I've been having issues now for a couple of weeks with IO reconising the car and charging. If I disconnect the car, then reconnect, it seems to work for a day or two, then tells me it can't connect to the car and asks to renew the connection. The last communication I had from Octopus was to disengage smart charging, and wait for a fix from them, which still hasn't come.
Could this be a car/wifi connectivity issue?
