An analog home was yesterday – today the smart home is the trend. There are countless solutions for this on the market from well-known and large providers. But also every ambitious maker can make his own home smart with a little knowledge and for little money. On Pollux Labs you can find many projects that you can create with your Arduino or ESP8266/ESP32.

The right microcontroller

When choosing the board for your smart home project, you should consider in advance which functions you need. For simple projects, an Arduino might be enough. However, if you want to access your home via the Internet, an ESP8266 or ESP32 are of course better choices.

Smart Home with the Arduino

“Smart” doesn’t have to mean that you control something from your smartphone. Maybe you just want a plant monitor that gives an audible or visual signal when the soil of your favorite plant is too dry. Or lower the shutter when it’s too warm in your home.

In these cases, just an Arduino Uno and the right sensor can do the trick. How about a weather forecast, for example? Pretty smart too, right?

Projects with the ESP8266 and the ESP32

But if you want to control something from “outside”, then you can’t get around an internet capable microcontroller. Popular and proven are of course the inexpensive ESP8266 and the more powerful ESP32. The latter also has Bluetooth in addition to Wi-Fi.

With these controllers, you can create a web server or a project whose data can be retrieved from your smartphone in no time at all.

Popular smart home projects

Some topics are particularly popular, for example lighting, sensor data, remote control and monitoring. On Pollux Labs you will find many projects suitable for beginners and advanced users.

Control lighting in your smart home

You forgot to turn off the lights when you left your house? No problem: Just turn it off with your smartphone while you’re on the go.

In our project Switch the light on and off with Telegram, you’ll learn the basics of controlling a light with your smartphone. Here you’ll use a simple LED, but you can easily replace it with a relay. This way, you can also turn a real light bulb on and off.

But what if you don’t want to control the light yourself? Then give your smart home some atmosphere by letting the International Space Station or the moon do it for you. I beg your pardon? Yes, it works.

On Pollux Labs you’ll find two matching projects:

Request sensor data

Want to know how warm it is at home while you’re freezing in the cold? Or the other way around, if you should turn on the air conditioning?

With your ESP8266 and a temperature sensor you can do that easily. On Pollux Labs, for example, we have a project with a BMP180 whose data you can request from anywhere in the world using the Telegram app.

But you don’t necessarily have to do it yourself. You can, of course, get notified when the temperature exceeds a certain limit.

An ESP8266 or ESP32 is also suitable for setting up a web server – here you can create an entire dashboard for analyzing the most important data from your smart home on the go.

Monitoring your smart home with the ESP32-CAM

How about a view into your home from anywhere in the world? With the ESP32-CAM and Telegram this is no problem. For example, you can create an alarm system that sends you a photo to your smartphone when it is triggered by a burglar (or even your cat).

You can also create a video live stream with this microcontroller, so you can watch what is going on in front of the camera lens.

Please note that these projects do not violate any personal rights. You should also be aware of possible IT security gaps with all smart home projects.
