ESPHome's device builder now compiles multiple devices simultaneously

ESPHome's new Device Builder public beta allows compiling multiple devices simultaneously, streamlining smart home management. This update introduces job queues for concurrent compilation, out-of-sync detection badges, and cross-config YAML search for easier debugging and fleet updates. The beta version, available in June 2026, also includes real-time schema hints and offloads compilation to faster hardware, significantly improving the user workflow for managing numerous devices.
