Bug: Energy tab switches to the following day too soon

I dont know what time exactly this happens, but I’ve noticed that at some point in my afternoon, the Energy tab switches to tomorrow. I assume there’s some timezone error here; I’m in San Francisco. Most other things look correct, so the timezone on my devices appears correct.
It’s still Tuesday here despite what this claims.

I have a similar issue with it switching too late. Refer issue #2 Fronius & Tesla Issues with Homey Energy. Notice in video when I click on today (local time is 06:47) it goes N-1, and yesterday is N-2. Looking at it now at 13:00 local, Today & Yesterday buttons work fine. Feels like European time?

Confirmed today it appears to be set to GMT. At 10:00 local time Homey Energy switches from yesterday to today.

Raised support ticket for this as it looks like a bug with non GMT timezones.
