Mathematical pseudo entity to sum up sensors?

Configuration
1

I’m not very deep into HA, yet, just dabbling with what the sensors deliver already and showing them in graphics etc. And I saw the energy tab present after installation.

Now with the solar inverter, I have the issues, that the inverter (or rather, the attached Solarman LSE-3 WLAN Stick logger, using the HACS Solarman integration) shows the real time power delivery by the PV on the roof per MPPT … but to use it in HA’s “Energy” tab, it seems I need to have the sum of it (similar issues for grid etc). Can I somehow simply create a pseudo device, that just mathematically sums up the three already present sensors and then provide that to the Energy tab?

Hello,

Did not really understand what you need but I suggest you to look for Riemann sum integral helpers and template sensor:

So you can add the power of each panel to a single sensor with a template and then calculate the power per time unit (eg kWh) to use it in the energy dashboard.

Hope it helps
