I have two RVs, a Nissan Leaf and a Kia EV6 and a Hypervolt Home 3 Pro charger. Intelligent Octopus Go is compatible, or so it says on their website, with both combinations of car and charger (ie Hypervolt & EV6 and Hypervolt & Leaf). The Octopus App is different and lists only the Nissan Ariya as compatible Nissan cars, therefore despite the website "Will it work for me?" page saying a Leaf is compatible, it is not according to their App. That strikes me as false advertising and shouldnt be allowed! OK, so now I'm on the Intelligent Go tariff (as the Hypervolt/EV6 combo works fine). Octopus tell me, eventually after much conversation with so called Help agents who know about as much about EV systems as I do, that I can only have one car/charger combo working. Thats not at a time, but ONLY one combo. They wont let me have two EVs registered! What? that sounds really daft. Trying to charge the Leaf is somewhat more difficult. Switch off Smart charging and charge the Leaf through the Hypervolt as a standalone set up should work. Well no, actually, it doesnt. Octopus takes over the charger and is very reluctant to release it to allow me to charge the Leaf. It takes a lot of effort to switch off the "smart charging" but it can be done if you persevere. Octopus might have some decent EV tariffs, but their help system on the telephone is hamstrung by the inability to speak directly to the so called "smart team" who look after the EV side. The people who answer the phone are next to useless and do not know how the EV side of the business works. As a consequence they cannot "help" at all. I am disappointed that the "smart charging" cannot figure out that it cant talk to my Leaf and therefore release the Hypervolt to do its thing and charge my unsupported EV. If its going to be called a "smart" system, it should be able to figure that out. It certainly knows that my EV6 is plugged in, it should be able to tell if an unsupported model of car is plugged in and act accordingly. And Octopus's position that a customer can only have one EV registered to work with a charger is appallingly bad logic.
