Battery power behavior with Deye inverter

[sofkaski]

Has anybody had a similar observation:

I have had recently my battery disconnected for maintenance. The sensor sensor.inverter_battery_power shows still some varying positive power below 10 W. This must be some phantom since the battery circuit is physically open. (My setup is using Deye LV 3-Phase Hybrid Inverter. Inverter definition file is deye_sg04lp3.yaml.).

There is nothing wrong in the integration since the value comes from the inverter. I was just wondering if anybody has some idea why that happens?

And did that value change during that disconnected period or stayed frozen?

[sofkaski]

It is varying. It seems that the variance correlates to overall power consumption or production, or both. Example:

That's weird but my guess is that has something to do with the precision again. You are gonna have to ask Deye about that. 🤔
