Self-signed SSL certificate for the INSTAR MQTT Broker and Node-RED

Q: How do I use a custom SSL certificate for the INSTAR MQTT Broker with Node-RED?

A: We already showed how to set up your INSTAR MQTT Broker with a self-signed SSL cert. Following this guide we now have one camera configured as our MQTT Broker and a second cameras configured to be a MQTT Client on our MQTT network. Both cameras communicate SSL encrypted using a self-signed certificate.

Make your camera the heart of your smart home

INSTAR MQTT

Using the MQTT interface of your INSTAR Full HD cameras you can connect them to an existing smarthome system (Home Assistant, OpenHAB, Node-RED, Athom Homey, Homematic, ioBroker, Loxone, homee) can be added. Or even make it the main broker for your MQTT sensors. MQTT allows you to automate ALL functions of your camera and link them to other services in your smarthome.

Control your camera via the IFTTT online service

INSTAR IFTTT

On the IFTTT platform, we provided a service called INSTAR. The INSTAR applets provide you with the ability to control some settings of your INSTAR camera or INSTAR Cloud with IFTTT. You can connect INSTAR with triggers for location (Geo Location) and date & time, send notifications and much more. For example, you can connect INSTAR applets to the IFTTT location service and automatically disable the alarm when you arrive home. You can also use the INSTAR applets to create your own automation and connect them to other third-party applets.

Camera Setup

The broker camera is using the broker.pem file as SSL certificate:

Node-RED Self-Signed Cert for INSTAR MQTT

And is configured to use it's own MQTT broker (127.0.0.1) with a user login:

Node-RED Self-Signed Cert for INSTAR MQTT

Node-RED Setup

We can now continue by adding the broker to Node-RED:

Node-RED Self-Signed Cert for INSTAR MQTT

Add your broker cameras IP address and MQTT (TLS) port (default: 8883) and click to edit the TLS configuration.

Node-RED Self-Signed Cert for INSTAR MQTT

Now upload the client.pem file as the certificate for the broker connection.

On the security tab you can add your broker user login.

Node-RED Flow

We can now continue to add a few MQTT Nodes to control both of our cameras. Add a few MQTT topics with the MQTT ID of your cameras:

Node-RED Self-Signed Cert for INSTAR MQTT

This flow allows me to either, selectively activate or deactivate the 4 motion detection areas on each camera. Or switching all of them on or off using the "all" Topic:

You can now switch to the Node-RED UI and give it a try:

Node-RED JSON Flow Export

You can import this flow to your Node-RED dashboard. All you need to do to make it work is adding your personal MQTT Broker to all MQTT nodes and changing the MQTT ID that are used to address each camera:
