MQTT Borker on ESP8266

Running an MQTT broker to serve all devices for a house (20pcs) requires at least a Raspberry Pi or equivalent. But the SD card fails from time to time and requires some Linux skills to make it work; the final price for which is over USD 70.

But how about running an MQTT broker on an USD 3 ESP8266 chip? Is it possible? Yes, it is! Go to http://iotcentral.eu and with few clicks you will be able to flash your ESP8266 (4Mb) with the binary. No need to compile code or to solve errors, just click and run. More than that your MQTT broker will communicate with your iotcentral.eu instance, so you still get your messages on your phone if your mobile app is connecting to the websockets to your iotcentral.eu cloud instance.

But what if I am at home and my internet connection is down? Can I communicate with my devices or am I isolated? Don't worry, your mobile app will still be able to connect to the ESP8266 MQTT Broker over the websocket, so you can control your devices.
