I have heard if I say IoTaWatt some of you will stop listening. I really hope that isn’t true. I bought my first IoTaWatt from your store and still use the emoncms service and generally find it useful.
One thing that really bugged me when I first started using emoncms, which was years ago, was that following the example of creating a feed I was unable to see my data and it looked like it wasn’t working. Now I figured it out pretty quickly, but the graph defaults to showing 7 day’s worth of data. So there is no way the typically small amount of data will show up. Over the years I figured out how to zoom, but never liked the experience.
In the last year I have been using Grafana and really like its experience for selecting time periods. There was some discussion in the IoTaWatt forum about allowing more time selections. This was something I had always wanted. So, I said how hard could it be ?
I first added more buttons, which was pretty easy. But got feedback that a drop-down might be better. So I researched that and sure enough it does look better.
I just took a look at the code for emoncms and while it has moved on, it looks like the basic technique will work with the current code. Is this something you would be interested in?
If so, I can create a PR for it.
