This plugin crashes Homebridge

[zork17]

I get the following:

Mar  7 12:41:15 RSBPI homebridge[7841]: throw new Error("The requested platform '" + name + "' was not registered by any plugin.");

I have installed the plugin. I have two Homebridge services - one that handles the KNX devices and one with all the rest. Maybe I need to install the plugin in a different way than other plugins? Does this plugin support multiple Harmony hubs?

[materik]

It should. Are you sure you have setup your config.json file correctly?

[zork17]

in the config.json I've just added:

{
        "platform": "HarmonyHub",
        "name": "homebridge-harmonyhub-plugin"
}

I installed it like every other plugin: sudo npm install -g homebridge-harmonyhub-plugin

[materik]

should work :/

[zork17]

but it doesn't. anything I can do?

[materik]

your setup seem fine by me. so the only thing that I'm not sure about is the two homebridges so should be related to that.

[zork17]

As I said I have 2 Homebridge services: Homebridge which has all the KNX devices. and Homebridge-NKNX which has all the non KNX devices, including this plugin in its config.json.

The service definition file for both of them is the same, except for the command line parameters for Homebridge.

The command line parameters are:

HOMEBRIDGE_OPTS=-U /var/homebridge
HOMEBRIDGE_OPTS_NKNX=-U /var/homebridge-nknx -P /home/pi/node_modules

I saw this setup somewhere in the Homebridge or KNX forum. They worked for me until now for all plugins.

This is the documentation for the parameters:

-P, --plugin-path [path]        look for plugins installed at [path] as well as the default locations ([path] can also point to a single plugin)
-U, --user-storage-path [path]  look for homebridge user files at [path] instead of the default location (~/.homebridge)

I installed the plugin like this sudo npm install -g homebridge-harmonyhub-plugin from /home/pi

Is there anything I can do to make this plugin work?

[materik]

could it be something to do with you running it as sudo.

[johanhansen]

Are you sure that the plugin actually is located in /home/pi/node_modules? My experience is that the node_modules can end up in unexpected locations. Try to omit "-P /home/pi/node_modules" and let Node find the plugin by checking it's known node_modules locations.

I tried to install without sudo but it doesn't work

I also tried without -P /home/pi/node_modules but homebridge crashed because it didn't find other plugins.

Since this configuration worked for me with many plugins, I think there must be a differece in the install of this plugin that causes it to crash in my setup. I noticed that during the install there was some kind of compilation...

[materik]

can you see if the package is located in the folder home/pi/node_modules/

[zork17]

no, it is not in: home/pi/node_modules/ it is in: /usr/lib/node_modules/ with many other plugins that work fine.

[materik]

try to install it at both locations...

[zork17]

how do I do that?

Also, I think my problems are because I have 2 places with modules: /usr/local/lib/node_modules and /usr/lib/node_modules is there a way to tell the system to work from now on with /usr/local/lib/node_modules since when I install a new platform it is installed there, but it is run from /usr/lib/node_modules

[materik]

either you can copy paste the folder to this location or do a symbol link or can't you supply install location to npm install?

[zork17]

It now finally works after removing all plugins and installing again in the same place.
