The domy technology is based on devices that interact with each other and/by coordinator via radio using panStamp NRG2 (TI CC430 microcontroller SOC, which includes a MSP430 MCU core and CC1101 868MHz radio). Each device contains a panStamp and Network hub comes with the  coordinator device that communicates with the embedded computer with OS GNU / Linux Debian.

domy  Network hub communicates with devices using protocol SWAP (Simple Wireless Abstract Protocol), that allows event-driven communications. The device is not continuously interrogated (polled) by the coordinator about change of state in the shortest possible time, but it is the same device that broadcasts immediately after a change of status in the exact moment it occurs (event-driven). Note that the difference between "shortest possible time" and "exact moment" can reach, in some cases, about ten seconds.

The network that connects the devices is so substantially free and helpful and the same devices alert if there are changes. This mechanism allows you to apply to our devices more commands coming from outside the network (the relay button, the remote control, etc.) counting on maximum possible interaction and without resting on communication and CPU. The system used by domy then allows immediate responses to events that can be exploited to improve much more the interactivity with your own home. Moreover a keep-alive transmissions cycle is conducted at regular intervals to ensure that the devices are connected and operational.

The concentrator has, as standard equipement, a panStamp network coordinator, which allows trasmissions with all domy devices through SWAP protocol. It is possible to add gateway to 4noks networks (ZigBee), Homematic, ZigBee or Z-Wave.

Software used: GNU / Linux Debian - MQTT mosquitto / PAHO - HTML5 - JavaScript - apache2 - php - sqlite - pyswap.swapdmt.lagarto-swap .... completely free software.

With a nice graphical interface, the user can manage the entire system intuitively with few clicks. Indications and suggestions are shown at necessary points.

The interface allows you to integrate new devices, manage Telegram bot, view individual devices, associating them as you prefer (eg. rooms, type of sensors ...), manage monitored data and produce graphics database, create scenarios based on actions derived from three causes (scheduling, device status and Telegram messages) that give commands to devices and send Telegram messages. Causes and effects may contain combinations, free  in number and type. Transmission of the devices is event-driven with keep-alive time.

For safety, the GUI is displayed only within the LAN area, while if yuo are outside domy  Network hub is reachable only by Telegram messages and by bots associated with the Network hub that the user can create or change as he wishes. You can authorized  specific users and they are recognized and associated  sending a specific message within 30 seconds since activation.

The software is already installed on a micro-SD card to 16GB, which allows operation of the system up to 5 years. Removing the card, you can make a back-up any time you wish on a normal PC. Software updates will be made available by Homatron for new devices or to improve performance. You will evaluate if to install them or not.
