume I will want more… so let’s say that full storage of all data would be required…this way one could run yearly analysis on the data. :slight_smile:

I would love to see a trending feature.
Even if it’s like:
X Amount of days == free
Any more requires premium.
Or the entire feature requires premium.

As long as all of the awesome features are lumped into one low monthly fee I’ll pay.

So, here I am again. Since I started this topic a lot has happened in camp Hubitat and there is now a good looking graphing application available calledHubigraph.

It only graphs data in the logs on Hubitat, but it is a start. However, I am not aware of any way to get this over to Sharptools for display.

Due to this I have been toying with moving my dashboard over to Hubitat (which would mean away from Sharptools), but the darn interface is so rigid that I just don´t have the energy to do that and I still like the simplicity and power of Sharptools.

Is there any way to display Hubigraphs on the Sharptools dashboards, or are you working away on a similar logging solution internally that I could use instead ?

Thanks for sharing! From a quick glance, it looks like they’re using Google Charts (cloud charting library) to chart the history data from Hubitat and then embedding that in an iframe to display in the Hubitat dashboard.

We don’t currently support arbitrary HTML / JavaScript for security reasons, so this won’t work today. That being said, we do have it on our hit list to enable the ability to build and use custom components and I think something like this would fit into that quite well.

In the meantime, I’ve seen other people take a similar approach by logging the data to Google Sheets and generating charts can be displayed in the SharpTools Media Tile. (This approach works in both Hubitat and SmartThings)

If you’d like more details on the Google Sheets approach, I’d be happy to write something up. The overall concept is:

  1. Install the Google Sheets Logging app in Hubitat and setup logging to a Google Sheet.
  2. In Google Sheets, create a Chart from the logged data
  3. Publish the Chart as an Image
  4. Copy the Link (to the published Image) and use the URL in a Media Tile with an appropriate refresh rate

That is interesting. I might take a look into that. I do wonder what will happen once you have amassed a lot of data ? On the other hand I guess you can do pivot tables and the like on the data.

Hubigraph has grown quite a lot over a very short period and it is nearly perfect, with the exception of not storing the data separately, so you are stuck with what is available in the logs at any given time. I know that it might be possible to go with Grafana or similar but I just want to keep things “simple” :slight_smile:

I went the google charts route as suggested, and in theory it works, but the problem is that sometimes there is no change of temperature and then the line in the sheet is filled with empties so that ruins the graph. In addition the image is of course static so no nice hovering over anything etc.

For other graphing this might work well though

Perhaps you could use a formula to standardize the values across a time interval. Maybe some form of time series interpolation.

Yes, I am sure that would be possible, but still I am left with “only” an image, and I wouldn´t even know where to begin with formula’s and such and that is the beauty of Hubigraph or cloud IoT platforms where this is all taken care of already. I am not a fan of re-inventing the wheel.

I think I will just start down the path of using the Hubitat dashboards for graphing with Hubigraph and continue with Sharptools for other dashboarding, even though ideally I would like one tool that does all and is available without VPN, but I guess I can´t have it all…

You know; you could just ask the HubiGraph creator to add long-term logging, I know the creator and he is always looking for ideas…
