[Feature]: Rolling graphs rather than fixed for a single day until 00:00 #49

Description

Currently the graphs are day bound meaning the end at midnight and show progress during the days as grey areas. Unfortunately these graps are always day based, so looking at it around 23:00 does not show any plans for after midnight.

Suggested Solution

Rolling graphs with 24 forecast rather than fixed for a single day until 00:00.

A better understanding of the generated plan would be a view roll in the hours of the next day including plan for usage and battery soc. This would give much more confidence that battery SOC over the night is sufficient the cover the expected load until the sun rises.

The way I envision something like this is to have the graps having a slightly larger view with some hours visible in the past and always have the next 24 hours as 'planned'. With each passing hour one hour from the past drops off from the left and one hour in the future is added on the right.

Expected usage, battery soc, PV forecast, loading schedules based on hourly prices etc.... can be rolled in as they become available.

With this when ever you look will have a 24 hour plans, even at 23:00 at night...

Thanks for the suggestion and agreed that it would be really nice. Looking always 24 hours ahead is unfortunately not possible (new energy prices only get published around 15.00). Which makes it hard to capture in an always functional graph. So for the Node-RED implementation adding this probably won't happen. That being said, the implementation in VRM is a lot more likely to get that. Though i cannot guarantee that will be already in the first release either.

Hi Dirkjan,

Thanks for the reply. I understand the node red version may not get this.

As for this:

new energy prices only get published around 15.00

The plan for after midnight (which is about 9 hours away anyway) can be adapted the moment prices become available. However, expected usage and thus battery soc could still estimated for the hours after midnight.

Admitted, having the information rolling when they become available will change the forecast dramatically. But as user of the schedule I rather have a changing forecast than no forecast after midnight as it is now, eventhough prices are available by that time.

However, looking forward to the VRM implementation of this.

To add to this, the new version has 48 hour graphs in (as soon as the new prices get in).
