While off-the-shelf smart thermostats are great, a smart thermostats DIY approach can be more powerful and educational. Using an affordable ESP32 microcontroller and a temperature sensor, you can build a thermostat that integrates directly into Home Assistant. This allows for hyper-personalized schedules, presence detection (so you never heat an empty house), and integration with external sensors placed in different rooms to eliminate hot and cold spots. This is a core tenet of Passive house smart tech, where the home’s systems work together intelligently.
DIY Smart Plugs for Energy Vampires
Many electronics consume “standby” or “vampire” power even when turned off. These small draws add up significantly. A DIY smart plugs energy project lets you tackle this head-on. You can flash off-the-shelf smart plugs with custom firmware like Tasmota or ESPHome to make them local-only and integrate them perfectly with your system. Group devices like your TV, soundbar, and game console onto one smart power strip and create an automation to completely cut power to them when you go to bed or leave the house.
DIY Smart Energy Monitoring
This is the ultimate project for understanding and optimizing your home’s energy use. A DIY smart energy monitoring system gives you real-time data on exactly how much electricity you’re using and which appliances are the culprits. You can build a system using a CT clamp sensor connected to an ESP32, or use a pre-built device like a Shelly EM. Once integrated into Home Assistant, you can create a detailed energy dashboard, track consumption over time, and set up alerts for unusually high usage. It turns energy saving into a data-driven mission.
Smart Lighting that Saves
Smart lighting energy saving is about more than just yelling at a speaker to turn off the lights.
- Automation: Use motion sensors to automatically turn lights on and off in rooms like bathrooms, hallways, and closets.
- Dimming: LED bulbs use significantly less power when dimmed. Automate lights to be at 100% during the day but dim to 30% in the evening.
- Scene Control: Create a “Movie Night” scene that dims the main lights and turns on accent lighting with a single command, using far less energy than lighting the whole room.
Water Conservation: Every Drop Counts
Water is a precious resource, and smart tech provides powerful tools for conservation.
Smart Irrigation and DIY Garden Systems
A DIY smart garden system is a game-changer for anyone with a lawn or garden. Instead of a dumb timer that runs rain or shine, a smart system pulls weather forecast data from the internet. It will automatically skip watering cycles if rain is predicted, saving thousands of gallons of water per year. For indoor or patio gardeners, you can use soil moisture sensors connected to a Raspberry Pi to create a system that gives your plants the perfect amount of water, exactly when they need it. This is a fantastic eco-conscious home tech project.
Smart Leak Detectors
A small leak can waste an incredible amount of water and cause thousands of dollars in damage. Simple, affordable smart leak detectors can be placed near water heaters, sinks, and washing machines. They can send an immediate alert to your phone at the first sign of moisture, allowing you to act fast. This is one of the simplest yet most effective eco-friendly gadgets home you can install.
A Breath of Fresh Air: Smart Air Quality Monitoring
The air inside your home can be more polluted than the air outside. Sustainable home upgrades should always include creating a healthier living environment.
DIY Indoor Air Quality (IAQ) Monitors
With components like a BME680 sensor and an ESP32 board, you can build a comprehensive IAQ monitor for a fraction of the cost of a commercial one. This device can track temperature, humidity, pressure, volatile organic compounds (VOCs), and CO2 levels. High CO2 levels can cause fatigue and headaches, while VOCs are emitted from paints, furniture, and cleaning supplies.
Automated Ventilation
Once you have the data from your smart home CO2 monitoring system, you can act on it. Create an automation that turns on a bathroom exhaust fan, an HRV/ERV system, or a smart air purifier when CO2 or VOC levels cross a certain threshold. This ensures your home is always filled with fresh, clean air without running ventilation systems 24/7.
Beyond the Basics: Advanced Eco-Smart Projects
Once you’ve mastered the fundamentals, you can explore more advanced projects that further enhance your home’s smart home sustainability.
