The same ESPHome YAML could produce a different configuration depending on the computer that compiled it. Change #21678 by Jonathan Swoboda, merged into the development branch on 26 October 2026, fixes that for the !include_dir_* tags by loading files in name order. The fix is expected in ESPHome 2026.11, unless it is backported to a 2026.10.x patc
Two ESPHome changes merged over the weekend deal with climate devices that do not work in Celsius. The first, by Johan Henkens (jhenkens), reviewed by bdraco and merged on 25 October 2026, adds a unit_of_measurement option to the template climate and the template water heater and fixes how visual temperatures are converted on platforms that report
Adafruit has started selling the Metro ESP32-P4 Hydra (product ID 6536), a board in the Arduino Uno shape that pairs Espressif's ESP32-P4 application processor with an ESP32-C6 for wireless. CNX Software covered it on 26 October 2026. The price is $34.95, with a limit of two per customer.
A pulse reader on the electricity meter tells you how much the whole house uses. It does not tell you how much of that goes to the heat pump, the boiler, the workshop or the kitchen circuit. For that you need a meter on the circuit itself, and the Peacefair PZEM-004T V3 is a cheap way to get one: a small board that measures voltage, current, power,
Speech recognition on a microcontroller usually means a wake word or a fixed list of commands. esp32-pie-asr, an open-source project by Boumedine Billal, goes further: it transcribes open-vocabulary English speech live on Espressif's ESP32-P4, with no cloud service and no separate neural accelerator. Version 1.0 was released on GitHub on 25 October
ESPHome can already build firmware for nRF52840 boards, but updating them over Bluetooth required the MCUboot bootloader and the zephyr_mcumgr component. Many popular boards, such as the nice!nano, the Adafruit ItsyBitsy nRF52840 and the Feather nRF52840, come with the Adafruit bootloader instead, so they still had to be flashed over USB. A pull re
Two ESP32 features merged earlier this month for ESPHome 2026.11 came with limits. The WISP mode turns a board into a small Wi-Fi repeater with NAT, but it rejected captive_portal. The modem component connects an ESP32 to the internet through a cellular modem, but its first version left out signal-strength sensors. Three pull requests merged into t
