Raspberry Pi collects data from various sensors and devices, for example temperature, heating status, weather, the state of watering your plants, security status, rain sensors, windows and entrance status, timers or alarm clocks, alerts on breaking news etc. By Raspberry WEB page you can set up priorities of the connected sensors and their respective alert messages. You can switch LEDs on/off, use buzzer sounds etc.
All devices are interconnected by your home WiFi network.
Displays consist of small OLED display, three different colours LEDs and a buzzer. A module ESP8266 is included as well.
Raspberry Pi collects information and monitors events at your home and compares them to your pre-set limits and priorities. Subsequently the device sends an information to multiple parallel displays. The particular event can switch a LED or a buzzer on. If there are no incidents at your home, the wheather or a time information can be displayed (according to your preferences).
I decide to use two separate wifi networks. One for home devices and other for displays and sensors. For me it is much easy to use wifi network for sensors because ESP devices and a lua scripts possible usage. Thru the network I can switch on and off for example light or horn too.
Raspberry as a server for the system is used. It is open for any devices to connect. WIFI, wired or web based.
There are digital inputs and relay to control something wired.
