How to Connect Your VinFast Car With Home Assistant?

Why Connect Your VinFast Car With Home Assistant?

If you own a VinFast electric vehicle (VF e34, VF 3, VF 5, VF 6, VF 7, VF 8, or VF 9) and are also a fan of home automation, you may have wished to:

• Monitor the car’s status in real time right on your smart home dashboard
• Receive automatic alerts when tire pressure is low or the battery is nearly empty
• View parameters that are hidden by the official VinFast app (especially on older models)
• Integrate with other automations (for example: turn on the car’s AC before leaving the house)

This article will guide you step by step to turn that dream into reality.

What You Will Achieve

After completing this guide, you will have:

✅ A car monitoring dashboard displaying:
- Battery level and remaining range
- Charging status
- ODO (total distance traveled)
- Tire pressure of all 4 wheels
- Cabin temperature
- Door/lock/trunk/hood status

✅ Smart automations:
- Alerts when tire pressure < 30 PSI
- Notifications when battery is below 20%
- Automatically turn on the car’s AC before going to work

✅ Access to hidden parameters that the VinFast app does not display

Requirements Before You Start

Hardware

• Home Assistant already installed and running (Raspberry Pi, Mini PC, or VM)
• A supported VinFast electric vehicle
• An activated VinFast account that can log into the app

Basic Knowledge

• Know how to access Home Assistant via a web browser
• Be able to copy/paste commands into the terminal (step-by-step guidance provided)

No coding required – everything comes with automated scripts!

Part 1: Install the VinFast Plugin

Step 1.1: Install HACS (Home Assistant Community Store)

HACS is the "app store" for Home Assistant, helping you install community plugins easily.

If You Don’t Have HACS Yet:

1. Install the Terminal & SSH add-on:
2. Go to Settings → Add-ons → Add-on Store
3. Search for "Terminal & SSH", click Install → Start
4. (Tip: Enable "Show in sidebar" for easier access)
5. Create a GitHub account (if you don’t have one):
6. Visit github.com/join and sign up for free
7. Install HACS:
8. Open the Terminal you just installed in step 1
9. Copy and paste the following command:
   bash wget -O - https://get.hacs.xyz | bash
10. Wait for it to finish (about 1–2 minutes)
11. Restart Home Assistant: Settings → System → Restart
12. Activate HACS:
13. After restarting, go to Settings → Devices & Services → Add Integration
14. Search for "HACS" and click on it
15. Tick all the confirmation boxes → Submit
16. Copy the code shown
17. Click the GitHub link → Log in → Authorize HACS
18. Done! (If you don’t see HACS in the sidebar, try clearing your browser cache)

Step 1.2: Install the VinFast Plugin via HACS

1. Open HACS from the sidebar
2. Select the Integrations tab
3. Click the 3-dot icon (top right corner) → Custom repositories
4. In the popup window:
- Repository: Paste the link https://github.com/leolionart/vinfast
- Category: Select Integration
- Click Add
5. Now search for "VinFast Connected Car" in the HACS list
6. Click Download → Download again to confirm
7. Restart Home Assistant once more

Step 1.3: Configure the VinFast Integration

1. Go to Settings → Devices & Services
2. Click + Add Integration (bottom right)
3. Search for "VinFast"
4. Enter the following information:
5. Email: Your VinFast account email
6. Password: Your password
7. Region: Select your region (usually Vietnam)
8. Click Submit

Note: Logging in here will log your account out of the VinFast app on your phone, so use a secondary driver account to avoid inconvenience.

If the information is correct, your car will appear as a new device!

Part 2: Build a Car Monitoring Dashboard

Now comes the fun part – creating an intuitive interface to monitor your car.

Step 2.1: Install Required Custom Cards

A beautiful dashboard requires these 3 custom cards:

1. Open HACS → Frontend tab
2. Click + Explore & Download Repositories
3. Search for and install, one by one:
4. button-card
5. layout-card
6. card-mod
7. Restart Home Assistant

Step 2.2: Run the Automatic Dashboard Generator

The VinFast plugin comes with a smart script to automatically create a dashboard for you.

1. Open Terminal (from the sidebar)
2. Navigate to the plugin folder:
bash cd /config/custom_components/vinfast
3. Run the script:
bash python3 setup_dashboard.py
4. Answer the questions:
- Entity Prefix: Enter the entity prefix of your car (for example: if you see sensor.vf8_battery, type vf8)
- Choice:
- Type 1 for Full Wall Panel (full-screen dashboard with a beautiful glassmorphism style)
- Type 2 for Simple Card (a compact card to add to your existing dashboard)

1. The script will create a YAML file (for example: my_vinfast_dashboard.yaml)

Step 2.3: Add It to Home Assistant

With Simple Card:

1. Install the File Editor add-on (from the Add-on Store) to easily open files
2. Open the generated YAML file and copy all its contents
3. Go to your Dashboard → Edit Dashboard → Add Card
4. Scroll down and select Manual
5. Paste the contents in → Save

With Full Wall Panel:

1. Go to Dashboard → Edit Dashboard → 3-dot icon → Raw Configuration Editor
2. Paste the YAML file contents there (or create a new View of type "Panel")

Result: You’ll see a dashboard fully displaying:
- Battery level and remaining percentage
- Drivable range (km)
- Charging status (charging/not charging)
- Total ODO
- Tire pressure of all 4 wheels
- Cabin temperature
- Icons for doors/locks/trunk/hood (open/closed)

Part 3: Set Up Smart Automations

Now we’ll create automations so the car can "automatically report" when there’s an issue.

Automation 1: Low Tire Pressure Alert

Low tire pressure is a leading cause of danger and higher energy consumption. Let Home Assistant monitor it for you.

1. Go to Settings → Automations & Scenes → Create Automation
2. Select Start with an empty automation
3. Configure as follows:

Trigger:
- Click Add Trigger → Numeric state
- Entity: sensor.vf8_tire_pressure_front_left (replace vf8 with your prefix)
- Below: 30 (PSI)
- For: 5 minutes (to avoid false alerts due to temporary fluctuations)

Action:
- Click Add Action → Notify
- Choose the notify service (for example: notify.mobile_app_iphone)
- Message:
⚠️ Warning: The front left tire of {{ state_attr('sensor.vf8_device_name', 'friendly_name') }} has low pressure ({{ states('sensor.vf8_tire_pressure_front_left') }} PSI). Please check it!

1. Repeat for the other 3 tires (front_right, rear_left, rear_right)

Automation 2: Remind to Charge When You Get Home

Automatically remind you to plug in the charger if the battery is below 30% when you arrive home.

Trigger:
- Device: Your phone enters the Home zone

Condition:
- Entity: sensor.vf8_battery
- State: below 30

Action:
- Notify:
🔋 Your car battery is at only {{ states('sensor.vf8_battery') }}%. Don’t forget to plug in the charger!

Automation 3: Turn On the AC Before Going to Work

(Requires that the car is already paired with Home Assistant – see Troubleshooting section)

Trigger:
- Time: 7:00 AM (Monday – Friday)

Condition:
- Outdoor temperature > 28°C (optional)

Action:
- Service: switch.turn_on
- Target: switch.vf8_air_conditioning
