⚠️ Major update: ESPHome 2026.6.0 replaces the legacy dashboard with the new ESPHome Device Builder. If you have ESP8266 devices on WPA-only/TKIP Wi-Fi, set wifi.min_auth_mode: WPA before updating. Also review the upstream upgrade checklist if you use DSMR electricity_switch_position, Nextion dump_device_info, custom components, Home Assistant time zones, or advanced lambdas.
The new Device Builder adds a visual component and automation builder, a CodeMirror YAML editor, device labels and areas, firmware job history, cross-config search, settings, and a command palette.
This release also improves Wi-Fi and Ethernet memory handling when disabled at boot, speeds up LVGL config validation, modernizes the audio stack, expands DLMS meter support, and adds new IMU, USB-serial, audio DAC, pressure sensor, display, and tooling features.
