Since Proxmox doesn't surface SMART temperature data on its dashboard, a lightweight script on the host polls smartctl and serves drive temps as JSON over the local network. The ESP32 fetches this payload over Wi-Fi and displays it with threshold alerts. The project is functional but still needs a proper enclosure and could be improved by also monitoring the LSI HBA card temperature. ## Full article daily.dev links to this article rather than hosting it.
