remote start -> Particle Electron -> internet <- iphone

about this project

I started this project to get remote start working on my car from my iPhone. Much like Viper SmartStart or CompuStar’s Drone Mobile.

current features

• Simple API
  • All calls to the Particle Electron can be done through a REST call. This gives me the option to make anything that has an internet connection a remote.
• iOS Client
  • Screenshots

• Four buttons are supported on the remote
• Status LED
• Temperature sensor

feature wish list

• detect when car is running
• detect door lock/unlock state
• gps
• unlock door when phone is within a few feet of the car

hardware required

• Compustar Remote Start
• Compustar Remote 1WSHR
• Particle Electron https://store.particle.io/#electron
• Device running iOS 7+
• Temperature Sensor TMP36
• Optocoupler (I used a LTV-847)
• Dual color LED (You can use separate LEDs if you like)

You can substitute most of these items for anything that is equivalent.

getting started

• Assemble breadboard

  • Use hardware.fzz or png as a reference
    • Sample
  • Solder leads on switches from remote
  • Attach Particle Electron to breadboard
  • Pins and switches match up to code in arduino

• Setup Particle Electron

  • Follow instructions on (Connecting your Electron)[https://docs.particle.io/guide/getting-started/intro/electron/]
  • (Create a new App)[https://build.particle.io/] at particle.io
  • Paste the code from spark_core/remote-start.cpp to this new App
  • Obtain your device_id and access_token from particle.io

• iOS

  • Install Cocoapods
    • cd carspark/iOS
    • pod install
  • Open Carspark.xcworkspace
  • Build and install device on your iPhone or iPod Touch
  • Add Device ID and Access Token in Settings.app or the 'API Settings' button on the Info screen.

references

Things that will help you learn about how this all works

• Fritzing for reading .fzz files
• Particle Cloud API

api

See remote-start.cpp for more info on what api calls can be used.

Events are sent for every api call that is made and if a connection to Particle Cloud is reestablished.

You can subscribe to events like this.

curl -H "Authorization: Bearer <access_token>" https://api.particle.io/v1/devices/<device_id>/events

warning

This is a project for myself. I am happy to share what I have done but make no guarantee that anyone else attempting this will enjoy the same success, or failures, that I have.
