micro-app-simple-dashboard - MQTT/Node base home dashsboard

Micro app to display a home dashboard showing temperature, power usage and other data collected from local sensors. The dashboard is updated in realtime using socket.io

The dashboards listens on a number of mqtt topics for updates and then forwards the updates to clients using socket.io. It provides a simple way to display iot sensor data on a client.

This is an example display:

The following projects can be used to connect sensors temperature sensors and power sensors

• PI433WirelessRecvMananager

Usage

After installation modify ../lib/config.json to match your configuration

The configuration entries that must be updated include:

• mqttServerUrl - url of the mqtt server to connect to. This can either start with tcp:// or mqtts://. If it starts with mqtts:// there must be a subdirectory in the lib directory called mqttclient which contains ca.cert, client.cert, client.key which contain the key and associated certificates for a client which is authorized to connect to the mqtt server.
• dashboardEntries - array in which each entry which contain a name and topic field. The name is what will be display as the label in the dashboard and the topic is the topic on which the dashboard will listen for updates. Updates on the topic should be in the form of yyyyy,xxxx:value were yyyyy is generally a timestamp and the dasboard will extract the value after the ':' character and display it as the value for the corresponding label
• serverPort - port on which the dashboard listens for connections
• title - title for the dashbaord paged (optional)

As a micro-app the dashboard also supports other options like authentication and tls for the dashboard connection. See the documentation for the micro-app-framework for additional details.

The following is an example of the configuration file:
