I am experiencing similar, but not quite the same as I am using cumulative energy for v3.

For me, today’s (2021/06/30) energy used column is shown all zeros despite my logs show OK 200: Added Status and scripts are unchanged compared to yesterday (and the past year). @bankstownbloke, can you please check?

v1 is handled properly, v3 seem logged but shown 0, it is monotonic, so there is no large value at midnight that would mask later energy values:

UPDATE: now I tried deleting live data for 2021/06/30 and re-uploaded based on local logs, no change to above behavior
