Hello fellow smart home enthusiasts! I’ve been diving into the world of ZigBee smart lighting automation with OpenHAB, and I wanted to share my experiences and some questions I have along the way. ### My SetupI’ve recently added a few IKEA Tradfri bulbs and switches to my setup, aiming to create a seamless lighting automation system. The goal is to have the lights automatically adjust based on time, motion, and even manual overrides through voice commands. ### The Journey So Far1. Device Pairing: Pairing the Tradfri devices was a breeze using the ZigBee binding in OpenHAB. The bulbs and switches showed up immediately in the inbox, and configuring them was straightforward. 2. Rule Creation: I’ve set up some basic rules to turn the lights on at sunset and off at bedtime. However, I’ve noticed an issue where the brightness doesn’t adjust smoothly—it either goes to full brightness or off. 3. Motion Sensors Integration: I’ve integrated motion sensors to trigger the lights when someone enters the room. This works well, but I’d love to add a fade-in effect for a softer transition. ### Challenges and Questions1. Brightness Adjustment: Why does the brightness jump to 100% when turning on? Is there a way to set a default brightness level? 2. Scene Creation: I’d like to create different lighting scenes (e.g., reading mode, movie mode) but am not sure how to combine multiple devices into a single scene. 3. Voice Control: While I can control individual lights via Alexa, I’d love to group them for easier voice commands. Any tips on how to achieve this? ### Seeking AdviceIf anyone has experience with similar setups or can shed light on these issues, I’d greatly appreciate your insights! I’m also curious if others have tips on optimizing ZigBee performance or recommendations for additional devices to enhance the system. Let’s keep the conversation going and help each other create smarter homes!
