Home Assistant kept wasting power on my home lab, and this tiny change fixed it
A user experienced high CPU usage and noise from their home lab running Home Assistant. The issue was traced to a DNS plug-in that caused constant connection attempts to Cloudflare's DNS servers. A simple command to disable fallback attempts resolved the problem, leading to a quieter and more efficient setup.
- ▪The user had been running Home Assistant in a VM on Proxmox for about a year without issues.
- ▪They noticed unusual CPU spikes and fan activity, initially suspecting other VMs as the cause.
- ▪The problem was linked to the hassio_dns plug-in, which caused excessive DNS requests when a custom server was used.
