What is ESPHome?

ESPHome 2026.9.0 ships template climate component, OTA encryption with API key, and ESP-NOW for ESP32-P4

ESPHome 2026.9.0 is out, capping a beta cycle that added a template climate component (a long-requested flexible HVAC control primitive), OTA encryption keyed to the device's API key (hardening the update path), and ESP-NOW over hosted shim for the ESP32-P4. The beta cycle also included a systematic RAM allocation safety pass across the codebase — heap exhaustion now returns an error instead of panicking. Monthly releases continue landing at a consistent pace.

What is Obsidian?

Obsidian's feed has gone quiet: version pointers up top, the bundled CLI the last real move.

The four most recent entries are pointers, not release notes — each says only that the build includes everything up to Obsidian Desktop v1.13.1 through v1.13.4, with no description of what actually changed. The last substantive work visible in this window is from March, when the installer started bundling a dedicated CLI binary instead of invoking the Electron executable, cutting terminal round-trip time and adding shell autocompletion for Obsidian commands. Everything published since is content-free rollup text.

ESPHome 2026.9.0 ships template climate component, OTA encryption with API key, and ESP-NOW for ESP32-P4

◆ Current state

ESPHome 2026.9.0 is out, capping a beta cycle that added a template climate component (a long-requested flexible HVAC control primitive), OTA encryption keyed to the device's API key (hardening the update path), and ESP-NOW over hosted shim for the ESP32-P4. The beta cycle also included a systematic RAM allocation safety pass across the codebase — heap exhaustion now returns an error instead of panicking. Monthly releases continue landing at a consistent pace.

◆ Where it's heading

ESPHome is expanding in two directions simultaneously: broader hardware support (ESP32-P4, BK72xx BLE, new platform components) and more robust runtime behavior (RAMAllocator pattern, use-after-free fixes, better BLE-WiFi coexistence). The template climate component is the most user-visible addition — it brings custom HVAC logic into ESPHome's declarative model, reducing the need for external Home Assistant automations. Audio stack (i2s, resampler, mixer) reliability is also a consistent focus.

◆ Prediction

The 2026.10.0 cycle will likely continue the RAMAllocator pattern across remaining allocating code paths and add more ESP32-P4-specific features. Audio (voice assistants, speakers) will stay a top area given the ongoing i2s reliability work.

Obsidian's feed has gone quiet: version pointers up top, the bundled CLI the last real move.

◆ Current state

The four most recent entries are pointers, not release notes — each says only that the build includes everything up to Obsidian Desktop v1.13.1 through v1.13.4, with no description of what actually changed. The last substantive work visible in this window is from March, when the installer started bundling a dedicated CLI binary instead of invoking the Electron executable, cutting terminal round-trip time and adding shell autocompletion for Obsidian commands. Everything published since is content-free rollup text.

◆ Where it's heading

Treat the CLI work as the signal and the rollups as noise: a first-class terminal entry point is what lets external tools and scripts drive a vault, which is the difference between a local-first notes app and a substrate other software can build on. The follow-up entries — a macOS path check and a hidden socket dotfile — show the CLI being hardened for real cross-platform use rather than shipped and abandoned. Meanwhile this feed itself has stopped carrying detail, deferring to the desktop release notes it points at.

◆ Prediction

The visible thread is CLI and TUI ergonomics, so continued work on that surface is the safest read; nothing in these entries supports a confident call beyond it. What is genuinely unclear is whether this feed resumes describing releases or stays a pointer to the desktop changelog.
