I recently faced a challenge with my Sonoff relay operating in inching mode to control my air conditioner. The issue was that I couldn’t track the AC’s state, whether it was on or off. After some research and experimentation, I managed to create a virtual switch using Home Assistant that now tracks the AC’s state effectively. Here’s how I did it:
-
Understanding the Problem: The Sonoff relay acts as a push-button switch, turning on for a second and then off. Without a sensor to detect the AC’s state, I couldn’t determine if it was running or not.
-
Creating an Input Boolean: I started by setting up an
input_booleanto represent the AC’s state. This allows me to manually or automatically set the state toonoroff. -
Setting Up a Template Switch: Next, I configured a template switch in Home Assistant. This switch uses the
input_booleanto determine its state. If theinput_booleanison, the template switch shows ason, and vice versa. -
Automation and Integration: To ensure the virtual switch updates correctly, I set up an automation that triggers when the Sonoff relay turns on or off. This automation updates the
input_booleanaccordingly, maintaining the correct state. -
Testing and Refinement: After setting everything up, I tested the system thoroughly. Initially, there were some hiccups, but by adjusting the automation and ensuring the template switch correctly referenced the
input_boolean, everything started working smoothly.
Now, my virtual switch accurately reflects the AC’s state, and I can control it through Home Assistant and Google Home without any issues. This setup has significantly improved my smart home experience, making it more intuitive and user-friendly.
If anyone else is dealing with a similar challenge, I highly recommend exploring Home Assistant’s template switches and input booleans. They’re powerful tools for creating custom solutions tailored to your specific needs.
