SmartThings - Ring Alarm

Build Status

📢 This is the version 1 of this application. I have created a newer version which supports Ring Devices. You can find that here - https://github.com/asishrs/smartthings-ringalarmv2

  • 🕐 This setup is going to take 30 minutes to an hour depending on your exposure on the SmartThings app, AWS Lambda, and Java.
  • 💵 Deploying the Bridge Application in AWS as a Lambda is free but you will be charged for the use of API Gateway and Data Transfer. Based on my initial calculation this will less than a dollar per month.

This page explains, how to set up Ring Alarm as a virtual device on your SmartThings. Ring Alarm uses WebSockets to communicate to ring server for checking Alarm Status and Status changes. Unfortunately, SmartThings app does not support WebSockets, and we have to create a bridge application which accepts HTTP calls from SmartThings and communicate to Ring Alarm via WebSockets. Below diagram explains the flow.

SmartThings - Ring Alarm

Note: I have SmartThings classic app, and this approach is tested using that. If you are using new SmartThings app, let me know if this approach requires any changes. PRs are welcome!

If you are still reading this, that means you are ready to invest at least an hour!!!

This setup requires the deployment of two different components.

Bridge Application

As I mentioned before, the bridge application is a proxy between the SmartThings custom app and Ring Alarm. For ease of deployment, I created this as an AWS Lambda function using Java.

You need to install this Lambda in AWS and set up an API gateway to communicate to that. This approach is using the API with Lambda integration using API Gateway. This code also requires an API authentication token. If you are already familiar with setting Lambda with API token, you can skip to the SmartThings Device Handler and Smart App.

Follow the below steps to install and setup Lambda in AWS. You need to have AWS account and the latest Lambda build from here before proceeding to the next step. If you don't have an account, start here

If you want to build the Lambda on your side, you can do that by cloning this repo and then executing ./gradlew build -x test

Get Ring Location Id and ZID

Ring Alarm requires to pass location id and zid of your alarm as part the web sockets call. Though this can achieve via API calls, we don't want to do that as this increases the total number of calls to make before actual web sockets call. You can get those values from the network panel of your browser. Follow below steps to get those.

Location Id
  • Login to Ring Dashboard
  • location ID is shown in the URL: https://app.ring.com/location//dashboard or
  • Login to Ring Dashboard
  • Open your chrome network panel (Option + Command + I in Mac, Ctrl + Shift + I in Windows) and login to Ring Alarm.
  • In the network panel, search for locations.
  • Click on the location API call on the left side.
  • From the right side
ZID
  • Open your chrome network panel (Option + Command + I in Mac, Ctrl + Shift + I in Windows) and login to Ring Alarm.
  • In the network panel, search for socket.io
  • Click on the WebSocket call on the left side.
  • From the right side
    • In the Frames panel, check a frame response with message like "msg":"DeviceInfoDocGetList" (Tip: If you are using chrome browser, you can see a red color down arrow on the left side of message.)
    • Copy that value (Right Click on the mouse and select Copy Message) and paste in your favorite text editor. I prefer an editor like Visual Studio Code as I can format that big message body using JSON format.
    • Search for Ring Alarm on the message and then copy the first zid after Ring Alarm.
    • Save zid for lambda testing and SmartThings Application configuration.

Test Lambda

  • URLs
    • POST /{Invoke URL From Above}/status
    • POST /{Invoke URL From Above}/off
    • POST /{Invoke URL From Above}/home
    • POST /{Invoke URL From Above}/away
  • Sample cURL request
curl -X POST \
  {Invoke URL From Above}/status \
  -H 'x-api-key: your-aws-api-key' \
  -d '{
  "user": "ring username",
  "password" : "ring password",
  "locationId" : "ring location Id",
  "zid" : "ring zid"
}'
