I'm not sure if you can connect six detectors together directly. SmartLife sensors don't seem to be designed to work as an interconnected network, where one sensor automatically triggers the others. However, you can connect them individually to your Wi-Fi network and use the SmartLife app to create automations with other compatible products, such as turning on lights in the event of an alarm. For more details on multiple connectivity, I recommend you consult the product manual or contact Nedis technical support.
