Hey everyone, I wanted to share a fun DIY project I recently completed—a smart shower system! 
It was a bit of a challenge, but the result is fantastic. Here’s how I did it:
The Goal:
I wanted a hands-free shower experience that I could control with my phone or voice. Plus, I wanted it to be energy-efficient and safe, even during power outages.
The Setup:
- Electrical Junction Box: To house all the components safely.
- Sonoff Basic Switch: To control the power supply.
- 24VAC Transformer: To step down the voltage for safety.
- Irrigation Valve: To control the water flow.
- WYZE Reed Switch: To detect when the shower door is open.
- Misc Plumbing Fittings: To connect everything neatly.
How It Works:
- The Sonoff switch activates the transformer, which powers the irrigation valve.
- The valve is connected to the shower head, allowing water to flow when activated.
- The reed switch on the shower door detects when it’s opened, automatically turning off the water and lights.
- I added a recessed light above the shower for better visibility—definitely a nice touch!
Challenges and Solutions:
- Power Outage Concerns: I decided to add a manual bypass valve so I can still enjoy a shower if the power goes out.
- Temperature Control: While I couldn’t automate temperature adjustments, I set the valve to my preferred setting and leave it there.
Results:
It’s been a week since I installed it, and I’m thrilled with how it works! The system is reliable, and the hands-free feature is a huge convenience. Plus, the energy efficiency is a bonus.
Future Plans:
Now that the shower is sorted, I’m looking into automating my bedroom door. Imagine being able to open it with Alexa while still maintaining manual control—pretty cool!
If you’re thinking of tackling a similar project, I’d recommend starting small and testing each component before integrating everything. And don’t hesitate to reach out if you have questions—I’d love to help!
Cheers, Derek
