Multiple Pi on Single Instance

[ashish81sharma (Ashish Sharma)]

Hi,

I am very new to IoT and developing a building automation system.

I have two buildings and have multiple floors in each building. Each floor contains multiple rooms and each room contains multiple devices at different locations.
Each location in room is connected to a Raspberry Pi.

1. Building 1
   ___-Floor 1.1
   _____*Room 1.1.1
   _______.Pi 1.1.1.1
   _________#Switch Device 1 on Pin 18
   _________#Switch Device 2 on Pin 11
   _________#Dimmer on Pin 04
   _______.Pi 1.1.1.2
   _________#Temperature Sensor on Pin 04
   _________#Switch Device 1 on Pin 18
   _____*Room 1.1.2
   _______.Pi 1.1.2.1
   _________#Switch Device 1 on Pin 18
   _________#Switch Device 2 on Pin 11
   _________#Dimmer on Pin 04
   _____*Room 1.1.3
   _______.Pi 1.1.3.1
   _________#Stepper Motor on Pin 04
   _________#Switch Device 1 on Pin 18
   ___-Floor 1.2
   _____*Room 1.2.1
   _______.Pi 1.2.1.1
   _________#Device 1 on Pin 18
   _________#Device 2 on Pin 11
   _________#Dimmer on Pin 04
   _______.Pi 1.2.1.2
   _________#Temperature Sensor on Pin 04
   _________#Device 1 on Pin 18
   _____*Room 1.2.2
   _______.Pi 1.2.2.1
   _________#Device 1 on Pin 18
   _________#Device 2 on Pin 11
   _________#Dimmer on Pin 04
2. Building 2
   ___-Floor 2.1
   _____*Room 2.1.1
   _______.Pi 2.1.1.1
   _________#Switch Device 1 on Pin 18
   _________#Switch Device 2 on Pin 11
   _________#Dimmer on Pin 04
   _______.Pi 2.1.1.2
   _________#Temperature Sensor on Pin 04
   _________#Switch Device 1 on Pin 18
   _____*Room 2.1.2
   _______.Pi 2.1.2.1
   _________#Switch Device 1 on Pin 18
   _________#Switch Device 2 on Pin 11
   _________#Dimmer on Pin 04
   _____*Room 2.1.3
   _______.Pi 2.1.3.1
   _________#Stepper Motor on Pin 04
   _________#Switch Device 1 on Pin 18
   ___-Floor 2.2
   _____*Room 2.2.1
   _______.Pi 2.2.1.1
   _________#Device 1 on Pin 18
   _________#Device 2 on Pin 11
   _________#Dimmer on Pin 04
   _______.Pi 2.2.1.2
   _________#Temperature Sensor on Pin 04
   _________#Device 1 on Pin 18
   _____*Room 2.2.2
   _______.Pi 2.2.2.1
   _________#Device 1 on Pin 18
   _________#Device 2 on Pin 11
   _________#Dimmer on Pin 04

I need to develop a control center fro where I can control all the pins of all Raspberry Pi and get status dashboard for all devices at once.
I explored and got some idea that this can be done using MQTT.
Please guide me to any tutorial where I can implement MQTT in OpenHAB2 and create a structure like above.

Is there any way I can install OpenHAB2 Server in one machine (Windows) and then connect all Raspberry Pi to them (means controlling pins of all Raspberry Pi’s)?

Thank you,

Same requirement as this recent thread, essentially

Communication via LAN to Raspberry

Hey together, i’m going to plan my new home as a smart home. So I want to read the state of all Switches and taster, Control all sockets and so on. It is not possible to get all cables to a central Point, because it is an existing house. Using knx for every item would be to expensive. So my plan till now would be, to connect every item to a central Point in its room. There would be a Raspberry Pi to Control those items. I’m at the beginning of my plan. So my question is, is it possible to comm…

Thank you!!
I have read the thread and found few example from google.

I try to implement the solution in couple of weeks and see if that works.
