This application is a proxy between Slack and the LaMetric Time. It allows you to send messages from a Slack channel and have it display on a LaMetric Time device.
- A Slack account (https://slack.com)
- A LaMetric Time (https://lametric.com/)
- A LaMetric Developer Account (https://developer.lametric.com)
- Visual Studio 2015 (https://www.visualstudio.com)
Assuming you're familiar with Slack, setup is fairly straightforward. Essentially all you have to do is create a new Slash Command integration, configure it how you'd like, and tell it to send a POST to the URL where you have this application deployed (See Local Testing Tips for localhost configuration).
This part is a little bit more involved. As the LaMetric API does not currently allow each installation to have it's own unique id, you basically need a unique LaMetric application for each of your LaMetric Time devices. So, to get this side setup, create a new application and:
- Set the Application Type to PUSH
- Give your app a cool looking Slack icon (available in the icon selection)
- Setup the default text to be something simple, such as "READY"
- Save and publish the new application
- Go to your phone and install the application from the LaMetric store onto your device
There's not much you have to do here. In the Web.config file in the Web Application project, there will be two application settings for lametric:url and lametric:token. Simply take the Push URL and Access Token from the LaMetric application you created earlier and put them in here. After that, the application is configured and ready to go!
When running this application within a local testing environment using Visual Studio and IIS Express, you'll need to give Slack the ability to send messages to the application, which might be hard if you're behind a firewall. Also, IIS Express doesn't like to talk to the outside world, so you'll need to run Visual Studio as an Administrator when testing this locally as well, as I configured this application to listen on all host names when running locally.
To provide Slack access to your local IIS Express instance, I recommend ngrok (https://ngrok.com/), which makes the process extremely simple. All you have to do is download the application and run ngrok http 51980.
