Low-carbon energy consumed shows negative value in energy dashboard

[proffa84]

The problem

Energy dashboard's low-carbon energy consumed start to show negative values. Also Low-carbon energy is totaly different than used grid energy("out of scale")

I think that used energy in home(from grid) have some issue because normaly daily energy usage is 8-9kWh, at this time of day(19:00) about 6-7kWh and now I have only 3,9kWh. Is it possible that "some data is missing" and thats why I have that problem?

I update core-2023.5.0b0 -> core-2023.5.0b1 17:35 (about 2 hours ago). I did'n check the values before update so I can't say that did I have same problem with core-2023.5.0b0.

core-2023.5.0b1

After I updated Core-2023.5.0b4 and waited until the next day(full, "clear day"), HA started showing correct value.

i and i think lots others have been having this issue. at first i thought it was related to some misreported energy usage values but it persists today, and all my energy usage is as expected. one thing to note is that sensor.co2_signal_grid_fossil_fuel_percentage is showing an expected value at all times

This looks to be a same or related issue to #79774 which predates 2023.5 -- the fossil energy consumption websocket endpoint appears to do very weird things with missing data, and unrelatedly the midnight-1am period seems to (in some cases?) be assumed as 100% low-carbon. More of my investigation is in comments on that issue.
