I’ve always been fascinated by the idea of automating my home, especially when it comes to something as practical as window blinds. After spending countless hours researching and experimenting, I finally managed to integrate my Superrollo GW60 electric blinds with Home Assistant using an ESP8266 module. Here’s how I did it, in case you’re looking to embark on a similar project!
The Challenge
I came across the Superrollo GW60 series, which is known for its affordability and reliability. However, the remote control that comes with it is basic and lacks smart features. My goal was to enhance this remote using an ESP8266 module so I could control my blinds seamlessly through my smartphone or voice commands.
The Solution
The key was to reverse-engineer the communication protocol between the remote and the motor. After some trial and error, I discovered that the remote uses a HCS361 chip to encode commands. By soldering wires to the chip’s pins (S0 to S3), I was able to send the same commands through the ESP8266, which acts as a bridge to Home Assistant.
Step 1: Hardware Setup
- ESP8266 Module: I chose the AZDelivery D1 Mini NodeMcu for its compact size and compatibility with Tasmota firmware.
- Wiring: I carefully soldered four wires to the HCS361 chip’s data pins (S0 to S3) and an additional ground wire for stability.
Step 2: Firmware and Configuration
- Tasmota Firmware: Using the Tasmotizer tool, I flashed the ESP8266 with Tasmota firmware. This allowed me to configure the GPIO pins and set up MQTT communication.
- MQTT Integration: I configured Home Assistant to listen to MQTT commands from the ESP8266. Each command corresponds to a specific action (open, close, stop) on the blinds.
Step 3: Testing and Automation
- Testing: I used the Tasmota web interface to manually send commands and ensure everything worked as expected.
- Automation: I set up routines in Home Assistant to automatically adjust the blinds based on sunrise/sunset times and weather conditions.
The Outcome
The result is nothing short of amazing! I can now control my blinds with precision, schedule them to open/close at specific times, and even integrate them with other smart devices in my home. This project not only enhanced my home’s automation capabilities but also gave me a deeper understanding of how these systems work together.
Final Thoughts
If you’re looking to upgrade your home automation setup without breaking the bank, I highly recommend exploring DIY projects like this. The satisfaction of seeing your vision come to life is truly rewarding. Happy tinkering!
