The El Gato Eve app has a field for "Siri Name" which appears for my other HomeKit devices, but doesn't appear for my indigo devices.
It seems like this is the field to change when for siri to recognize a different name for a device.
In another home bridge plugin, there was a similar issue open https://github.com/nfarina/homebridge/issues/499 and fixed in https://github.com/PatchworkBoy/homebri ... f24eefb09b.
Doing something similar for the indigo plugin adds the siri name field. Sorry, I don't feel comfortable enough with javascript to submit a pull request, but I think the fix is straightforward.
