Integrating Smart AC with Temperature Sensors

I recently faced an interesting challenge while trying to integrate my Smart AC with a standalone temperature sensor. The goal was to control the AC based on the bedroom temperature, even though the AC unit is located in a hallway. Initially, I thought this would be straightforward, but it turned out to be a fun problem to solve!

The issue was that the AC unit’s built-in sensor reads a different temperature than the bedroom sensor. After some research, I discovered that most Smart AC systems rely on their own sensors, making it tricky to use an external one. However, I wasn’t ready to give up on the idea of a seamless, integrated system.

Here’s what I did:

  1. Understanding the Problem: I realized that the AC’s built-in sensor was not ideal for my setup. The hallway’s temperature doesn’t always reflect the bedroom’s conditions, especially at night.

  2. Exploring Options: I looked into whether the AC’s API allows overriding the temperature source. Unfortunately, it seemed that most models don’t support this feature out of the box.

  3. Custom Automation: I decided to create a custom automation using Home Assistant. The idea was to monitor the bedroom sensor and send commands to the AC based on its readings.

  4. Testing and Tweaking: I set up a rule where the AC adjusts its temperature whenever the bedroom sensor detects a significant change. It took a few iterations to get the thresholds right, but it eventually worked!

Now, my system is more responsive to the bedroom’s actual conditions, and I can enjoy a more comfortable environment without the cold air blowing directly into the room at night. This experience taught me the value of persistence and the power of custom automation in solving everyday problems. If anyone has similar challenges or tips, I’d love to hear about them!
