Hi
I installed HA and setup the sigenergy modbus integration. The dashboard however shows the wrong daily solar generation. Looks like it is showing double the amount? Has anyone come across this?
Which dashboard? The energy dashboard?
Every day or two 100 posts are new on this forum. When you want help from the ones that are using the same integration you use, then this is not the best way as you need to be lucky to have the right person looking in here. You can search for the integration and post under a topic, you can create an issue on the github page of the integration or you try a more general approach, so the share of people that can help you is much bigger.
When you do the last part then please share more info like screenshots, where the integration is coming from, custom code or settings
Not using Sigenergy but …
I have seen that my Tesla Solar Production Meter (I use a Tesla Powerwall Battery, but my microinverters are Enphase) seems to be about 7.5% off (on a good day, and anywhere between 5.5% and 8% on a bad one) compared to the Enphase production numbers (which seem to be spot on compared to the power company’s power meter).
The Enphase consumption numbers are all over the place, though, because the CTs don’t properly consider the split between feeding power to the house, the battery, and the grid.
And the only way to measure power going to the battery is the Tesla CT.
I’ve figured it out with some template sensors & math, but it was a pain to get the numbers to fully align with the power meters - which is what counts from my perspective.
Had I not been able to do that, I guess I would have deployed my own set of CTs in the various boxes
