Streamlining Device Automation in Home Assistant

Hey everyone, I wanted to share my journey in optimizing how I manage multiple devices in Home Assistant. For those who might not know, I’ve been tinkering with smart home setups for a while now, and one of the challenges I’ve faced is managing multiple devices with different automation rules without everything getting too convoluted.

Let me start by sharing a bit about my setup. I have a variety of devices controlled by Shelly units—everything from an air dryer that shouldn’t run during my night mode to a battery charger that only kicks in when my UPS is active. Initially, I built separate automations for each device, which worked but quickly became unwieldy. Every time I wanted to change a condition, I’d have to update it across multiple automations, which was a nightmare to maintain. Plus, there were occasional issues with devices missing commands or getting stuck in the wrong state.

I decided it was time for a better approach. After some research and brainstorming, I landed on the idea of centralizing the logic for each device. Instead of having each automation handle its own set of conditions, I created a unified script that manages all the dependencies for a specific device. This way, any changes only need to be made in one place, drastically reducing the complexity and potential for errors.

Here’s a quick overview of how I implemented it:

  • Centralized Logic: I set up a single script per device that encapsulates all the conditions and dependencies. This script is triggered by various events, such as changes in solar power availability or manual inputs from my control panel.
  • Avoiding Redundant Triggers: To prevent multiple triggers from overwhelming the system, I added checks within the script to ensure it doesn’t run if it’s already executing. This has helped reduce CPU usage and those annoying log warnings about multiple actions.
  • State Enforcement: I incorporated a mechanism to periodically check if devices are in their desired state. If a device is found to be out of sync, the script automatically corrects it, eliminating the need for constant manual interventions.

The results have been fantastic! My system is now more responsive and reliable. The best part is the reduction in administrative overhead—no more chasing down errors across multiple automations. I’ve also noticed a drop in the memory usage spikes that were previously attributed to the redundant logic evaluations.

I’d love to hear how others are handling similar challenges. Whether it’s through custom scripts, services, or other innovative solutions, sharing experiences can only make our setups better. If you’ve got tips or alternative approaches, I’m all ears!

Happy automating, everyone! :rocket:
