Ethernet Gateway Hub

[rush]

Hello everyone,
recently I've deployed MySensors Ethernet Gateway on an iTead's iBoard W5100 and got bit by the Arduino / MySensors limition - single connection to the gateway.

As I'm experimenting with Node-RED, Domoticz and might be adding HomeAssistant to the mix, I tried really hard to find a working solution to this situation and failed.

Arduino and MySensors could be fixed to support up to 4 connections but in the end I decided to solve the problem by a simple Python script that relays gateway messages to all the clients and messages from a client are relayed to the gateway.

I thought someone else could be in the same situation so here you go: https://gist.github.com/radek-senfeld/5086fbc40cc86c06478be85c533a718a
