Dynamic ESS1

Hi has any one tried to use Dynamic ESS
I have had set up with my Octapus account but it does seem to work
I.E when the tariff is low ( 2am to 5 am ) it won’t charge the batteries but starts to charge from the grid when tariff is high ( 4pm to 7pm)

Even if I set the discharge level on VRM to 50% 25% even 90% seems to make no difference
I have had to turn it of and use my own node red algorithm for charge cycles from the grid to work correctly but it is winter and solar not very good
Also tried with fully charged battery and expect to export to grid on peak rate not a low rate as I have seen it do
