Home Automation with Openhab

I have recently started a new project in the area of Home Automation. My goal is to use as much opensource as possible and ofcourse do not pay more for brand names (like Philips) when it comes to buying smart products.

My setup:
 - Hardware: Raspberry Pi 3 (You can choose Pi 4)
 - OS: Raspbian (Raspberry pi OS Lite version). Download here
 - Automation Tool: Openhab
 - Motion and Light Sensors: Motion and Light sensor. 
 - Smart Lights: IKEA
 - Wireless protocol: Zigbee
 - Zigbee Broker: CC2531
 - MQTT Broker: Mosquitto
 
Why I chose what?
 - Raspberry  Pi3: Because it was the only low powered computer available at my home which I can run 24/7. If you are buying new one, go for Pi4. If you already have a PC/Laptop at home which runs 24/7 then you should use that one.
 - OS: The reason I am using Raspbian is that I want to run other applications on Raspberry along with openhab so I didn't want to use Openhabian. If your Pi will be used only for openhab then go with Openhabian.

Cut through vs Store and forward switching

Image
Switching infrastructure has evolved since 4 decades from hub, bridges ASIC based switches, FPGAs based switches etc. Switches operate at layer 2 (Data link Layer) and their purpose is to receive a frame on one port (Ingress port) and forward it to another (Egress port). This decision is based on Destination MAC (DMAC) address. Here we will describe how store and forward switching works and how cut-through switching works. Store and forward switching Following figure shows Layer 2 frame. Bytes are received from left to right. Our main focus would be on Frame header and Checksum field. Checksum field in Layer 2 frame is used to check integrity of the frame (Error control). Integrity means performing some checks to find out whether frame was tempered/corrupted in between or not. Checksum is certain type of hash calculation over whole frame data. This means we need to have all the bytes of frame before checking for integrity.  As soon as we have whole frame and checksum c

SSH Tunneling or SSH Port forwarding

Image
One of the tricky topic is SSH port forwarding. There are many tutorials about this but they are quite complicated for students or junior level engineers to understand. Here I will try to explain those concepts using scenario so that it can be easily grasped.  Scenario: Your office firewall blocks access to facebook.com URL. Your laptop at home can access facebook.com easily. Your office environment/firewall allows SSH connection to your home laptop. Goal: Make office PC access facebook.com without performing any changes to office firewall. Description: In order to achieve this your home laptop needs to run SSH server. What we need to do in this case is to create a SSH tunnel from Office PC to Home Laptop and do some port forwarding.  In above figure you can see that if we can create tunnel between office and home machines. Just a SSH tunnel won’t allow us to access facebook.com from office PC. We need port forwarding here. In order to achie

Virtual port channel (vPC) or Multichassis Etherchannel

Image
Virtual Port Channel A port channel combines multiple physical link into a single logical link provided that these all physical links must belong to same network switch. However, in this case if our switch goes down we lose connectivity to all the devices connected to it. This is where virtual port channel comes to rescue. A virtual port channel allows you to bundles physical links spread across two separate physical switches. Following figures show simple port channel and virtual port channel topologies.  In this case Switch L runs simple port channel (LACP) because this switch has no idea that it is connecting to two different switches. But wait a minute how is that possible? With above topology it is not possible. We need little more on switch A and B side so that they can dodge Switch L to appear as single switch. We need to add extra physical links between Switch A and Switch B so that these switches can inform each other that they are both working on to fool
