29/1/2019 Are you a fan of open-source software solutions? We have great news for you - all UniPi controllers are now fully compatible with the Node-RED!
What is Node-RED?
Node-RED is a user-friendly open-source programming tool, which uses so-called “flow-based” method. This approach describes the application's behaviour through a series of nodes with each node having its own pre-programmed function. According to this function, the node then processes incoming data and sends them to the next node in line. This creates a flow of data between nodes.
This approach represents a very intuitive and user-friendly way to develop applications by simply placing the right set of nodes without the need to write custom code. In the case of Node-RED, the programming interface is then easily accessible through a web browser. All you need to do is to interconnect each node and set up their functions - after that, you can control inputs and outputs of your controller as needed. Due to the open-source nature of the project, users then can share their flows with the Node-RED community and easily import or export them to their projects in JSON file format.
Node-RED on UniPi controllers
In cooperation with JoTio Tech s.r.o. a pair of Node-RED nodes was created to allow the use of Node-RED on UniPi controllers. A single input and a single output node utilize the EVOK open-source application programming interface (API) for communication with the controller and acts as a link between Node-RED and UniPi hardware.
An example of local Node-RED install on an UniPi controller
Visit the UniPi Knowledge Base for step-by-step Node-RED installation guide both for UniPi 1.1/UniPi Neuron and UniPi Axon controllers. A Node-RED section was also created on the UniPi technical forum for the case of any technical questions or issues.
Special 15% discount!
To make your start with Node-RED easier, we prepared a special discount. From 29th January to 5th February 2019, you can enjoy a 15% discount to UniPi Neuron S103 and UniPi Axon S105 controllers!
Both these models represent the most compact and most versatile models of their respective model lines. Both S103 and S105 feature 10 I/Os, broad connectivity and compact size of only 4 DIN modules, giving them an excellent size-to-I/O number ratio.
Note: The discount cannot be combined with any other discount or special.
