Raspberry Pi - SmartHome IoT Pi System  

         Raspberry Pi - SmartHome IoT Pi System

                  for Raspberry Pi B+ & B2


     The SmartHome IoT Pi has unlimited functions,

           the only limit is your imagination!


For beginners you can start with IoT Pi-R1 , use the on board relay control for the ON/OFF through the Internet ( you must have Internet with your Pi Wifi or Ethernet), All of our boards for the IoT Pi system have a model number & serial number that will need to match with our IoT Cloud database, our IoT Pi software runs in Pi furthermore it will detect the system and detect which type module board plug-in, and enable the function to collect the data & update to IoT Cloud.






The SmartHome IoT Pi project is aimed towards creating a system capable of controlling devices over the internet from any device.
Currently the system supports up to 12 Controlled devices and 1 DHT 2302/22 Temperature and Humidity Sensor. The main device ( G1 ) Can be triggered by
temperature (with a DHT sensor) or time. The system uses Solid State Relays ( SSR ) or Switching Relays, The Switching Relays are louder and sound a "Click" when they switch.

   The Switching Relays also cannot support up to 20Amps or 40Amps like the SSR's can do. The system can be deployed to control your air conditioning during
the hot summers or electronic heaters during the winter, another use would be to wire the system up to your house lights / power and control your lights
from over the internet.

    Additional items are the
Yellow/Blue 0.96 128x64 OLED LCD
screen to show extra info, last command sent and a countdown to update / check server status and also show Temperature and Humidity.
The advantage to using our system over another system is that everything is built for each other ( The Temperature sensors, the relays, and the screen ).
The system uses the internet through WiFi or an Ethernet cable to connect to our secure servers which enable the website interface and the Smartphone to easily communicate with your device.
