Total Power Usage reading on Dasboard is wrong

[Sparky]

I have the following setup.

Domoticz on Raspberry Pi4, 3-phase smart meter Enexis Sagemcom directly connected through P1
Solar panels connected on single phase (L3) with Goodwe converter (data is read using goodwe plugin).

Power readings from Smart meter all look OK. Usage from all three phases, and delivery (when there is enough sun) on L3 all report correct values
I have also created a virtual meter that calculates total power used in my home

However one exception.
I've taken a screenshot earlier today where I use 2W on L1, 192W on L2 and 354W on L3, and my solar panels are generating 583W, so I'm using 194 W via L1 and L2, and returning 229 W via L3. The power meter tile in others tab correctly shows 195W, -229W and when checking the meter itself it does show -34W. The virtual meter shows 549, which is the correct total power consumption in the house. So far so good, this is all correct.

However on the dashboard the power meter only shows the return power on L3 (so -229W), and not both used and delivered, or preferably a single reading on the dashboard the combined value for both (in this case -34W).

I know that worst case I have to create a second virtual meter that calculates true power taken from or returned to grid and show that on the dashboard.

However best would be if the power tile for the dashboard can be corrected to show true power usage/return from/to the grid, of if there is a way to re- configure the readout of the power meter on the dashboard so it shows the correct info?

Hi,
did you tried the last beta version?
10 days ago it was fixed a problem measuring energy when power goes negative, but that bug seems not to be related to your problem, anyway I recommend you to try the to upgrade to last beta version.

A question: how is configured the L3 device?

Will try beta this weekend.
And this is not so much a bug in the calculation, but more on the difference between what is displayed in the others tab vs the dasboard.
On the dash what I want to see is true (combined) power from/to grid, so in the below case -34 W

The devices (verbruik L1, L2 and L3) are part of the 3-phase smart meter readout. The smart meter also returns values for delivery on L1, L2 and L3, but as my PV system is connected to L3 that's the only one relevant for showing
