Running other homebridge instances

Hi,

I'm sure I've seen discussion previously of running other homebridges in conjunction with homebridge-indigo / HomeKit bridge, but I can't see how to make it work. What I want to do is run the homebridge-landroid plug-in to link to my landroid automatic mower. https://www.npmjs.com/package/homebridge-landroid

The installation instructions are very basic:

Install homebridge using: npm install -g homebridge
Install this plugin using: npm install -g homebridge-landroid
Set up homebridges config.json with your Worx account data

Question: if I follow these instructions, am I likely to mess up my current homebridge-indigo installation? Is there anything else I should bear in mind?

Sorry for rather vague question.
