I changed my WiFi AP (old Apple to Google), including SSID. I rebound Milight WiFi device to the new SSID. Milight bulbs work from the native app, but stopped working from OH. I rechecked Milight config, IP for Milight WiFi still the same. I tried to change Milight channels, thinking that the order of those might have changed after resetting Milight WiFi. None of 4 works.
If you are using Milight I would setup one of these opensource hubs and use this binding. I have only ever used the opensource hub to control mine so cant help with your questions.
