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 Lima?

Lima keeps widening which machines it can run on, and run.

Lima runs Linux virtual machines for container workloads, and its 2.x line has been a steady expansion of the host and guest matrix. macOS and FreeBSD guests arrived at 2.1.0, Windows Server 2025 and Windows 11 guests followed through 2.2.0, and 2.3.0-beta.0 adds an experimental HCS driver for Windows hosts along with further Windows guest work. Each platform addition lands marked experimental first, and much of the surrounding work is CLI and template maintenance.

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.

Lima keeps widening which machines it can run on, and run.

◆ Current state

Lima runs Linux virtual machines for container workloads, and its 2.x line has been a steady expansion of the host and guest matrix. macOS and FreeBSD guests arrived at 2.1.0, Windows Server 2025 and Windows 11 guests followed through 2.2.0, and 2.3.0-beta.0 adds an experimental HCS driver for Windows hosts along with further Windows guest work. Each platform addition lands marked experimental first, and much of the surrounding work is CLI and template maintenance.

◆ Where it's heading

The project is converging on a single tool that runs any guest on any host, and it is doing so from both ends: guest support and host drivers advance in alternating releases. Windows is the current focus on both sides, having moved from an unsupported host default to qemu and now to a native HCS driver option. The LFX mentee contributions behind much of this suggest the platform matrix expands as contributor capacity allows rather than on a roadmap.

◆ Prediction

The HCS driver should follow the same path the other platform additions took, moving from experimental to a supported or default option on Windows hosts once the guest work stabilises around it.
