I recently faced a challenge similar to yours when trying to control multiple Hue dimmers in my hallway using a single slider. Initially, I was frustrated because each dimmer could be controlled individually, but grouping them proved tricky. Here’s how I resolved it and the satisfaction I felt once it worked seamlessly.First, I realized that grouping was the key. I created a group named ‘Hallway Dimmers’ and added all the individual dimmers to it. In my items file, I defined the group and included each dimmer. This way, any change to the group would affect all the dimmers within it.In my sitemap, I set up a slider linked to the group. This allowed me to adjust the brightness of all dimmers simultaneously with a single gesture. It was a relief to see everything work as intended after some trial and error.I also discovered the importance of ensuring all dimmers were correctly configured and that their Hue settings were compatible. This attention to detail made the system more reliable.This setup has transformed my hallway lighting, making it easier to adjust the ambiance with just a swipe. It’s moments like these that remind me why I love tinkering with smart home technology—it’s all about creating a more convenient and enjoyable living space.If anyone else is struggling with similar issues, I recommend double-checking your group configurations and ensuring all devices are properly integrated. The community here is fantastic, and I’m grateful for the support and resources available. Happy smart home hacking!
