Renault-Zoe-API

A basic API for getting information about your Renault Zoe Electric Vehicle. Read the original blog post.

Please Note! I no longer have a Renault Zoe, so I am unable to keep this API updated. You are welcome to discuss issues with it in the "issues" tab.

All these API calls can be found by using the Renault ZE Services website. I am indebted to this German blog post for kicking off this work. I'd also like to thank Renault for their "esoteric" use of JavaScript!

What's Available?

This API is fairly limited, here's what you can do with it:

See battery status, range, charging status.
Start preconditioning
See preconditioning history
See and set charging schedule.
See charging history

Getting started

First, register with Renault ZE Services. This will give you a username and password.

Secondly, you'll need to get your VIN and API token. This can be obtained by posting the username and password to Renault. For example:

curl \
   -H "Content-Type: application/json" \
   -X POST \
   -d '{"username":"you@example.com","password":"P4ssw0rd"}' \
   https://www.services.renault-ze.com/api/user/login`

This will get you back some JSON with your API tokens. Here's an example:

{
	"token": "AAAA",
	"refresh_token": "BBBB",
	"user": {
		"id": "CCCC",
		"locale": "en_GB",
		"country": "GB",
		"timezone": "Europe/London",
		"email": "you@example.com",
		"first_name": "Terence",
		"last_name": "Eden",
		"phone_number": "+447700900123",
		"vehicle_details": {
			"timezone": "Europe/London",
			"VIN": "VVVV",
			"activation_code": "GGGG",
			"phone_number": "+447700900123"
		},
		"scopes": ["BATTERY_CHARGE_STATUS", 
				   "BATTERY_CHARGE_HISTORY", 
				   "BATTERY_CHARGE_REMOTE_ACTIVATION", 
				   "BATTERY_CHARGE_SCHEDULING", 
				   "AC_REMOTE_CONTROL", 
				   "BATTERY_CHARGE_LOWALERT"],
		"active_account": "DDDD",
		"associated_vehicles": [{
			"VIN": "VVVV",
			"activation_code": "GGGG",
			"user_id": "XXXX"
		}],
		"gdc_uid": "YYYY"
	}
}

Battery Status

Let's start with the battery. We need to use your token and VIN from above.

curl \
   -H "Authorization: Bearer AAAA" \
   "https://www.services.renault-ze.com/api/vehicle/VVVV/battery"

This gets us:

{
	"charging": false,
	"plugged": true,
	"charge_level": 100,
	"remaining_range": 124.0,
	"last_update": 1476472742000,
	"charging_point": "INVALID",
	"remaining_time": 750
}

A few point to note. The remaining_range is in Kilometres. The last_update is a Unix timestamp. The remaining_time is in minutes. The charging_point is available only when plugged is true. The remaining_time is available only when charging is true.

Preconditioning

The Zoe can be set to warm-up or cool down depending on the last temperate you set in the car. It will also blast the front window de-mister. The process takes five minutes, so you can set it shortly before you need to set off. Preconditioning will only work when the car's battery is above 45%.

Precondition Now

curl \
   -X POST \
   -H 'Content-Type: application/json' \
   -H "Authorization: Bearer AAAA" \
   "https://www.services.renault-ze.com/api/vehicle/VVVV/air-conditioning"

This command does not return any value. There is also no way to cancel the command remotely - you have to physically enter the car and turn it off.

Precondition Later

If you know that you want to leave at a specific time, you can set the car to precondition at a set time.

curl \
   -H "Authorization: Bearer AAAA" \
   -H 'Content-Type: application/json;charset=UTF-8' \
   --data-binary '{"start":"1753"}' \
   'https://www.services.renault-ze.com/api/vehicle/VVVV/air-conditioning/scheduler'

As far as I can tell, the start time is when you want the conditioning to start - not when you want it to be finished.

There is no way to cancel a precondition.

