Was on my travels around the www earlier and found this linked to from the victron community forum, thought some here may be interested.

I've not read this in any detail, this is just what popped up of interest...
Dynamic ESS is an algorithm that aims to minimise the costs made on the grid and battery:
By scheduling charge/discharge cycles of the battery,
While taking grid limitations, battery specifications and day ahead energy prices into account,
When it can, it also considers the consumption and solar yield forecasts when scheduling.
NOTE: Right now Dynamic ESS is still in beta and only available via the beta VRM.
There's a subsection 'uk' where it says
"We are aware that the provider Octopus offers day ahead pricing, but as these are not offered via the ENTSO-E API, we are unable to process those. Eventually we will probably support these prices, but will take some time.
Also in the UK, (fixed) prices are known to change at the half hour instead of the whole hour (where our system works with). The work-a-round is to add the average price of in the overlapping hour. So if the price changes from 40 cents to 20 cents at 16.30, fill out a price of 30 cents from 16.00 - 17.00.
Adding better support for this will eventually be done, but as this also affects graphs and the scheduling, it might take a while."
Also
Q: Does the system work in the UK (or any other non-EU country)?
If your provider has “fixed” tariffs which are steady, but differ on hourly intervals, then yes. You can set the system to use a fixed contract. If your provider has hourly changing tariffs that are not covered by the ENTSO-E API, then you are out of luck for now. But if there is a public API and you let us know where we can fetch the information, we will gladly add it.
So you may be able to do hourly updates, but not 1/2 hourly (yet)
Looks like there is some option for user developed mods via something called "Node Red"
If you want to read more, the main thread title on the Victron community site is "Dynamic ESS on Beta VRM"
enjoy!
[EDIT. This is a 'beta' development item and not part of main victrons system yet. Please see top of https://community.victronenergy.com/articles/256073/dynamic-ess-on-beta-vrm-part-4.html ]
