I recently set up a Salicru SPS SOHO+ 500 VA UPS to protect my home lab, and I wanted to share my experience integrating it with Home Assistant. The process was a bit challenging, but the end result is fantastic!
First, I connected the UPS to my Proxmox VE server using a USB-to-RS232 adapter. The UPS communicates via the SmartApp protocol, which was straightforward to configure using the nut package. Once the UPS was recognized by the system, I set up monitoring for battery status, charging, and any potential issues.
Next, I integrated the UPS into Home Assistant using the MQTT integration. This allowed me to create custom sensors for real-time monitoring of battery percentage, load percentage, and system status. I also set up automation to notify me via SMS if the UPS switches to battery mode or if there’s a critical issue.
One thing I found particularly useful was the ability to remotely monitor and control the UPS through the Home Assistant dashboard. It gives me peace of mind knowing that my critical devices are protected, even when I’m not at home.
If you’re looking for an affordable and reliable UPS solution, I highly recommend the Salicru SPS SOHO+. The integration with Home Assistant is seamless, and the documentation is comprehensive. You can find my detailed setup guide on GitHub: Salicru SPS SOHO+ Integration.
Happy automating!
