Agile yes, i believe; Intelligent, no (neither car nor HV are 'compatible', i.e. the Octopus software cannot interface with either the SAIC API or the HV API). If you've been following the FBook threads related to this, you'll have seen that HV are hoping to fettle their software to be able to interface to OVO's around now-ish; when any possible interface to Octopus Intelligent might happen is, it seems, either not known or not on the current (sorry) HV task list. Have you considered E.On Next 'Drive'? - it is more expensive than OI at 9.5 p/kWh overnight, but that overnight rate is for 7 hours from midnight to 07:00 - and doesn't need any interfacing software. Might it be worth doing the sums on that?
