Automations  
  
    Symfonisk volume rotary remote  
  
 The gola of this Automation is to adjust the volume of the sonos system with the rotation but also use the press to play pause another system wich is a smart Samsung Tv.

- HA entity input_text : https://www.home-assistant.io/integrations/input_text/
alternative to HA Integration : Without HA, it is necessary to pair the rotary remote with IKEA gateway, although it is enough to control the volume, it does not allow fine adjutment and combining functions with different devices.
   Bluetooth  
  
    BLE Bluetooth Low Energy  
  
 - This is a simple integration that tracks BLE devices and beacons without even requiring pairing (privacy notice might be required)
   Bluetooth Mesh  
  
 - One investigation path for integrating Bluetooth mesh in Home Assistant is bridging it through an ip layer using theBearer Layerof the BLE Architecture
BLE Mesh => IP => MQTT-SN => MQTT => Home Assistant   MQTT  
  
 - MQTT : Message Queuing Telemetry Transport, is a first class citizen in Home Assistant
   Zigbee  
  
 - Zigbee : Low power mesh network, allows to extend the network with repeater devices e.g. zigbee light bulbs. This Home Assistant inetgration is based on Zigpy
   Thread  
  
    CHIP - Connected Home Over IP  
  
 - I'm still analyzing the options how CHIP can or will be integrated in Home Assistant
   MQTT-SN over Thread  
  
 - MQTT-SN integration should be trensparent to Home Assistant and treated as any other MQTT connection
- MQTT-SN is a light weight protocol that plays the role of a bridge between an MQTT broker and constrained devices that need to minimise payload and packets traffic. Therefore it's appropriate for Low power wirelss mesh netwroks such as Thread
