Ring: more than one homebridge instance not starting

[divemasterjm]

hi i have 4 homebridge instances, therefore same plugins are shared but in the plugins where there is not ringalarm platform in the config they cant start due to the following error on start up
Load homebridge-ring-alarm.RingAlarm

is like you need the platform entry on the config even if you dont use it in this instance

That's really odd. Looks like homebridge will call the platformConstructor with null config if it finds the plugin but it isn't configured (https://github.com/nfarina/homebridge/blob/84b4733ac75aba9e7c19d36be282cd8162077860/lib/server.js#L358). Had no idea it could do that. I'll add a check to make sure there is a config and just return out if there isn't.

That seems like an odd setup. Just curious, what lead you to need 4 homebridge instances?

hi, others plugins works flawesly, i have 4 instances for various reasons, more than 100 accesories and specially cameras, if they have a problem homebridge becomes in "not responding state".

meantime like workaround i wrote in all other configs a platform with bad user/pw, ive got and error but starts, waiting for your solution and thanks for all

@divemasterjm give v3.2.1 a try. Should just see a log that says there is no config, with no error taking down the homebridge instance.

give v3.2.1 a try

[divemasterjm]
