I have two different solar arrays connected to one hybrid inverter. They have different capacities and point in different directions.
Consequently, I have two instances of the Forecast.Solar integration to predict what each array is capable of.
In the Energy Dashboard I can find no way to tell the system to use the sum of both of these forecast.solar instances, and so the predictive graph is wildly inaccurate, and is even out of phase with the actual solar generation - as I believe it is only tracking one of my two arrays.
I have two solar planes (arrays) connected to one hybrid inverter. One plane faces east, the other west. Consequently I have added the Forecast.Solar integration twice.
The Energy Dashboard automatically summates both, so the predictive graph is what I would expect, and I believe it is tracking both planes as required.
If you look at each integration, they provide several entities, one of which is sensor.energy_current_hour. It is easy to look at each for both integration and add them to check against the energy dashboard. In my case, one is 0.17 kWh, the other 0.14 kWh (cloudy day today). The energy dashboard graph is showing 0.31 kWh on the dotted line for ‘this hour’, ergo it works.
Perhaps one of your integration settings are not correct?
Both forecast.solar integrations were working correctly - as you say it is easy to read the values from each.
I did however find that only one of the arrays was selected in the Energy Dashboard settings - I just failed to click down the additional layer of hyperlinks to see the selection. Fixed now - and I trust will give better results tomorrow.
So it didn’t automatically select both. Possibly because when I set it up originally I didn’t think to set two instances of forecast.solar, but rather originally calculated the average direction of the two arrays (mine are nominally north and west) and had only one instance. So the system was working with an approximation of both arrays. When I later got smart, and created the second forecast.solar instance the dashboard didn’t automatically pick up the new one, but just continued working with the first one which was now accurate for only half my capacity.
