My Tesla Model 3 “Keyfob”

Inspired by a few folks on a few forums online, I took the liberty to extend their idea using a IoT Button, that acts as a simple “keyfob” for the Model 3.

The main goal was being to allow my daughter to lock and unlock the car at home. She is too young to have a phone, and without a more traditional fob, this gets a little annoying. 

I extended the original idea, to understand the different presses (Single, Double, and Long press), and accordingly called the appropriate API to lock the car (single press – think of it as a single click), unlock on a double press, and open the charge port on a long press (when one presses and holds the button 2-3 secs).

For those who aren’t aware, the Amazon IoT buttons calls a Lambda function on AWS and plugging into that, one can extend this. The button needs to be connected, and online for this to work, and in my case, it is on the home wifi network. 

Update: Many of you asked on how to set this up for yourself; I got around to blogging all the step on that; you can read those here.

This blog is my personal blog and while it does reflect my experiences in my professional life, this is just my thoughts. Most of the entries are technical though sometimes they can vary from the wacky to even political – however that is quite rare. Quite often, I have been asked what’s up with the “gibberish” and the funny title of the blog? Some people even going the extra step to say that, this is a virus that infected their system (ahem) well. [:D] It actually is quite simple, and if you have still not figured out then check out this link – whats in a name?
