Hey everyone! I wanted to share a really positive experience I’ve had setting up my home automation system with Hubitat Elevation. I’ve been working on automating my window AC units, and I’m thrilled with how it’s turned out. Let me walk you through what I’ve done and some tips that might help if you’re looking to do something similar.First off, I’ve got Zooz Z-Wave Power Outlets connected to all my window AC units—let’s call them AC A, B, C, and D. These outlets are perfect because they allow me to control each AC unit individually right from my Hubitat setup. I also have zigbee temp sensors in each room (temp A, B, C, D) and one in an intermediate location (temp E). The goal was to create a smart system that not only regulates the temperature but also allows for manual overrides and integrates seamlessly with my Alexa devices.For the automation part, I set up two main rules for each AC unit. The first rule is straightforward: if the temperature in a room (say, temp A) rises above a certain threshold (X), the corresponding AC unit (AC A) turns on. The second rule is a bit more nuanced: if the temperature drops below a set level (Y) and the AC unit’s current usage is below a certain threshold (Z), the AC turns off. This helps prevent the AC from turning off mid-cycle, which can be inefficient.But the real magic comes with the override rules. I wanted to make sure that even if the automated system is running, I could manually control the AC units if needed. For instance, if temp E (the intermediate sensor) detects a higher temperature, I can override the system to turn on ACs A, B, and C regardless of their individual room temperatures. This is especially handy during heatwaves when I want to ensure all areas are cooled efficiently.Another fantastic feature I’ve integrated is Alexa voice control. Now, if I say, “Alexa, turn on AC A,” it does so immediately, bypassing the automated temperature controls. Similarly, I can disable all AC units with a simple voice command, which is super convenient, especially when I’m not home and want to ensure everything is off.Setting this up wasn’t without its challenges. One thing I learned was the importance of accurate temperature sensing. I had to experiment with the placement of my temp sensors to get the most reliable readings. Also, ensuring that my Hubitat setup was correctly configured to communicate with both the Zooz outlets and the zigbee sensors was crucial.I’d love to hear from anyone else who’s done something similar or has tips on improving this setup. Automation has completely transformed how I manage my home’s comfort, and I’m excited to see how I can expand this system further in the future. Happy automating everyone!
