I recently embarked on a project to integrate two Shelly 2 devices to control my roller shutters in Home Assistant. The journey was a mix of excitement and a few bumps along the way, but I’m thrilled to share my successful setup and some tips for anyone looking to do the same!
First, I wanted to ensure that both shutters could be controlled individually. After some research, I discovered that using MQTT integration was the way to go. I configured each Shelly device with its own MQTT topics, ensuring that commands and status updates were properly routed. This setup allowed me to control each shutter independently, which was crucial for my needs.
One challenge I faced was getting the position control to work for both shutters. Initially, only one shutter reflected its position accurately in Home Assistant. After some troubleshooting, I realized that the MQTT topics for position control needed careful attention. I made sure that the position_topic and set_position_topic were correctly set for each device, and I adjusted the value_template to correctly interpret the position data from the Shelly devices.
Another important step was calibration. I followed the Shelly documentation to calibrate both shutters, ensuring that the position sensors were accurate. This step was essential for precise control and gave me confidence that the shutters would operate as intended.
I also explored the use of Home Assistant automations to enhance the functionality. For example, I set up an automation that closes the shutters at sunset and opens them at sunrise. This integration with the built-in sun events in Home Assistant added a layer of convenience that I truly appreciate.
For anyone looking to replicate this setup, here are a few tips:
- Double-Check MQTT Topics: Ensure that each device has unique and correctly configured MQTT topics to avoid conflicts.
- Calibrate Properly: Spend the time to calibrate your devices accurately. This step significantly improves reliability.
- Use Automations: Don’t hesitate to leverage Home Assistant’s automation capabilities to create seamless integrations with other devices or services.
Seeing both shutters operate smoothly and accurately in Home Assistant was a rewarding experience. It not only enhanced my home automation setup but also gave me a deeper understanding of MQTT and device integration. If you’re considering a similar project, I highly recommend giving it a try—it’s a fantastic way to add functionality and convenience to your smart home!
Happy automating!
