@parkghost: I know this is offtopic here, but can you please help with chuangmi.plug.212a01? The issue is very similar, values are not calculated at all (daily) or in a wrong way:

I have four chuangmi.plug.212a01, all of them are China version and connected to China server, and there is no problem you mentioned.

Regarding the source of power_cost_daily is from the server, not the device, you can enable miot's debug log and check the following information.

Thank you for your guidance, I will have a look at it. I think the issue comes from the fact, that my plug is connected to the EU server with the modded Mi Home app, and most probably the values are not calculated properly, as the plug is China only. I will try to move it to the Chinese server and check if the sensors in HA turn ok. Thanks again.
