Hi everyone, I’m excited to share my journey of integrating server status monitoring into my OpenHAB setup. As someone who values seamless automation, I wanted to ensure that my system could notify me of critical events like overheating, low disk space, or even when the UPS kicks in. This integration not only adds a layer of security but also allows for automated responses, such as turning on the air conditioning if the server overheats.
My Setup
I’m running an OMV NAS with OpenHAB installed via Docker, along with MQTT for messaging. Initially, I found several guides online, but they didn’t quite fit my needs. After some experimentation, I managed to create a custom solution using Node.js to monitor server metrics and publish them to MQTT. OpenHAB then subscribes to these topics and triggers notifications or actions based on predefined rules.
Key Features
- Temperature Monitoring: Automatically activates the air conditioning if the server temperature exceeds a set threshold.
- Disk Space Alerts: Sends a notification if any disk is below 20% free space.
- UPS Status: Monitors battery levels and provides alerts during power outages.
- Software Updates: Checks for available updates and notifies via Pushover.
Challenges and Solutions
One of the main challenges was ensuring real-time monitoring without overloading the server. I optimized the Node.js script to run checks at intervals that balance performance and responsiveness. Additionally, setting up MQTT as the communication layer provided a reliable and lightweight solution.
Community Feedback
I’d love to hear from others who have implemented similar solutions. What tools or methods have you used for server monitoring within OpenHAB? Any tips or tricks to improve reliability or add more features would be greatly appreciated!
Happy automating!
