if you want to plot e.g. the consumed power[watt hour] (= consumed energy in indigo terms ) over time and start at 0 every day / week/month/ year this is how you do it:
1. define your source:
in
you select the device and set: to e.g. reset every day (options are day, week, months, year and "period"; you can define any time period (e.g. 5/5/2017 - 10/9/2018 which does not make sense .. but you can set 10+ + periods )m In addition to just adding this up you can also define cost per hour on a day / week / period. in the section at the end . Then you could show cost in $.
2. create a plot device, e.g. consumed power daily
- in the top section
=reset the x,y limits and set the descriptions as you like
=click confirm
- in the bottom section
= add new line
= select the data source you just created
= select line type eg solid line or histogram
= click confirm
= if you can see the indigo server screen you can enable experts tools and click on update and after 5 secs click on show.
Will add some more screen shots. unfortunately my energy meter is not working well. It has a bad z-wave connection and only updates when I push it . So i don't have nice data to show. .. one of the many things left to d.
