Vertical Blind Automation Success Story with Zemismart and Soma

I’m thrilled to share my recent success in automating my patio door’s vertical blinds! After months of planning and some trial and error, I finally got everything working seamlessly. Here’s how I did it, in case anyone else is tackling a similar project.

The Challenge
My patio door had always been a bit of an eyesore because of its manual blinds. I wanted to integrate it into my smart home setup but faced a few hurdles. The blinds needed both tilting and sliding functionality, and I didn’t want to compromise on reliability or aesthetics.

The Solution
I decided to combine a Zemismart Zigbee curtain rail for the sliding motion and a Soma Tilt 2 for the tilting. To control the Soma device, I used a Raspberry Pi Zero W running the Soma Connect software. The key was integrating both devices into a single automation flow within my Hubitat setup.

The Process

  1. Hardware Setup: I installed the Zemismart rail and connected it to my Zigbee network. The Soma Tilt 2 was mounted on the blinds, and I made sure the Pi Zero was within range.
  2. Software Integration: I wrote a custom driver to handle the communication between the Zemismart rail and the Soma device. This allowed me to send commands to both devices simultaneously.
  3. Automation Logic: I added checks to ensure the Soma device received the tilt command before the rail started moving. A small delay was crucial to prevent any mechanical conflicts.
  4. Testing: I ran through multiple scenarios, adjusting the tilt angles based on how far the blinds were open. This ensured they never over-tightened or misaligned.

The Results
The end result is nothing short of amazing! The blinds now tilt to 100% open when the rail starts moving and reset to 0% once they’re in position. It’s all smooth and automatic, and I couldn’t be happier with how it turned out.

Tips for Others

  • Plan Ahead: Sketch out your setup and consider how the devices will interact mechanically.
  • Test Incrementally: Start with basic commands and gradually build up to full automation.
  • Use delays: They might seem minor, but they can make a big difference in preventing mechanical issues.

I’d love to hear if anyone else has tackled a similar project or has tips to share. It’s been such a rewarding experience, and I’m excited to see what other automations I can come up with next!
