Smart tariffs such as Octopus intelligent do not recognise Hyundai API, so for Hyundai to be compatible with the said tariff, you need a charger which is compatible, which Ohme is! As a smart charger it will be compatible with any smart tariff and also act, as a dumb charger in the same way your BP Pulse will, if you wish it to.
Its a no brainer to swop 🙂
