What's new

Version 2026.9.0+Sep 17, 2026

ESPHome 2026.9.0 is a major monthly update with faster parallel build-tool setup, ESP8266 native-toolchain groundwork and RAM savings, Noise-encrypted OTA updates, six new components, and expanded LVGL, Modbus, Tuya, networking, and sensor support.

Review the upstream breaking changes before updating if your configs use Modbus Controller custom_command, register_count, force_new_range, or skip_updates; ESP32 custom eFuse MACs with Ethernet, Bluetooth, Thread, or Zigbee; custom lambdas or external components; or components with unsupported non-default UART settings such as mhz19, daly_bms, or teleinfo.

Previous ESPHome 2026.8.2 release notes:

ESPHome 2026.8.2 is another follow-up to the recent ESPHome 2026.8.0 major update. If you're updating from a pre-2026.8 version, review the upstream upgrade checklist before updating if your configs use explicit BLE tracker IDs (esp32_ble_id -> ble_hub_id), voc/nox sensor keys, Modbus controller/server options, RC522 I²C defaults, custom web server integrations, RP2 on-die temperature ADC, LED strip color-order keys, or interrupt-pin inverted/allow_other_uses settings. This point release updates the bundled ESPHome Device Builder, fixes ESP-IDF reconfiguration after component discovery, resolves one_wire reset busy-waiting, improves ESP32 HTTP request watchdog behavior, and fixes LVGL select triggers, JC3636518V2 MIPI SPI dimensions, and ESP8266 mDNS update handling when the radio cannot transmit.

Version 2026.8.0+Aug 21, 2026

ESPHome 2026.8.0 is a major monthly update with an upstream upgrade checklist. Before updating, review the checklist if your configs use explicit BLE tracker IDs (esp32_ble_id -> ble_hub_id), voc/nox sensor keys, Modbus controller/server options, RC522 I²C defaults, custom web server integrations, RP2 on-die temperature ADC, LED strip color-order keys, or interrupt-pin inverted/allow_other_uses settings. This release adds a platform-neutral BLE layer with BLE tracking/proxy support across more chips including Raspberry Pi Pico W, BK72xx, and LN882H; improves build speed and ESP-IDF toolchain size; adds multi-interface Ethernet/Wi-Fi support, the new modbus_client component, multi-key OTA signature verification, runtime wake word management, Device Builder startup/upload/config-migration improvements, and fixes ESP32 BLE scan reliability, ESP8266 encrypted API/OTA stalls, crash reporting, and many components.
