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 rsyslog?

The syslog daemon on every Linux box now collects Kubernetes logs itself

rsyslog's August scheduled-stable snapshot adds imkubernetes, an input module that tails pod and container logs directly, handles CRI and Docker json-file records, merges partial CRI lines, and enriches from the Kubernetes API. It lands alongside a segmented disk-assisted queue engine that becomes the default for new stores, a CloudWatch Logs output module, and generic per-action rate limiting in drop or pace mode.

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.

The syslog daemon on every Linux box now collects Kubernetes logs itself

◆ Current state

rsyslog's August scheduled-stable snapshot adds imkubernetes, an input module that tails pod and container logs directly, handles CRI and Docker json-file records, merges partial CRI lines, and enriches from the Kubernetes API. It lands alongside a segmented disk-assisted queue engine that becomes the default for new stores, a CloudWatch Logs output module, and generic per-action rate limiting in drop or pace mode.

◆ Where it's heading

Three consecutive snapshots have pushed rsyslog out of its role as a local relay and toward being a full pipeline component: YAML config and native OpenTelemetry protobuf in April, an Elastic Beats input in June, a Kubernetes-native input now. The queue rewrite and rate limiting point at the same target, since those are the properties an edge collector needs to survive backpressure rather than what a syslog relay needs.

◆ Prediction

Expect the next snapshot to harden imkubernetes against the operational cases the notes already hedge on, particularly ServiceAccount token refresh and API failover, and to push more deployments onto segmented queues by default.
