The HobbyIoT NET is an MQTT-SN protocol implementation over 802.15.4 wireless connection. It links together number of end devices (MQTT-SN Clients) capable to measure and control various parameters and appliances. Each End device connects to the MQTT-SN Gateway and exchange information over it with the MQTT Server. This server can either just pass the information or - if programmed - make decisions how to manage the sensor network by itself.

The HobbyIoT DEN in an Node MCU ESP8266 based system for terraruim remote control and monitoring. The communication protocol is pure MQTT over the WiFi connectivity. The current implementation allows 2 temperature sensors and two relays to be managed via OpenHAB interface. Rules are implemented within the OpenHAB server so automatic lights ON and OFF could be arranged at desired times.

The HobbyIoT DOG system implements a remote monitoring system for a house. The system is based on RaspberryPi, 3G modem, web cameras, OpenHAB server and uses MQTT secure connection over the mobile network. It also support reverse SSH tunneling for remote access and administration. Currently three web cameras are connected and making pictures periodically together with sending keep alive messages and CPU temperature.

A funny project to remotely run the DigiBird to sing songs. DigiBird is an electronic creature capable to sing songs alone or in chord. We are trying to talk to it on its language using combinations of tones according DigiBirds decoded - to ask bird to sing a song. The project uses NodeMCU ESP8266 together with I2S DAC, amplifier and a speaker. And of course - a DigiBird :)
