I wanted to share my recent project where I integrated a Shelly 1 with an Arduino to monitor multiple sensors in my home. This setup has been incredibly useful and I’d love to hear if others have tried something similar or have tips to improve it further!
Project Overview:
I’ve always been curious about home automation and wanted to experiment with sensor data integration. The Shelly 1, combined with an Arduino, seemed like a perfect starting point. The goal was to monitor temperature, humidity, and light levels in different areas of my home.
Setup Details:
- Hardware Used: Shelly 1, Arduino Uno, DS18B20 temperature sensors, DHT22 humidity sensor, and an LDR for light detection.
- Integration: The Arduino processes the sensor data and communicates with the Shelly 1 addon, which then sends the data to my Home Assistant instance.
- Power Management: I initially powered the Arduino separately but later switched to using the Shelly addon’s DC/DC converter for a cleaner setup.
Current Configuration:- Temperature Monitoring: Using up to three DS18B20 sensors to track temperature variations across the house.
- Humidity and Light Detection: The DHT22 provides accurate humidity readings, while the LDR offers real-time light level data.
Benefits So Far:- Centralized Monitoring: All sensor data is now accessible through the Home Assistant app, making it easy to track environmental conditions in real-time.
- Automation Opportunities: The data collected is being used to trigger automated actions, such as adjusting lighting based on natural light levels or activating fans when humidity rises.
Challenges and Solutions:- Power Supply: Ensuring stable power supply was crucial. Using the Shelly addon’s built-in converter simplified things and reduced the number of external power sources.
- Data Accuracy: Calibrating the sensors initially was a bit tricky, but once set up, the readings have been consistent.
**Future Plans:**I’m looking to expand this setup by adding more sensors, possibly including air quality and pressure sensors. The Arduino’s flexibility makes it easy to integrate new devices as needed.
**Tip for Others:**If you’re considering a similar project, start with a single sensor to test the integration before scaling up. This approach helps in identifying and resolving any issues early on.
Would love to hear about your experiences with sensor integrations or any improvements you’ve made to similar setups!
