I have a Tesla Wall Connector fitted in 2016 which I fear might need replacing due to problems connecting well to my (new to me) 2020 Model 3. I'm in the UK and on the Intelligent Octopus tariff and also have a Tesla Powerwall. If I have to replace the Wall Connector, should I get the latest Wall Connector from Tesla or consider an Ohme or other Intelligent Octopus compatible charger instead? I'm thinking about Ohme because my next EV might well not be a Tesla and I want to be free to choose without worrying about car compatability with Octopus. But is trying to use Ohme with my Model 3 and Intelligent Octopus going to be a lot of trouble / hassle? I just want an easy life where things work without many hours of research and troubleshooting.... Any advice much appreciated.
