When the node-red starts, the flow(program) picks up the pre-programmed serial port, open it, and starts the communication. But there are some cases the port needs to switch to a different port, stop, and start again. For example, in order to upload a new binary for Arduino, the ser...
If each of your nodes are meant to haveexactlythe same configuration, then you can scale up the deployment as usual. However, in many cases each node is meant to run different code. It may even have different hardware attached, as in the example above. The first trick is to use the no...
A first view example It works by allowing you to wire up web services or custom “nodes” to each other, or to things, to do things like: Send an email on a rainy weather forecast. Push sensor data to services like Twitter. Perform complex analysis on data with ease. Installation Instal...
As soon as you get past the first blinking example, you can start preparing the IoT portion. 4.Build Control Flow. Here is the simple flow setup. 5.Configure Email Node Now we can configure the email node. I am using the Microsoft office email server. If you are using another email se...

Docker-Compose linking example Another way to link containers is by using docker-compose. The following docker-compose.yml file creates a Node-RED instance, and a local MQTT broker instance. In the Node-RED flow the broker can be addressed simply as mybroker at its default port 1883. version...

Note that once configured in SignalK, for example a USB-serial port, that port is no longer normally available in Venus OS. For example, when plugging in a USB-GPS; and then adding a connection for its corresponding tty in the SignalK, makes for that GPS to be no longer be recognised...
