Wait, now I'm confused after reading through earlier parts of this thread.
OmniLinkBridge and Mosquitto are working, which I know because I see constantly updated messages from the Omni in MQTT Explorer. HA is working, which I know because I can control Insteon lights through the interface, since I installed the Universal Devices ISY994 integration.
Nothing from the Omni is showing up yet in the HA interface I was assuming that's because I need to install the Mosquitto add-on. Is that correct? What about the MQTT integration? Is that needed? And I read about an OmniLinkBridge add-on. I can't find such a thing. The Add-on store has a ton of stuff in it, but not that.
Everything is running on one Win7 box, including HA, which was installed as a VirtualBox VM.
