Today in #ThingsIWishExisted: August Smart Lock API

I bought an August Smart Lock three years ago so I could stop carrying around door keys and have my doors magically unlock themselves. Actually that’s not really true, I really bought a crowdfunded Lockitron three years ago but the dang thing was going to be so delayed I impulse bought the August lock while in an Apple store. I later rationalized the purchase thinking that I’d compare it to the Lockitron when it eventually arrived, and return one of them. It ended up being OVER THREE YEARS before the Lockitron finally showed up, and by that time I’d moved out of my apartment in Boston to Texas where my new place had a door that no longer fit the Lockitron.

Long story short, I’ve been using the August lock for a while. The thing that sucks about it is that the August Auto-Unlock feature is pretty crappy. The dream is that I walk up to the door, it magically unlocks itself and I open it and stride through like a man from the future. The reality is that I do that about 25% of the time, I stand awkwardly in front of the door waiting for it to eventually open 50% of the time, and 25% of the time it never opens and I sigh and use the Android app to unlock the door (or I use the key I never stopped carrying). First world problems, right?

This wouldn’t be too much of a problem if August would create an Android Wear app for my smartwatch, so I could quickly just tap my wrist while walking up to the door to unlock it instead of fishing my phone out of my pockets, unlocking it, opening the app, waiting for it to start up and then tapping my house icon and waiting and then tapping the unlock button. Terrible! But they haven’t made an Android Wear app probably because there aren’t enough people willing to look like nerds and wear Android watches to justify the expense. Well, that’s fine, I could just write my own Android Wear app, but I’d need access to the August Smart Lock API and they don’t make it public. What’s the point of having a Smart Lock if the smart features aren’t available for tinkerers to tinker with? So frustrating.

A smart guy reverse engineered the bluetooth protocol and released a NodeJs program that could run on a Raspberry Pi to open the August lock, but running Wifi, Bluetooth and NodeJs on a Raspberry Pi was asking for trouble, and my setup crashed often enough to fail the WAT¹. I ended up creating a horribly complicated system derived from the Node library which now involves an old phone, a Microsoft Azure Function and Google Firebase notifications to work with my old Geolocation Watch App to unlock the door. It’s working for now, so we’ll see if it ends up being reliable enough to pass the WAT.

UPDATE 3/18/2017: It ended up being too slow and unreliable so I ported the August bluetooth API to Xamarin (and made a plugin) so I could build this functionality into my Zones app. Works much better.

Oh, and the Lockitron that arrived 3 years late and doesn’t fit my door? It has a public API.
