+Example Hue Light:
+```
+[HueLight]
+    - implementes [LightDevice]
+    - uses [HueBridge]
+```

+Example with ZigBee2Mqtt Temperature and Matrix Clock Temperature:
+```
+[Z2mClimate]
+    - implements [ClimateDevice]
+    - uses [Z2mBridge]
+    
+[MatrixClock]
+    - implements [ClimateDevice]
+    - uses no bridge, works on a per-device connection
