On a unix box ...

Check you have node & npm installed node -v. If not then you'll need nodejs from nodejs.org

git clone https://github.com/mitra42/frugal-iot-server.git
cd frugal-iot-server
npm install
npm update # To make sure you have the latest version of the client since it comes from github

edit config.yaml

in config.d put a yaml file for your organization

• the repo has an example for dev which is the developers.

node frugal-iot-server.js

If its working correctly you should see something like

readYamlConfigFile ./config.yaml
... and then reading each of the other files

Config= {
  server: { port: 8080 },
  mqtt: { broker: 'wss://frugaliot.naturalinnovation.org/wss' },
  organizations: { 
    dev: { mqtt_password: 'public', projects: [Array] } 
  }
}

Where the config is reported back, then it successfully connects to the mqtt server and receives data from nodes attached to it.

Open a browser pointing at for example localhost:8080 and you should see the UI.

To set it up as a service that runs at startup (and instructions vary between flavors of Linux)

copy and edit frugaliot.service to /usr/lib/systemd/system/frugaliot.service you'll need to change the user and the place where its cloned and possibly the location of node

You can runservice frugaliot start to start it and systemctl enable frugaliot to make sure it starts at boot.

Note that this will give you a HTTP server, but OTA on ESP32 requires HTTPS.

The easiest way to do this is to put it behind a reverse proxy like nginx or apache. Feel free to reach out if you do not know how to do this.
