Node-RED

If you boot up our tech stack using docker-compose you already have a Node-RED instance running on your local machine.

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):

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, hook it up to a gauge and display it on a dasboard.

The dashboard looks like that.

You can see this flow also in this repository.
