Are you still on the same network as the hubs for each of these brands?
LEXI Hub needs network connection from which it can control the added Philips hue lights.
When you configure your Philips devices on LEXI platform, please ensure that your LEXI Hub is also connected to the same network on which the Philips Hub is connected.
If you switch the network of your LEXI Hub to another network, Philips Hue devices will not work as the Philips hub is configured on a different network.
Feel free to contact us if you need any further assistance.
Note: You cannot control the Philips Hue lights connected to your LEXI Hub if you are operating your LEXI Hub on Portable mode.
