I recently embarked on a project to integrate my Z-Wave devices with group control functionality, and I’m thrilled to share my success story! 
After some research, I discovered that while group control is typically associated with Wi-Fi lights, it’s indeed possible to use it with Bluetooth RGBIC LED lights as well. I have four different sets of strips, and setting up group control has transformed how I manage my lighting setup. It’s incredibly convenient to control all of them with a single command! 
However, I did run into a minor hiccup when trying to configure the subnet mask on my Hassio running on VirtualBox. I accidentally changed it to /32, which cut off access to Home Assistant. Thankfully, I found a solution without needing to dive into HA, which was a huge relief! 
If anyone has tips on optimizing group control for Bluetooth devices or has experienced similar subnet mask issues, I’d love to hear your insights! Let’s keep the conversation going and help each other troubleshoot and improve our smart home setups.
