smarthings_exporter

Smartthings_exporter is a command line tool to export information about your SmartThings sensors in a format that can be scraped by Prometheus. The tool talks to the SmartThings API and collects sensor data which is exposed as metrics over http.

Installation

The installation instructions assume a properly installed and configured Go development environment. The very first step is to download and build Smartthings_exporter (this step will also download and compile the GoSmart library):

$ go get -u github.com/kadaan/smartthings_exporter

SmartThings Setup

Before you can use Smartthings_exporter, you need to register it with SmartThings.

The first step is to setup the API that Smartthings_exporter uses to communicate with SmartThings. To do this you need to:

1. Navigate to the SmartThings API website. Register a new account (or login if you already have an account).
2. Once logged in, click on My SmartApps. This will show a list of the current SmartApps installed (it could be blank for new accounts).
3. Click the Settings button at the top right.
4. Click the Add new repository link at the bottom of the settings dialog box.
5. In the new row fill in:
   1. Owner: kadaan
   2. Name: smartthings_exporter
   3. Branch: master
6. Press Save
7. Click Update from Repo at the top right
8. Choose smartthings_exporter (master)
9. Under the New list on the right check smartapps/kadaan/smartthings-exporter-api.src/smartthings-exporter-api.groovy
10. Check Publish at the bottom
11. Click Execute Update
12. Click the Edit Properties button for the kadaan : Smartthings Exporter API entry
13. Click OAuth
14. Click Enable OAuth in SmartApp
15. In Redirect URI, enter http://localhost:4567/OAuthCallback. Case is important here
16. Click Update
17. Click OAuth
18. Take note of the Client ID and Client Secret. These will be used to authenticate and retrieve a token. Once the token is saved locally by the library, authentication can proceed without user intervention.

Smartthings_exporter configuration

We now need to register Smartthings_exporter to with your SmartThings app.

Run:

$ smartthings_exporter register --smartthings.oauth-client=[client_id] > .st_token

Follow the prompts to authorize the app.

Running

Now we can start Smartthings_exporter by running:

$ smartthings_exporter --smartthings.oauth-client=[client_id] --smartthings.oauth-token.file=.st_token
