Hello everyone! I wanted to share an exciting update on my DIY indoor grow chamber project, which I’ve been working on using the Pico-Relay-B board. This project has been a fantastic way to explore the capabilities of smart home automation while nurturing my green thumb. Here’s a quick rundown of where I am now and some tips I’ve picked up along the way.
Project Overview
The grow chamber is controlled using Esphome, and this is just the first working prototype (v1.0). The setup is designed to maintain ideal growing conditions in a compact indoor space. Right now, the system uses eight relays to control various aspects of the environment, such as lighting, fans, and water pumps. I’ve documented the entire process, including the wiring setup, which I’ve shared below:

Key Learnings and Tips
-
Wiring Simplification: As a newbie to electronics, I kept the wiring details as minimal as possible. If you’re looking to replicate this setup, I recommend starting with a similar board and its wiring diagram for reference. Here’s a link to a similar board for those interested: Industrial 6-Channel ESP32-S3 WiFi Relay Module.
-
Hydroponic Integration: I’m using a hydroponic port from this Tuya WiFi hydroponics kit: Tuya Hydroponics Kit. It’s been a great addition to the system and fits perfectly within the chamber’s design.
-
Future Plans: My next step is to add environmental sensors like temperature, humidity, and CO₂ to automate the chamber’s power based on real-time conditions. If anyone has experience with similar setups or suggestions, I’d love to hear from you!
Challenges and Solutions
One challenge I faced was ensuring the chamber fit both the hydroponic unit and a small fridge. After some trial and error, I found a design that works well. If you’re planning a similar project, I recommend starting with a clear layout and testing each component individually before integrating them.
AI Assistance
Since I’m not a native English speaker, I used AI to help translate and refine this post. If anything seems unclear, please let me know, and I’ll do my best to clarify!
Closing Thoughts
This project has been a fantastic learning experience, and I’m excited to see how it evolves in the coming months. If you’re considering a similar DIY project or have questions about automating your grow space, feel free to reach out. I’d love to hear your ideas and help where I can!
Happy growing!
