You can create rules on Node-RED and schedule events to make things happen automatically. For example, turn something on or off depending on sensor readings, day and time of the week, etc. InfluxDB provides tools to build customizable awesome charts and graphs to display and monitor your data on a dashboard.

In his spare time, he enjoys hiking, photography, cooking, and starting countless DIY projects he has yet to complete.
MODULE 4: Introducing the ESP32 and ESP8266 Boards
With Node-RED you can spend more time making cool stuff, rather than spending countless hours writing code. Smart plugs are budget-friendly, easy to use, and turn virtually any appliance or electronic into a smart device. After setup, you can use an app to set timers and schedule lights. The Wemo Mini (about $25) has a compact size that won't block the other outlet. Wemo also has an away mode to make it look like you're home, even when you're on vacation. There are thousands of ways to automate your home—making it easy to go overboard on smart devices you don’t need.
Seriously, that’s why I offer a 60 days money back guarantee. Email me here and I will promptly refund all your money. If you can’t get a Raspberry Pi, you can still follow along and build your home automation system on the cloud, which requires a monthly payment for the hosting service. If there’s something extra that you need to learn during the eBook, we’ll point you to the right resource. Use charts and gauges to visualize sensor readings. Use MQTT to communicate between Node-RED and other devices .
Devices for starting a smart home
We suggest starting slowly with one or two smart devices before gradually adding more. Press Add and the MQTT output node automatically connects to your broker. Now only devices with username and password can connect to your MQTT broker. Unit 5 - MQTT Authentication with Username and Password In this Unit, I’m going to show you how to setup an authentication mechanism with MQTT. I will use basic authentication with username and password. You could potencially setup a full encrypted secured connection with TLS, but it is a bit more complicated and it’s not the purpose of this tutorial.
Hubs are also great for reducing the number of Wi-Fi devices on your home network if they're slowing down your internet connection. While you want to maximize your devices' compatibility with each other, you won't find a single smart home system that works with everything. For now, your best bet is to use devices that work with multiple smart home platforms. The biggest dilemma in the smart home is which platform to use. Using a single platform, your devices can talk to each other and you can control them in a central place. A smart thermostat boosts your home's comfort and energy efficiency.

You can minimize threats by sticking with trusted manufacturers, using strong passwords, and setting up two-factor authentication if available. Check out our guide to protecting your smart home from hacking for more tips. Exporting Now with the nodes highlighted, you open the top Menu, go to Export and select Clipboard. Unit 1 - Creating Master Switches or Modes In any home automation system, it’s useful to create specific modes tailored for your home. For instance, it’s handy to press a button that turns on/off all the lights in your home. With Node-RED this can be accomplished with what I call a master switch.
About raspi-config Most configurations are pretty self-explanatory and for this course you only need to change one setting . This is a very brief tutorial that shows how to edit a file and save it using the nano program. The nano is way more powerful and has a lot of shortcuts that you can use to your advantage, but those go beyond what you need to know to complete this course. You can always refer to the official documentation or use the built-in Help menu.

Build Web Servers with ESP32 and ESP8266 »boards to control outputs and monitor sensors remotely. Node-RED and InfluxDB are free to use locally on your Raspberry Pi. You don’t need to pay anything to use that software. In Module 9, if you want to access your Home Automation System outside your local network, you’ll need a domain name. You can use a free domain name or you can get a paid domain name in order to create a secure tunnel with Cloudflare.
Setup In the setup() function, you need to set the LED as an OUTPUT and the motion sensor is set as an INTERRUPT that is activated in RISING mode. The motionTriggered control variable is used to trigger the notification message to the Node-RED Dashboard just once. So you can send commands from the Node-RED Dashboard to arm/disarm the smoke sensor. Throughout this Unit you’re going to use the DHT11 sensor. Setup_wifi The setup_wifi() function connects your ESP8266 to your router and you don’t need to modify anything.
Learn Raspberry Pi, ESP8266, Arduino and Node-RED. If you would like the longer version of my story, you can find it over here. Needs to review the security of your connection before proceeding. Home Automation using ESP8266 eBook and video course » Build IoT and home automation projects. We use Raspberry Pi to run Node-RED, Mosquitto MQTT broker, and InfluxDB locally.
However, you can add as many as you want and extend this project to other rooms in your home. Creating the Flow In this flow, you’re going to turn your outlets on/off according to a threshold value. Unit 5 - Triggering Outlets with Temperature and Luminosity This Unit shows you how to trigger your outlets based on sensor values that you define.
Routines group device functions together under a single command—some companies call them scenes or shortcuts. This allows you to change multiple settings at once to skip the burdensome and slow process of using manual controls one by one on a smartphone app or smart speaker. Unit 2 - Triggering Time-based Events Having a great home automation system means that you should be able to make something happen without having to touch a single button. There are certain routines in your home that could automated. You should add time-based triggers to your home automation system to meet your specific needs.
You simply connect an E27 lamp to the E27 remote controlled holder. Reconnect The function reconnect() reconnects your ESP to your MQTT broker. Set the On Value to “1” and the Off Value to “0“. Then, it configures the module with your own credentials . You actually need to replace those 3 variables with your credentials, so that your ESP8266 can connect to your network and MQTT broker.
Before you know it, you’ll be living in a twenty-first-century smart home. Open Node-RED Dashboard When you go to the Config tab in the UI, it shows two new buttons. If you press the first button your Raspberry Pi immediately powers off safely and when you click the second button the RPi reboots.
In the center, you have the Flow and this is where you place the nodes. Node-RED is a powerful open source tool for building Internet of Things applications with the goal of simplifying the programming component. It uses a visual programming that allows you to connect code blocks, known as nodes, together to perform a task. Read Mac OS X/Linux Version SSH is a method of establishing a communication with another computer securely. SSH is based on a Unix shell, so it allows you to access your Raspberry Pi files from a remote machine by using terminal commands.
