HomeKit support for the Nissan Leaf using hc and my Leaf Go library.
When running, this service publishes a single HomeKit accessory exposing three services:
- A battery service indicating the current charge of your Leaf and its charging status.
- A switch service indicating whether the Leaf is currently charging. If the Leaf is plugged in but not charging, you can flip this switch on to begin charging the vehicle.
- A switch service for the Leaf's climate control. Flipping this switch on starts the vehicle's climate control system.
The Nissan API does not expose climate control status, and it is not possible to disable charging once it has started. As a result, the two switches are stateless and will always reset to the off position. HomeKit does not expose a stateless switch (button) service we can use.
After the vehicle is paired with your iOS Home app, you can control it with any service that integrates with HomeKit, including Siri ("How much battery does the Leaf have?") and Apple Watch. If you have a home hub like an Apple TV or iPad, you can control the Leaf remotely.
The tool can be installed with:
go get -u github.com/joeshaw/leaf-homekit
You will need a configuration file with your Nissan username and password. The format is the same as the config file for the leaf, so you can use it for both tools.
You will need to create a file like ~/.leaf:
username foo@example.com
password carwingsPassw0rd
Then you can run the service:
leaf-homekit -config ~/.leaf
The service will make an initial call to the Nissan service to get the current battery information -- this can take nearly 30 seconds -- before it exposes the accessory to HomeKit.
To pair, open up your Home iOS app, click the + icon, choose "Add Accessory" and then tap "Don't have a Code or Can't Scan?" You should see the Leaf under "Nearby Accessories." Tap that and enter the PIN 00102003 (or whatever you chose in your config file).
Issues and pull requests are welcome. When filing a PR, please make
sure the code has been run through gofmt.
