@mcm1957 I mean the modbus adapter, the main point that I want to be able to do this for is so that I can update all of the instances at once if I need to make changes instead of having to manually go through each of the instances.

I would like to be able to automatically generate an instance (or at most with 1 or 2 clicks) when I connect a new TCP device with a predetermined and known IP adress. Does anybody have any tips for this? I tried using the JavaScript adapter but I couldn't find any node modules which had this functionality. Thanks in advance.

is that what you mean?

@fastfoot I ran the command again using the directory you said and Im still getting the same errors, I can even see in the node_modules directory that I do have Modbus-serial installed

@fastfoot I use windows

@fastfoot Thats the thing, I do not have an /opt/iobroker directory, it does not exist is what the terminal tells me

@fastfoot I tried this code which I copied and edited from the modbus serial documentation and I am getting these errors

@homoran Im still getting this error even after adding modbus-serial to the instance, are there perhaps other steps I can take to troubleshoot this?

@homoran I did add it to the npm modules in the javascript instance but there is still the error, I think maybe its because I didnt download it to the correct directory , where do I need to download it to?

@homoran i did so by typing 'npm install modbus-serial' into the terminal in iobroker, im not sure what you mean by add the npm package via its instance.
