Ready to use KIT for home automation system that includes Rock PI S single-board computer ARM 64bit, metal enclosure, high-endurance 32GB memory card within Debian Linux, Domoticz, firewall and backup system.
It also includes 1 Modbus power and energy meter, to measure power, energy, voltage, frequency and power factor, 1 USB/RS485 adapter to connect DomBus modules to the Rock PI S, 2 power supply unit and 1 DomBus34 domotic module: it manages up to 4 energy meters, have 2 relay outputs to enable/disable appliances, 1 AC input to monitor 230V presence, and 2 low voltage inputs that can be connected to pushbuttons, switches, gas and water meters, ...
This is a start kit, plug and play, that permits to build a domotic system easily and start monitoring the building consumption with nice charts and compare function in a week by week, month by month and year by year basis.
When connected to the power supply and LAN, it's possible to connect to its IP address (automatically assigned by the DHCP service) through:
Rock PI S is a smaller and cheaper alternative for the (often not available) Raspberry PI 4 single board computer, with less RAM but with a compact form factor and very low power consumption, ideal solution for optimized software like Domoticz (written in C++).
It should be supplied by:
The microSD already includes Domoticz home automation system: this is a free open source software written in C++, that works perfectly even in this small hardware.
Domoticz permits to manage serveral different type of hardwards, like ZigBee, ZWave, and many other wireless and wired protocols. Also, Creasol DomBus protocol is supported, so it's possible to connect through a RS485-USB adapter, many modules (for analog/digital inputs, analog/digital outputs, relay outputs, sensors, LEDs, lights management, EVSE to manage electric vehicle charging, ...).
Using Domoticz and DomBus modules it's possible to:
Many hardware plugins can be installed and updated automatically. Also, many scripting languages are available to create simple and complex automations, like Lua and Python. Very simple automations can be created using a graphical language, named Blocky.
RK3308 have two IO voltages, 1.8V/3.3V. For ROCK Pi S, the voltage level of GPIOs showed in the tables above are 3.3V and tolerance of those are 3.63V.
Rockchip RK3308 GPIO has 5 banks, GPIO0 to GPIO4, each bank has 32pins, naming as below:
GPIO0_A0 ~ A7 GPIO0_B0 ~ B7 GPIO0_C0 ~ C7 GPIO0_D0 ~ D7 GPIO1_A0 ~ A7 .... GPIO1_D0 ~ D7
For Rockchip 4.4 kernel, the GPIO number can be calculated as below, take GPIO4_D3(PIN8 on 26PIN GPIO) as an example:
GPIO4_D3 = 32*4 + 8*3 + 3 = 155
To set GPIO4_D3 output
cd /sys/class/gpio echo 155 > export cd gpio155 echo out > direction echo 1 > value # output high echo 0 > value # output low
