Setting Up The Home Automation Server (OpenHAB 2 + MQTT)

The first thing I will show you is the device in action so as you can see here it is and it is mounted on the same wall as the network. But, you might be wondering what it is doing right now well, right now it is hosting the OpenHAB 2 service as well as the mqtt service. After completing this series we will be prepared and ready to create the user interfaces as well as connect our smart automation devices.

Now let’s talk about how it all works. To start off the entire thing is running on a raspberry pi, in this case I am using a raspberry pi 3 but this will work fine on a 2 as well as anymore pi’s in the future. Next up the storage for the pi is a 32gb sandisk micro sd card class 10 of course for the extra data speed. The pi is being housed in a clear acrylic case with a fan built in. But the fan does not do the cooling on its own, I have also installed a heat sink which with the fan is pretty good cooling. The pi is being powered by a 5v 2.5 amp power adapter that is UL certified which is important for power stability. The actual pi is connected to the network via a green cat 6 cable. We will be installing the software onto the pi using either a Mac computer or a windows computer which each have their own video so when you do it make sure you watch the right video. The software we will be installing is OpenHAB 2 as well a Mosquitto Mqtt server. But, this has all been made easy because all we will be doing is flashing a prebuilt image called openHABian which makes everything a lot easier. To actually configure the pi we will be using a combination of the web browser and ssh. But, the entire software process will be explained in its respective video.

That’s all I have for the actual demo, now it is time for you to watch the next videos to learn how to setup your own home automation server running OpenHAB 2.

Installing the heatsinks onto the raspberry pi:

  1. Peal the backing off of the smaller heatsink
  2. Take the smaller heatsink and place it on the small black square on the raspberry pi
  3. Align the heatsink and then press down on it to make sure it attached
  4. Peal the backing off of the bigger heatsink
  5. Take the bigger heatsink and place it on the big black square on the raspberry pi
  6. Align the heatsink and then press down on it to make sure it is attached

Setting up the case:​

  1. Take off all the protective acrylic packaging paper off of the acrylic pieces of the case (Use a knife to pick at a corner and pull off the plastic)
  2. First take bottom piece, the one with the box in the center and the long side with the shorter distance of the side to the box facing you
  3. Take out the 4 screws, 4 plastic washers and 4 nuts from the bag
  4. Take the 4 screws and put them into the bottom plastics piece from underneath with the long side with the shorter distance of the side to the box facing you and place on flat surface
  5. Take the 4 plastic spacers and put them on the screws
    Take the raspberry pi and put it on the screws by ligning it up
  6. Take the 4 nuts and put them on the screws
  7. Take out the 4 nuts and 4 screws out of the bag
  8. Take the top piece of the case and lay it flat with the gpio cut facing away from you and the big lift tabs to your left
  9. Lift up the piece and stick in the 4 screws underneath the piece and through the holes
  10. Take the fan and look around its sides to find two arrows
  11. Orient the fan so the arrow is pointing up and where the cable exits the fan should be away from you
  12. Take the fan and place it on the 4 screws
  13. Take the 4 nuts and screw the fan down
  14. Use a philips screw driver and a wrench or pliers
  15. Take the two long side pieces for the case and put them on
  16. 5v fan so plug the red side into pin 4 and black side into pin 6
  17. But sadly the case does not fit with the connector how it is so we are going to shave off the side clip with a razor or knife then plug it in
  18. Take the cable and sort off wrap it around the fan, and place the top piece in the two holes of the side pieces
  19. Take the piece with two holes in it and align it over the front ethernet and usb ports, when you put on the piece first hook it over the top hooks and then the bottom clips
  20. Then take the final piece and put it over the back, by hooking it on the top and cliping it in
  21. Now the case is complete

Setting it up for use:

  1. Plug in the ethernet cable into your network and into the raspberry pi
  2. Plug in micro usb side into the raspberry pi but not into the wall socket yet
