Hello everyone, I wanted to share my journey in creating a robust power outage management system for my Hubitat hub. This solution has been a game-changer for me, and I hope it can inspire others to tackle similar challenges.
Background:
Like many of you, I rely heavily on my smart home setup, which includes my Hubitat hub, cameras, lights, and various sensors. However, I’ve always been concerned about the potential for a power outage, especially during severe weather. While my devices are backed by UPS units, I wanted a more proactive approach to ensure my system remains operational and recovers smoothly after an outage.
The Solution: Node-RED to the Rescue
After extensive research, I stumbled upon Node-RED, an open-source flow-based programming tool. It seemed perfect for my needs. I decided to use it to monitor power status and automate the shutdown and restart of my Hubitat hub.
How It Works
-
Monitoring Power Status:
I set up Node-RED to periodically ping two devices not connected to a UPS. If both devices fail to respond, it triggers the assumption of a power outage. -
Hubitat Shutdown:
Upon detecting a power outage, Node-RED sends a shutdown command to my Hubitat hub. This ensures that the hub doesn’t drain the UPS unnecessarily and prevents potential damage from prolonged operation during an outage. -
Automatic Restart:
Once power is restored, Node-RED checks if the Hubitat hub is still down. If it is, the system restarts the hub by controlling a TP-Link Kasa smart plug connected to the hub’s power supply.
Challenges and Lessons Learned
-
Initial Setup Hurdles:
Configuring Node-RED and integrating it with Hubitat wasn’t straightforward. I had to troubleshoot several times, especially with authentication and API calls. -
Testing and Validation:
Extensive testing was crucial to ensure reliability. I simulated power outages and monitored the system’s response to identify and fix any issues.
Results and Benefits
This setup has significantly improved my smart home’s resilience. The automated shutdown and restart processes have eliminated the need for manual intervention, saving me time and reducing stress during power outages.
Final Thoughts
Node-RED has proven to be a versatile and powerful tool for custom automation. I’m excited to explore more possibilities with it. I’d love to hear from others who have implemented similar solutions or have suggestions for improvement.
Thank you to the Node-RED and Hubitat communities for their invaluable resources and support. Happy automating!
