Node Red is a programming tool for writing together hardware devices, APIs and online services in a flow-chart way.
I installed Node Red as a docker on my Synology 1010+.
– Open DSM, go to package Center and search for Docker
– Install Docker and open the app
-At the Registry tab, search for node-red and download the docker
-After downloading, at the image tab press the image just downloaded en select Launch.
-Add local port 1880 and container port 1880 and run the Docker image
-Now, try to connect to Node Red with a browser, using the IP of your Synology with port 1880, i.e. http://192.168.1.10:1880
