I'm researching how different devices in a smart home integrate through protocols like Zigbee, Z-Wave, or Matter. I'd like to better understand the application layer and how security is managed between sensors, actuators, and the cloud. Additionally, what challenges exist when scaling a home network and maintaining interoperability between devices from different manufacturers? Has anyone delved deep into the architecture of these systems or has recommended resources to continue learning? I'd appreciate your experiences and suggestions to advance in this topic.
How do communication protocols work in a Smart Home, and what challenges do they present?

In my first apartment, I installed Zigbee bulbs and a Z-Wave motion sensor; when I tried to control them from the same app, I noticed the hub had to translate between protocols, which caused some delays and required regular firmware updates. From that experience, I learned that to scale smoothly, it’s key to choose devices that support Matter, as interoperability and security are handled more uniformly that way.
