I’ve been diving into the world of smart home automation, and I must say, it’s a fascinating journey! 
Over the past few weeks, I’ve been experimenting with different gateways and integrations to streamline my setup. One of the most intriguing options I’ve come across is Zigbee2MQTT. The idea of decoupling my Zigbee network from Home Assistant is incredibly appealing, as it offers a lot of flexibility and control. However, I stumbled upon a challenge that many seem to face: when discovery is turned off, devices aren’t automatically added to HA, and grouping them becomes a bit of a puzzle. 
After some research and trial and error, I found a solution that works beautifully for me. By specifying all devices in my network through a configuration file, I can ensure that each device and its entities are exposed via the Zigbee2MQTT gateway. The key was figuring out how to group related entities under the same device in the UI without relying on MQTT discovery mode. It turns out, with a bit of YAML magic, it’s entirely possible! 
For example, my Aqara temperature sensor now neatly groups temperature, humidity, and battery level under a single device card in HA. This not only makes the interface cleaner but also enhances usability. If anyone is struggling with similar issues, I’d be happy to share my configuration setup or troubleshoot together. Let’s keep the conversation flowing and help each other optimize our smart home setups!
