Yes I know its ancient, but the set up been working well with broadlink node for my home automation for ages, so never bother to upgrade. (I do have another Pi with more up to date nr for tinkering)
I dusted off the Pi3b the other day and was playing with some servo connected with the node-red-node-arduino. I thought I will update the arduino node via the palette, and now I get "Flows stopped due to missing node types -arduino board." on the palette it has a warning " * Missing serialport dependency"
how do fix this dependcy for the node-red-node-arduino
If not possible how do I revert to the old version that works.
how do I get the other flows to start, so my HA works, as all flows have stopped (edit I solved this by deleting the node in the configuration node)
