Hy there!
I’m a beginner in Openhab, but i want to try to accessing my existing hardware with it. My system is simple, i have a 3 level house, and i want to control lights, heating, alarm, accessing the house, and later the multimedia and garden irigation.
The main core will be a RPI and an arduino mega, and a lots of relays and maybe dimmers (designed by me). Ewerything in the whole house is cabled, so no need the wireless transmission.
Summary of the needs:
- Lights.
I have over a 30 different light circuit, and for each i have push-button mounted on wall. For each push-button group i have cat5e cable, with 2x4 wire twisted, max. 3x2 used for switching the light, and 1 pair for i2c connection of temp and humidity sensor.
Can anybody tell me if i can handle all the gpios available on the rpi and arduino mega? Is it possible tho control 2 arduino board with rpi? Or there is an orher smartest sollution to have more gpios?

The heating.
I have an ordinary gas boiler (Viessmann Vitopend 100). I need 3 zone for heating correspomding to the 3 levels in my house, working absolutelly independent, but using the same boiler. I want to collect data from the wall mounted sensors and compared somehow with an thermostat program, that command the boiler and the 3 main valve. -
Alarm.
I have a DSC alarm system, with cables PIR sensors, i have 2 zones. I want to control ower app or browser this. Also i want to collect datas from the PIRs to make rules and scenarios for lights. -
Intercom, entrance system.
I wanna have an lcd beside the entrance door to controle the whole house with video intercom. -
Multimedia.
It resume only in multi room sound.
I have 5 different room, and i want to stream the music from my mobile device over wifi, and to have different music in each room, or the same in a few rooms etc.
