Welcome!
You have two options to control original hue products.
Import your Lamps from original bridge Into diyhue and use your genuine bridge as a transceiver. Sensors and switches can’t be imported.
Use a conbee hardware dongle (~35€) by Dresden Elektronik. It is a zigbee transceiver that enables you to talk directly to zigbee devices like the original products including Ikea devices and sensors & switches.
Background info: while Diy lights with esp8266 controller connect via wifi to your network, genuine bulbs and sensors use the zigbee wireless technology that needs a special transceiver.