Preconditioning Last Status

Want to see if the preconditioning message was received by the car correctly?

curl \
   -H "Authorization: Bearer AAAA" \
   "https://www.services.renault-ze.com/api/vehicle/VVVV/air-conditioning/last"

This returns information about who or what sent the request:

{
	"date": 1476538293000,
	"type": "USER_REQUEST",
	"result": "SUCCESS"
}

Preconditioning History

You can also see how often your car has been preconditioned.

curl \
   -H "Authorization: Bearer AAAA" \
   https://www.services.renault-ze.com/api/vehicle/VVVV/air-conditioning?begin=1016&end=1016

[{
	"date": 1476165377000,
	"type": "USER_REQUEST",
	"result": "ERROR"
}, {
	"date": 1476079325000,
	"type": "CAR_NOTIFICATION",
	"result": "ERROR"
}, {
	"date": 1476079270000,
	"type": "USER_REQUEST",
	"result": "SUCCESS"
}, {
	"date": 1476079266000,
	"type": "CAR_NOTIFICATION",
	"result": "SUCCESS"
}]

Start Charging

You may have set your Zoe only to charge at specific times - perhaps to take advantage of cheap rate electricity. You can override this by issuing the charge command.

curl \
   -X POST \
   -H 'Content-Type: application/json' \
   -H "Authorization: Bearer AAAA" \
   https://www.services.renault-ze.com/api/vehicle/VVVV/charge

Again, this won't return a response. If your battery cannot be charged, you'll be notified via email or SMS depending on the preference you set up when you registered.

Charging History

curl \
   -H "Authorization: Bearer AAAA" \
   https://www.services.renault-ze.com/api/vehicle/VVVV/charge/history?begin=1016&end=1016

The begin and end take MMYY as their arguments. That is, if you want October 2016 you need to use 1016.

This returns an array, the most recent charging session at the top.

[{
	"date": 1476538527000,
	"type": "START_NOTIFICATION",
	"charging_point": "SLOW",
	"charge_level": 99,
	"remaining_autonomy": 119
}, {
	"date": 1476472727000,
	"type": "END_NOTIFICATION",
	"charging_point": "INVALID",
	"charge_level": 100,
	"remaining_autonomy": 124
}, {
	"date": 1476462129000,
	"type": "START_NOTIFICATION",
	"charging_point": "ACCELERATED",
	"charge_level": 34,
	"remaining_autonomy": 42,
	"remaining_time": 10500000
}]

The remaining_autonomy is, again, the range in Km. The remaining time is expressed in milliseconds. So 10500000 is the equivalent of 2 hours and 55 minutes.

Notifications

You can use the website to set up notifications. For example, if there is a problem with your charge, Renault will send you an SMS. This API call lets you see what notifications you have set up.

Set Notifications

curl \
   -H "Authorization: Bearer AAAA" \
   -X PUT \
   -H 'Content-Type: application/json;charset=UTF-8' \
   --data-binary '{"battery_status":"EMAIL","charge_start":"SMS","charge_end":"SMS","charge_problem":"SMS","low_battery":"SMS","low_battery_reminder":"SMS","do_not_disturb":null}' \
   'https://www.services.renault-ze.com/api/vehicle/VVVV/settings/notification'

You can change any of the options with EMAIL or SMS.

You can set a "do not disturb" option. This will suppress all notifications during specific times. Sadly, this is a fairly blunt instrument - you can only set one time which then is enforced every day.

In the above example, change "do_not_disturb":null to

"do_not_disturb":{"start":"1710","end":"1811"}}'

This will give you peace between 5:10pm and 6:11pm.

See Notifications

You can use the website to set up notifications. For example, if there is a problem with your charge, Renault will send you an SMS. This API call lets you see what notifications you have set up.

curl \
   -H "Authorization: Bearer AAAA" \
   https://www.services.renault-ze.com/api/vehicle/VVVV/settings/notification

This returns:

{
	"battery_status": "EMAIL",
	"charge_start": "NONE",
	"charge_end": "SMS",
	"charge_problem": "SMS",
	"low_battery": "SMS",
	"low_battery_reminder": "SMS",
	"do_not_disturb": null
}

Charging Times

The Zoe's charging calendar is, sadly, crap. You can say "charge between these times" but you can only have one schedule per day. So if you only want the car to charge between 0300-0700 and 1800-2200 on Mondays - you're out of luck.

