Install Node-RED

To get started you need to install Node-RED and add the TTN node 

There is some great documentation on this at the LEARN platform.

Install InfluxDB and create a database

InfluxDB is an open source database written in Go specifically to handle time series data with high availability and high performance requirements. InfluxDB installs in minutes without external dependencies, yet is flexible and scalable enough for complex deployments.

Install InfluxDB

For MAC OS X (via Homebrew). Open up the terminal and run:

brew update 
brew install influxdb

To start InfluxDB at login, run:

brew services start influxdb

If you use another operating system, have a look here.

Creating a database

Well done, you've installed InfluxDB locally. The `influx` command should now be available via the command line.

If you type in `influx` and displays something like the lines below, you're all set.

Connected to http://localhost:8086 version v1.2.0
InfluxDB shell version: v1.2.0

The next step is thinking of a fancy name for a database, like `ttndb`. 

CREATE DATABASE ttndb

To start using this database, mention it explicitly. The `USE <db-name>` command automatically set the database for all future requests.

USE ttndb

Well done. You've now setup InfluxDB and created a database.

Setup InfluxDB node on Node-Red

Open Node-Red (which is probably located at `http://localhost:1880`)

Open the menu of Node-RED by clicking on the icon  

Select `Manage palette`  and click on the tab `Install` and search for `Influx`. It should look something like this:

Setup the InfluxDB node.

Drag the InfluxDB node to the Node-RED environment.

Configure the node, it should look something like the image below. Use the name of the Database that you just have created.

Link the node `TTN Message` to the `InfluxDB` node.

Install Grafana

Grafana is an open source metric analytics & visualization suite. It is most commonly used for visualizing time series data for infrastructure and application analytics but many use it in other domains including industrial sensors, home automation, weather, and process control.

For MAC OS X, you can use the following command to install Grafana.

If you use another operating system, have a look here.

brew update
brew install grafana

Start Grafana by running:

brew services restart grafana

Open up Grafana on: `http://localhost:3000/` and use `admin` `admin` to login.
