Please take a look at the following topic: How to connect Philips Hue lights to a Philips Hue bridge?
You can try to connect the lights by serial number or touchlink method.
Also please make sure to select your Philips Hue bridge and do not select the option Philips Hue Bluetooth.
If that does not work for you, please get in touch with Philips Hue. This community is about the Hue Essentials app.
