Error installing node-red-contrib-modbus

Hey Team

We're trying to do Fronius inverter control with Node-RED. It works fine as long as we're on grid with the Victron pallete but when we're on generator and trying to control the Fronius, it seems to ignore attempts to disable PV inverter (VE.Bus control) or set inverter power to 0W (PV Inverter control).


We thought we would try Modbus TCP commands but the pallete does not install.


I'm not clear on how much we can and can't ask from Victron about Node-RED, so I err on the side of asking :P

It looks like an issue with their package, I can't install it either and it seems to fail when the package manager fails to find a file in the repository.

@Warwick Bruce Chapman @nickdb

node-red-contrib-modbus installs fine here on venus-os 3.00~4

tested first in terminal with

npm install -g node-red-contrib-modbus (no error)

Then from node-red web intreface (no error)
