Hello,
thank you very much everyone for sharing your configuration.
I am having some troubles with the modbus connection to home assistant.
The first couple of days everything was working perfectly. However, then i started to notice some weird spikes in the dashboard:
This spike occurs every day for the last week or so. At some days it even reaches about 20kwh grid export at one hour in the morning, which does not make any sense. It also does not make sense, that the battery is charged at this time.
I looked into the home-assistant database values for further investigation. These is a cutout of the values i got for the e3dc_grid_export_power sensor this morning:

As you can see, there are no values for about 2 hours, and then an extreme spike.
However, i could not figure out, where this is coming from and how to solve this problem.
Is anyone else having this problem or knows a fix for this problem?
Thank you very much!
