Main sections On the left-side, you can see a list with a bunch of blocks. These blocks are called nodes and they are separated by their functionality. If you select a node, you can see how it works in the info tab.

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.

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.

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.

Creating a simple flow Let’s test a simple example of a flow. Running Angry IP Scanner Now, run the Angry IP Scanner. When you launch the software, it should automatically pick the IP Range for you network, so all you need to do is press Start and wait a few seconds.

MODULE 11: Setting up a Surveillance Camera

If a sensor reading goes below a certain threshold value, it automatically turns your light on or off. In the next Unit, you’re going to see the final demonstration to quickly recap all the features and see the project in action. Project Box Enclosure Finally, I’ve bought a project box enclosure to store my final circuit. This prevents your ESP from having power issues when connected to a USB port . The next variable is used to create a timer that keeps checking the smoke value every few milliseconds. If you plug them to an outlet, you should be able to control the remote controlled outlets with your remote control.

Unit 3 - Testing the Installation To test the ESP8266 add-on installation, let’s see if we can blink an LED with the ESP8266 using the Arduino programming language. Installing Arduino IDE Grab the file that you have just downloaded and open the Arduino IDE application file . Programming the ESP8266 with Arduino IDE There are a few ways of programming the ESP8266. In this course you’ll program your ESP using the Arduino IDE software.

Over the years, but Instructables user electronichamsters shows off one of the most complete systems we've seen yet. With it, you'll be able to monitor just about everything in your house. I’ll be publishing new ESP8266 guides and projects this week on the RNT Lab! To manage your software, you need the authorization of the administrator, whom you already know as the superuser.

Setting the RF Channels I’ve set my remote control to the I position. There are also E27 Lamp Bulb Holders that are controlled with an RF remote. They should also operate at 433MHz and they work like the outlets.

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.

MODULE 7: Sending Notifications with Node-RED

Unit 5 - ESP8266 Final Demonstration So, let’s quickly recap what we have accomplished so far. Inside the project box, we have a Raspberry Pi hosting the Mosquitto Broker and the Node-RED software. We also have an ESP8266 being powered through the Raspberry Pi USB port. You have to define the type of DHT sensor that you’re using. In my case, I’m using the DHT11, but if you’re using another version you can comment the DHT11 line and uncomment your sensor version. Unit 3 - Controlling Lamps and Outlets with ESP using MQTT It’s time to control the outlets with Node-RED Dashboard .

The ESP826-12E that has built-in programmer is the best option right now. The builtin programmer makes it easy to prototype and upload your programs.

Watch the quick video demonstration of the Node-RED Dashboard receiving the messages from your ESP8266. In the next couple of Modules, you’ll start programming the ESP8266 and connect it to your Raspberry Pi to control outputs and monitor sensors. As you can see, my router is located almost in the center of my home. You need to assure that all the devices can establish a stable wireless communication with your router. Go back to the Node-RED software and drag two rpi-gpio out nodes to your flow.

For example, when you send a request to IFTTT, it triggers a recipe that sends an email alert or notification. So you can send commands from the Node-RED Dashboard to arm/disarm the motion sensor. Callback Inside the callback() function, you receive commands from the Node-RED Dashboard to actually arm/disarm the smoke sensor. You can buy a wireless booster to extend the wireless signal of your router.

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.

At this moment, the Node-RED Dashboard is only accessible when you are connected to your network. Luckily, in just a few minutes you’ll be able to control and monitor your home from anywhere. Callback Inside the callback() function, you receive commands from the Node-RED Dashboard to actually arm/disarm the motion sensor.

They're helpful for manually starting devices on demand, like when you want more light in the kitchen. Automations use a cause/effect structure that allows devices to react automatically to changing conditions in your home. While they have a longer setup process and require more critical thinking than routines, they're the pinnacle of smart home convenience.

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.

For example, it can shift your house’s temperatures higher or lower during periods of low activity (like when you're asleep or away). Our favorite smart thermostat is the Nest Learning Thermostat (about $250) because it learns your preferred temperature settings and programs itself. Smart light bulbs are one of the cheapest and easiest ways to start automating your home. While we like multicolor light bulbs for their flexibility, we think the Philips Hue White A19 LED Smart Bulb is a good starting point (for around $15). It's easy to schedule and dim using a mobile app or your voice. It doesn't support multiple colors but is an affordable option from one of the best smart home brands.

For example, adjust a smart bulb to the right brightness and color to set the mood as you curl up with a good book. A smart hub is traditionally a device which controls other devices through protocols like Z-Wave and Zigbee. Although this type of tangible hub still exists , it's becoming more common to see virtual hubs that link accounts of different Wi-Fi devices over the internet . While a security camera's primary goal is to record events in and around your home, they can also act as a video intercom thanks to two-way audio. The Arlo Pro 4 (about $200) is one of our favorite security cameras because it boasts excellent video quality and is compatible with tons of smart home devices.
