I can get the total daily production.
I can get the instantaneous production of individual panels.
But I haven’t been able to find a way to get the daily production of individual panels like on the SolarEdge website.
Does anyone know how to get the daily production of individual panels?
It appears to me as if you don’t understand the difference between energy and power.
On the original SolarEdge screen the values are in kWh or Wh, which is energy, and on your own screen most of the values are in W which is power.
You are only talking about production, like daily production and instantaneous production, but you probably mean to say daily energy and instantaneous power?
See Energy vs Power for an explanation of this.
If your power sensors are updating fast enough you can create energy sensors using the Integral integration.
OK, that’s much too slow to get a reliable energy value.
I saw there is an old SolarEdge Local integration that supports the local API, that probably is delivering the data much faster, so is your inverter still providing this local API?
If not, I suppose the only option to get fast updating energy sensors is to add your own local sensors to measure the values.
Another option might be to add the original SolarEdge web interface directly in Home Assistant with a Webpage card?
Or you might be able to get the data from the SolarEdge page using a RESTful Sensor?
If you want to display what the SE portal displays, you could probably just add an iFrame or some such frontend card to actually display your SE portal in the form of a widget
SolarEdge Local is a dead end option, unless your inverter has very old firmware that still allows the HTTP server over LAN. Since for at least the last 4-5 years all SolarEdge firmware blocks HTTP from LAN.
