# 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 shell into your Docker container and install the Node-RED Dashboard (we will switch to Grafana, soon):
```sh
npm install node-red-dashboard
```
Then the dashboard should be visible on the righmost menu item in Node-RED.

Then you can add a MQQT node to receive values from the power monitor, hook it up to a gauge and display it in a dasboard.

The dashboard looks like that.
