About the setup
I like using Xiaomi sensors as they're cheap, reliable, and portable. This is especially relevant to my use case as I bought the majority of the sensors used in my setup as a renter. I'm in the process of building a house and these sensors will be quick to pack up and set-up in the new house. I don't trust the original Xioami gateway, which often phones home to China so I blocked internet access to the gateway, which acts as the Zigbee coordinator. Eventually, I'll remove the gateway altogether and just use Zigbee2mqtt as a bridge between each device and Home Assistant
The overview page dynamically shows entiteies based on their states. For example, only people who are home or entities that are on are displayed.
Each area tab is setup in a simliar way displaying any motion/door sensors, lighting, then media players, and finally any climate data.
