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 Novu?

Novu makes its workflows controllable by AI agents and by code, not just dashboards.

Novu's recent arc moves notification workflows out of a single editing surface. November introduced Contexts for multi-tenant scoping, January shipped Subscriptions plus a React Subscription component, April let any step run in Custom Code mode with CLI publishing, and the Novu MCP Server went GA in late April with 20+ tools covering subscribers, triggering, cancellation, and integrations. Slack chat is in private beta.

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.

2.1

Novu makes its workflows controllable by AI agents and by code, not just dashboards.

◆ Current state

Novu's recent arc moves notification workflows out of a single editing surface. November introduced Contexts for multi-tenant scoping, January shipped Subscriptions plus a React Subscription component, April let any step run in Custom Code mode with CLI publishing, and the Novu MCP Server went GA in late April with 20+ tools covering subscribers, triggering, cancellation, and integrations. Slack chat is in private beta.

◆ Where it's heading

Novu is positioning as a notification platform an AI agent can drive end-to-end and a developer can wire from code, with the dashboard becoming optional. The MCP Server GA codifies that pitch publicly. Expect more tools exposed over MCP and continued depth on tenant scoping, since multi-tenant SaaS is the main buyer.

◆ Prediction

The next directional move likely formalizes agent-built workflows as first-class artifacts with versioning and approval, so AI-authored notifications can survive review. Slack and other chat integrations should leave beta and join the standard provider list.
