arduino zigbee home automation
Today I have been working on this project for a while, and finally, here is the first video. I guess home automation is in early Stages, So I started to do some research and finally came to the conclusion that I have to build one myself Here: it is. This is a small setup., I’m still developing these little boards. So let me explain.. What do we have here? So I have Alexa here hooked up to my network.. I have this Development board that is hooked up to my computer To this programmer. I have this small ESP8266 Version. 01 chip. I have a relay that is hooked up.. This is already flashed with the program I’m going to ask Alexa to discover devices on my network and It will going to discover this device, and then I will give commands to turn this device on and off. You should see this led light going on and off, And here this relay, so this relay is for demo purposes I’m planning to use solid state. Relays. I’ll go through a little bit, so let’s get into the demo So I’m going to give a command to Alexa. To discover devices and it’s going to go and discover this device on my network Alexa discovered devices Starting discovery. This can take up to 20 seconds. If you have philips, you press the button on your bridge So I’m going to wait. It takes a little bit time. So, even if you have one or multiple devices, they will discover it.
Discovery is complete. I found one smart home device if your philips bulbs were not discovered. Please press the button on the bridge and rerun discovery. So now we did discover this device on my network. So now, I’m asked I’m going to give commands and I’m going to ask Alexa to turn these on and off, so let’s Give it a command to turn it on, and you should see a clicking noise from this led. I mean clicking noise from this relay in This led should turn on Alexa turn on Master bedroom. Ok, So, as you can see, this light is on now, so I give a partial command so I’m going to go full command now, Alexa turn off Master bedroom fan. Okay, So, as you can see, the commands don’t need to be full formatted in the way they’re Flashed into the device that could be partial as long as they’re a match. It will work, otherwise They will ask you which one to turn on and off. So this is very simple setup here so I’m using a program into program, this ESP8266 – And this is very nice.. I prefer these on instead of Arduino devices, because the form Factor and also the Onboard Wi Fi. If you look at the Arduino, if you look at the Arduino board now This is Arduino. Nano and doesn’t have wi Fi. So for you to hook it up to your network., You need Wi Fi. You can actually use Arduino with the ESP8266 to provide Wi Fi functionality, but since it has a Programmer chip on it, so you can flash it and put your own programs So I’m using this instead, because the program size is very small.
, I mean you can solder In more memory on it, if you need more space, I bought a couple of these to experiment with, and I was very happy.. I mean if you look at the size with Arduino you know.. I mean this is a very small form factorso. I got this and this has has two gPio Connectors and They’re, not enough Because I’m trying to set up You know, fans and lights with, like sort of like a 3 way, switching kind of thing. So if I physically turn on and off of device, I mean our appliance. I want This device to know that that is turned on and off and then, if I use Alexa to do it, So I want to be able to have it both ways. So so two gpio s are only good for one device, so I started looking and I found this one. This is ESp8266 12 E version and it has a lot more gpio Connectors on it. As you can see, let me see if I can close in so This is so I really like this one, so this is better So now I can hook up as many devices as the number of Gpio s are on this one, And if you look at It that the form factor is much smaller than the zero one version, so one is a small form factor, so I can package this little small device and Put it into you know to the wall socket and be able to have it invisible.
This is not to know that the device is there and then you control it through Alexa. I’m planning to have these Alexa devices embedded throughout the House And also planning a kill switch for them. So if I want to shut them down at the same time, so I can have turn off and on at the same time. So let me walk you through some of the stuff.. I have so this a Mechanical relay and you can hear clicking noises when it turns on and off So I started looking.. I saw this relay. It’s a pretty big hefty relay if you need to control a big load As if you look at it. It’S, like It operates between three to Thirty two volt DC and it can handle 380 Volts, Ac and It’s rated, for I think 40 amps Yeah. So this is something if you want to really control something heavy duty. Also, I looked at this, so this is the one I’m planning to use. This is related up to two amp. So this is really nice It’s, a solid state relay the form factor is really small and you can fit multiple of them on a board, and then you can, you know, put them inside the socket and it’s easy to put them in. I Also started looking at some power supplies.. This is a small, cheap power supply.. I have three of them. I started experimenting because these relay require fireballs and then esp Boards they’re quite 3.
