Solar power not showing on chart

[Emmoore103]

Describe the bug I have added the new pv daily prediction chart and it works except for the PV output line (orange) that is just a flat line.

I made sure the sensor was correct (format - sensor.givtcp_xxxxxxxxxx_pv_power). This I copied from Entities in GivTCP. I checked there was an output to the entity which there is.

Expected behavior I expect the graph to show actual PV input.

Predbat version

7.22.2

Environment details

• Givenergy
• Standard HAOS installer
• GivTCP is in MQTT - not sure if that is relevent.

Screenshots

Log file Can you capture a log file from the time of the issue, debug mode is not normally required. If you are not keeping the full logs then please enable this in appdaemon.yaml (see the installation instruction in the Predbat docs area for details on how to do this)

I set this chart up myself yesterday and had the same problem.

Tracked it down to I have my PV power entity set to kWh not Wh so the line was appearing as zero.

If this is the same for you, the fix is to change the line:

transform: return x/1000;

to:

transform: return x;

I spent the rest of the evening trying to enhance the chart to show multiple stacked PV power's from my three arrays, but couldn't get it to do this as well as display the PV forecast and PV10% forecast as well. I could get one bit to work but not everything together on a single chart.

Thank you. That has done the job. Interesting that it is understandably jagged due to the passing cloud etc. I wonder if it would be possible to make an entity that smooths out the graph by some sort of averaging. Probably difficult and not that important. I can at least see generally what is happening.

[Emmoore103]

Just to show what I am now getting.

I think this is now correct, but any comments greatly appreciated.

Looks right, you can try a longer average period e.g

group_by:
  func: avg
  duration: 30m

Hi Trefor.

Thank you for confirming and for the code to try.

Brilliant work as always.

Kind regards Eric

Here's my attempt to get this chart working.

The bottom is the 'out of the box' chart showing one PV array which works fine.

But I have 3 arrays so really would like to see all 3 of them on the same chart, the top is the adapted chart showing 2 of my arrays. Once I get this working I can then add the 3rd. I can include 3 arrays as lines by just duplicating the entity definition in the chart but I really want the array solar generations to be stacked one above each other, but when I do this I end up with the 2 solar, the PV and PV10% values all being stacked which is clearly not right!

The best I have got to is to change the group_by for the predbat_pvtoday to 'diff', but this only works for one or other of the predbat areas, can't get both to work.

Any ideas @springfall2008 ?

There is a stacked option but I think its global (the entire chart).

Maybe create chart string 1 and then the total as that's the same thing?
