Owners who cannot use Nissan Connect (e.g. because it is not offered in their country), or don't want to use it, have a couple of options.

[https://www.openvehicles.com/ OVMS] is an open-source module that can provide all sorts of telematics functionality such as GPS positioning, remote climate control, remote lock/unlock, battery monitoring, etc. In Gen 1 Leafs it can be installed via a simple plug into the OBDII port. In Gen 2 Leafs, a custom adaptor cable can be made to tap into the power and CAN buses at the [[CAN Gateway]].<ref>https://docs.openvehicles.com/en/latest/components/vehicle_nissanleaf/docs/index.html#models-ze1</ref>