3., Volts to operate so there’s a different size. So I got few 3.3 volt power supplies and then some 5 volts and I order some Voltage regulator to drop it down to 3.3 volts. So see if I can use 5 volt power supply and drop it down to 3.3 volts and get this working also got A couple of different other power supplies or package recognized me, so you know there’s a less fire hazard and stuff compared to these ones. They’re, really cheap, So I’m going to be Playing around some of these Things. These are some of the sensors I’ll be using community. In temperature sensors with these devices, so we’ll probably go through all these, So this demo.. I wanted to show you just what I’ve been working on and Let me walk you through some of the board’s. I will be using Audrina.. You know Audrina Nano ESp8266 version, one 4x Berryman ESp8266 version 12 FtDI USB to TTL programmer and raspberry Pi. These are the board’s we will be playing around throughout the series based on what kind of project is, if it is, a Media Center will be using raspberry. Pi or if it’s a hub for the iot devices, if this individual switches and Devices that we need to control to Alexa or the smartphone will be using ESp8266 version, 1 or 12 based on how many Gpio s we need so here’s a Carbon monoxide sensor, they’ll, Be using Carbon dioxide sensor relay to control Devices distance sensor I’ll be using these to Open and close garage doors or detect if the garage door Open, close garage doors and detect.
If the garage door is open and close Ir sensor and Transmitter and receivers to control TV DVD player Receiver, here are some of the projects that I plan to do. Control garage doors through Smart phone and Alexa control, lights and van for each room with smartphone and Alexa, monitor temperature, humidity, Carbon Dioxide, Carbon monoxide For each room – and this is not limited.. There are some other sensors that I’m planning to put in, but we’ll one. We do When we do this project, we’ll walk through them, but these are some of the projects that I’m planning to do essential, lasing heating control with Alexa. So for this project. I’m going to see if I can hook up to the existing honeywell controller and hook that to Alexa Using the ESp8266, if not, we may I – I may have to get something off: the shelf control TV, PS4, Xbox and receiver in each room With Alexa, Especially for the game room or what I want to do is I want to set it up. So if I give a command to Alexa to turn on, PlayStation 4 surround sound, so it should turn on my receiver., Which is a 7.1 surround sound speaker system with the TV and Playstation 4 and Same thing for goes for Xbox. If we want to just play PlayStation on the TV Not using surround sound, so I should have a different command and it should just turn on the TV in PlayStation 4, so that’s.
What I’m looking for to do? Pi 3 media Server controlled by Alexa and smartphone I’ll, be trying different XBMC Like Kodi version or some other to see which one we can put on and then we can control it. So Alexa, You know selecting a movie or something like that: Build automation and dashboard. In the cloud so basically going to build an app in the cloud That you can access it through any device from anywhere plant watering sensor for indoor plants. So we have indoor plants in different Shapes and sizes and we want to set up some kind of jig. In there That’s invisible hidden behind the plants and a holds the water, and if we’re away, We can program it, so it can detect the dirt in soil. You know how dry it is and it can water it so Develop. Custom Alexa skills. So this is a very important part of this planning. All the Alexa skills they’re out there.. They are designed for specific user purpose, so we’re going to take a look at it. If something that does not fit. What we want We’re going to go ahead and build Alexa skills ourself and see if we can incorporate some of the stuff we want. So that is it for this tutorial, So next tutorial, we’ll start. Take a look at the ESp8266, how we can flash the ESp8266 and hook it up to our network and Use Alexa to control it on and off So we’ll.
Have this Detail step by step tutorials? So anybody who is even new with electronics should be able to follow it. So please, let me know what you think.
