Generation total reads 0 every morning at start

[bytesinmotion]

I have a "winter problem" at the moment. Every morning when the NOAH starts (both I have) I get 0 value for total generation. Like 2-3 readings and then after 15 minutes it returns to the real value of over 1000. Now every day I have a jump in generation_total in Home assistant. Any idea why this is happening?

Same problem here. Every morning when connected, it shows 0 kWh total generation, then after some time the correct total appears. This messes up my Home Assistant energy statistics. It first happened to me on November 27, 2025, and every day since.
Is it a bug? Do you have any ideas?

I get the value once. Today for example at 08.05 - the next reading at 08.33 gave the correct total from yesterday night again with 0 gain. Connectivity was posted at 07.59

Same issue here since a few weeks. I think it's not an issue of the integration but of the Noah actually reporting zeroes. In my case, also SoC is reported as zero during the 'morning wakeup'. It then sometimes also resets my SoC limits from 20/90% to 10/100%.

Started using my own HA integral of Solar Power, that has a finer resolution than the 100 Wh increments of Noah anyway.

Having the same issue STILL. Any fix on this?

Yeah, I created a template that checks for values before setting the state. So a copy of the sensor that unfortunately makes comparing historical values not possible ...
