Homebridge TTLock Plugin

A Homebridge TTLock plugin that allows you to access your TTLock Device(s) from HomeKit with Homebridge.

Requirements

Lock/door handle using TTLock Platform (Wifi, or Bluetooth + Gateway)
If using Bluetooth - TTLock Compatible Gateway (G1, G2, G3, or G4). Successfully tested with this one
TTLock app for iOS or Android
Bash access to run curl command

Setup Instructions

Create TTLock Developer Account

Go to TTLock Platform Registration.
Complete the required information to create a developer account for API access.
Wait for the email confirming activation of your account (manual process that will be completed by TTLock).
Log back into the TTLock Developer Platform and retreive your ClientId and ClientSecret.

Create a New User on Developer Account

Make up a new username. Creating a new user account is required! It must be associated with your developer account (unfortunately you can't use an account you've already set up on the TTLock app).
Come up with a password and save it somewhere. When you submit the request to create the new user, you'll have to submit the password as md5 (use this site).
Using a terminal, run this command to create the new user on your developer account:

curl --location --request POST 'https://euapi.ttlock.com/v3/user/register?clientId=[clientid]&clientSecret=[clientsecret]&username=[username]&password=[passwordasmd5]&date=CURRENTMILLIS' \
--header 'Content-Type: application/x-www-form-urlencoded' \

In the response to the request, note the username that is assigned (it will be your username prefixed with some random characters). This will be the username you'll use to log into the mobile app and the Homebridge plugin from now on.

Associate Lock and Gateway with New Account

Log into the TTLock iOS or Android app with your new account. You'll use the username that the API call returned, and the password you created (NOT as md5).
Add your lock(s) to the app to accociate them with your account. If you have previously used the lock with the app, you'll have to reset and add it to the new account.
If using Bluetooth, add the gateway (and ensure it is associated with the locks).
Important -In the settings for each lock, ensure the Remote Unlock setting is set to On.
