Getting spikes using SunGather feeding into Home Assistant Energy dashboard

[insertactivate]

Getting spikes using SunGather feeding into Home Assistant Energy dashboard when the values suddenly drop to 0 and then up again (see e.g. 2:27 in attached snapshot) to previous value that then adds to the accumulated energy for a day which often doubles the total solar energy for a day.

Adding one more screenshot which covers 3 days (starting a bit late the first day). Events when data goes to 0 and then back again to previous value which then adds to the total energy sum and makes it incorrect (doubles it): day 1 at 6:24 PM, day 2 at 2:27 PM and 6:00 PM, day 3 at 10:45 AM and 3:35 PM.

I have exactly the same problem. Event tried to create a secondary "utility meter" sensor from the Sungater's daily generation sensor with a "Periodically resetting" setting on, but that didn't help.

So far I have "solved" it with a filter in Home Assistant; https://community.home-assistant.io/t/issues-in-energy-dashboard-with-accumulated-solar-production-values/652460/9

Same issue here. Thanks for the workaround tip @insertactivate!
