# Tesla + WizFi360 home automation IOT device

> IoT device that works with Tesla car

Original author: Jonghyeok Kim

## Components

- **Arduino Due** x 1: Controller for MQTT and IR remote ([docs](https://www.farnell.com/datasheets/1682211.pdf))
- **WIZnet WizFi360-EVB-Mini** x 1: MQTT subscription ([docs](https://docs.wiznet.io/Product/Wi-Fi-Module/WizFi360/wizfi360_evb_mini))
- **Raspberry Pi 4 Model B** x 1: Server ([docs](https://datasheets.raspberrypi.com/rpi4/raspberry-pi-4-product-brief.pdf))

## Article

These days there're more and more smart devices such as IoT devices at home and smart cars.

I'm currently owning a Tesla car and I integrated my own server to collect data from my car. Raspberry pi is a good small server for the purpose.

There's a tool called Teslamate to do this job. Teslamate can be used as a MQTT broker and it publishes some good information that we can integrate with WizFi360.

I thought this combination could be very useful to automate my home devices. So I decided to do this project.

### System

1) Raspberry pi + Teslamate

- Teslamate runs on raspbian(Raspberry pi linux) and collects car data in real time

- Role as MQTT broker

2) Arduino due + WizFi360 + IR transceiver

- Arduino due + WizFi360 subscribes Teslamate MQTT topics

- Whenever I come to home with my car then MQTT topic 'home_geo' will be flaged
  - I made geo fence of home called 'home_geo'

### Scenario

![](https://maker.wiznet.io/upload/ckeditor5/797179554%5F1667215468%2Epng)

- Additionally many other car information can be subscribed
  - such as charging status, tire pressure, battery status
  - <https://docs.teslamate.org/docs/integrations/mqtt>

### Test results

1. MQTT broker operation test

Teslamate 'home_geo' setting

#### Test drive to drive towards home

- Check MQTT subscription with mac

- To check if 'home_geo' flag runs on MQTT broker(raspberry pi + Teslamate)

- As you can see below 'home_geo' flagged

Test with WizFi360 to subscribe MQTT topic

2. WizFi360 AT command test with Arduino Due

3. Arduino Due + IR transmitter test

- Read IR remote signal

- Transmit IR remote raw data

### How to implement

1. MQTT broker setup(Raspberry pi + Teslamate)

1) Prepare Raspberry pi 4 with raspbian os

- <https://www.raspberrypi.com/software/>

2) Install Teslamate in Raspberry pi

- <https://docs.teslamate.org/docs/installation/docker>

- Setup MQTT
  - MQTT broker will be running after installing Teslamate
  - MQTT username and password need to be set
    - Add 'MQTT_USERNAME' and 'MQTT_PASSWORD' value in 'docker-compose.yml' file

```xml
docker-compose.yml

version: "3"

services:
  teslamate:
    image: teslamate/teslamate:latest
    restart: always
    environment:
      - ENCRYPTION_KEY= #insert a secure key to encrypt your Tesla API tokens
      - DATABASE_USER=teslamate
      - DATABASE_PASS= #insert your secure database password!
      - DATABASE_NAME=teslamate
      - DATABASE_HOST=database
      - MQTT_HOST=mosquitto
      - MQTT_USERNAME="admin"
      - MQTT_PASSWORD="password"
    ports:
      - 4000:4000
    volumes:
      - ./import:/opt/app/import
    cap_drop:
      - all
      ...
```

2. IR remote controller(Arduino Due + IR remote)

- IR remote library for Arduino Due used

- <https://github.com/enternoescape/Arduino-IRremote-Due>

3. MQTT subscribe(Arduino Due + WizFi360)

- Send AT commands below to WizFi360(RX1, TX1)

```plaintext
AT+CWMODE_CUR=1
AT+CWJAP_CUR="<WiFi AP>","<WiFi password>"

AT+MQTTSET="admin","password","wiznet",60 
AT+MQTTTOPIC="","teslamate/cars/1/geo_fence"
AT+MQTTCON=0,"<raspberry pi IP address>",1883
```
