Is RedPLC package included in Unipi's Node-RED OS image?
this package is not included in our images, only our is: https://flows.nodered.org/node/@unipitechnology/node-red-contrib-unipi-evok
The packages can be added later of course. Using another OS image (such as Raspberry Pi OS) can be harder to configure - you need to install Evok. The Ubuntu Core OS is not supported and probably won't work because of the different package names and versions.
