I keep having very large energy spikes with the energy dashboard that are false positives. From what I can see others on Redditt and within the forum have seen the same issue.
When I go look at the device it reports the kWh at the low rate it should so it does not look to be the device as far as I can tell.
I can try but others have ran into the same issue and does not seem to be the sensors as the sensor data does not show the spike, it only shows 3.55 kWh.
This happens with me when I restart an energy/power measuring device (shelly) twice within an hour. HA apparently resets the increase-only measurement, after which it gets the old (huge) amount again from the device.
