# Node-RED
|
|
|
|
If you boot up our tech stack using `docker-compose` you already have a Node-RED instance running on [your local machine](http://localhost:1880/).
|
|
|
|
## First steps
|
|
|
|
For debuging I am going to install Node-RED's own dashboard.
|
|
|
|
Shell into your Docker container.
|
|
|
|
|
|
|
|
Inside the container you can install the Node-RED Dashboard (we will switch to Grafana, soon):
|
|
|
|
```sh
|
|
npm install node-red-dashboard
|
|
```
|
|
|
|
The dashboard should be visible on the righmost menu item in Node-RED.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
In Node-RED you can add a MQQT node to receive values from the power monitor.
|
|
|
|
|
|
|
|
To simply display the values in a gauge (or chart) you can hook it up to a gauge node.
|
|
|
|
|
|
|
|
In the dasboard section you have to create a tab. Inside this tab you have to create a group.
|
|
|
|
|
|
|
|
The tricky part is putting the gauges in the group. This is done in the gauge's settings (not in the dashboard's settings).
|
|
|
|
|
|
|
|
You can view the dashboard in an (also mobile) web browser.
|
|
|

Have a look at the flow also in [this repository](./00-dashboard-example/dashboard.json). |