It also seemed to force me to set a schedule for every day.

This is a multi-stage process.

Create a schedule

In this example, I'm setting the charging to be active on Monday from 0100 for 1 hour and 15 minutes. All other days start at different times, but last only for 15 minutes. All start times must be at 00, 15, 30, 45 minutes. All durations must be in increments of 15 minutes.

curl \
   -H 'Authorization: Bearer AAAA' \
   -X PUT \
   --data-binary '{"optimized_charge":false,"mon":{"start":"0100","duration":"0115"},"tue":{"start":"0200","duration":"0015"},"wed":{"start":"0300","duration":"0015"},"thu":{"start":"1600","duration":"0015"},"fri":{"start":"1900","duration":"0015"},"sat":{"start":"1400","duration":"0015"},"sun":{"start":"1200","duration":"0015"}}' \
   'https://www.services.renault-ze.com/api/vehicle/VVVV/charge/scheduler/offboard'

View the schedule

Let's make sure the schedule has been sent correctly

curl \
   -H 'Authorization: Bearer AAAA' \
   'https://www.services.renault-ze.com/api/vehicle/VVVV/charge/scheduler/onboard'

Returned - hopefully! - is the schedule:

{
	"enabled": false,
	"schedule": {
		"mon": {
			"start": "0100",
			"duration": "0115"
		},
		"tue": {
			"start": "0200",
			"duration": "0015"
		},
		"wed": {
			"start": "0300",
			"duration": "0015"
		},
		"thu": {
			"start": "1600",
			"duration": "0015"
		},
		"fri": {
			"start": "1900",
			"duration": "0015"
		},
		"sat": {
			"start": "1400",
			"duration": "0015"
		},
		"sun": {
			"start": "1200",
			"duration": "0015"
		}
	}
}

Deploy the schedule

Be default, the schedule isn't activated. It needs to be "deployed" in order to send it to the car.

curl \
   -H 'Authorization: Bearer AAAA' \
   -X POST \
   'https://www.services.renault-ze.com/api/vehicle/VVVV/charge/scheduler/offboard/deploy'

Deactivate the schedule

If you deactivate the schedule then the car will charge whenever it is plugged in.

curl \
   -H 'Authorization: Bearer AAAA' \
   -X PUT \
   --data-binary '{"enabled":false}' \
   'https://www.services.renault-ze.com/api/vehicle/VVVV/charge/scheduler/onboard'

Refreshing the authorization token after expiry

Refreshing a token can be done easily and without username or password. You need your expired token as well as the refresh_token that was issued at login.

curl \
   -X POST \
   -H 'Authorization: Bearer eyJAAA.eyJBBB.CCC' \
   -d '{"token":"eyJAAA.eyJBBB.CCC","refresh_token":"DDDD"}' \
   'https://www.services.renault-ze.com/api/user/token/refresh'

The answer is an updated token:

{"token":"eyJDDD.eyJEEE.FFF"}

Note that the refresh will work multiple times using the same refresh_token, so keep that one at hand.

How do I know if my token expired?

The token itself contains this information. It is in JSON Web Token format, i.e. it consists of three parts, each separated by a period. The middle part (called the payload) is a base64-encoded JSON text which contains the following fields:

{
  "sub": "myzelogin@example.com",
  "jti": "1111222233334444aaaabbbbccccdddd",
  "iat": 1527613751,
  "exp": 1527649751
}

The exp field is the UNIX timestamp of the token expiry. The refreshed token will have the same sub and jti values.

That's all folks?

There are a few other API calls - mostly around registering and removing vehicles, and updating personal details.

What's Missing?

Sadly, the Renault API is quite poor compared to BMW's API. Here's what I'd love to see:

Vehicle status - doors locked, headlights on.
Efficiency - last journey, total.
Mileage (although available in MY Renault API, so included in this script).
Physical location.
