I’m trying to install the node-red-contrib-modbus package to run a modbus server on the gateway and write lora input to certain registers.
When trying to install any package though, the ‘lora in’ and ‘lora out’ nodes disappear from the palette.

I’m guessing this is the case because these nodes are not listed in the ‘package.json’ dependencies list. A factory reset puts the nodes back in.

How can I install a node red package without this happening?
Or how can I manually add the ‘lora in’ and ‘lora out’ nodes?
