Automatic refresh of dashboard charts

[kvolleberg]

Hi Dennis,
First off: happy new year!

I have upgraded dsmr to the 1.5 version. You've made some nice enhancements.
I noticed you updated the dashboard page. In my 1.4 version, I included some code to automatically update my electricity charts with the latest reading. I thought this was useful for realtime monitoring; this saved me some unneccessary F5'ing.

Now, with the 1.5 version, my local mods have been removed and, as things have been changed quite a bit, it's not a matter of copy-paste anymore. Plus: it's not that robust to do this locally.

Therefore: I would like to suggest an auto-update method in a next version. What are your thoughts on this?

Happy new year to you as well!

I think it's a good improvement, so I'll surely add this later.

Regarding your local modifications, it's actually very easy to patch this feature in this version. This should do it already:

diff --git a/dsmr_frontend/templates/dsmr_frontend/dashboard.html b/dsmr_frontend/templates/dsmr_frontend/dashboard.html
index 8058e14..5ce2b45 100644

                 /* Auto refresh. */
                 update_header();
                 setInterval(function(){ update_header(); }, 2500);
+                setInterval(function(){ update_graphs(); }, 5000);
                 
                 initialize_graphs();
             });

So juste add setInterval(function(){ update_graphs(); }, 5000); in dsmr_frontend/templates/dsmr_frontend/dashboard.html around line 368 and save it. (5000 = milliseconds refresh rate)

A browser page refresh should suffice to apply the changes.

Merged to development branch.

This ticket has been part of the new patch that was just released. It should update your dashboard graphs every few seconds.

Please note that it may take a minute when you have enabled the 'group readings by minute' setting in the configuration.
