Shelly EM & Energy dashboard : lot of data missing

Hello

I’m new to HA (since yesterday :slight_smile:). Running it in VM under MacOS - fresh new install, with added auto-detected Shelly EM

Channel 1 is consumption from grid.
Channel 2 is solar production.

I added to the Energy dashboard the Channel 1 Energy to start & check.

For an unknown reason, a lot of data are missing in the stat graph, while checking history of Channel 1 Energy show regular data collected. On Shelly app, everything is fine as well.

Any clue on the issue with the panel or my configuration ?

Thanks for your help.

I am auto-replying because I think I have found the solution to the problem.

The problem seems to come not from HA nor Shelly, but from a setting in Virtualbox. In the system acceleration settings of the VM, disabling the paravirtualization interface solves the problem. I now have regular and coherent data.

I found track of this solution on the internet where people have solved problems of late hourly triggers of their scenarios (test done, I had the problem too, solved with the deactivation of this parameter).
