![]() Usage of websocket allow browsers and webapps such as Home 3D to be independent from proxy servers which increases the flexibility of the client servers architecture and allows clients to run on any device (Smartphone / PC : mac, win,linux). Even smaller devices with relatively low power such as ESP32 can use wifi, which solves all communication questions and can even provide a webserver hosted on the microcontroller. It is indeed promising as the current gateway reference design is based on a raspberry pi boarder routerĮthernet and wifi being used by most generic consumer devices is very convenient and is used wherever it is possible. Then comes Thread, which is the current hope of unifying all vendors and makers around one protocol and a common gateway. More and more users are crossing the step of bravery of building their own garage opener, which might be less secure as a protocol, but as it is limited to local network can occur much less risk than vendors devices that could be Hacked from the other side of the world. The same partitioning is done for the devices, where the ESP32 and the Arduino are a major player in the DIY electronics. In the diagram above, we can see a partitioning into Vendor specific Gateways and Open Gateways for which the Raspberry pi is an ideal open Hardware standard.
