Home Assistant 2026.7: automations that speak your language, and a from-scratch Matter rewrite

On July 1, the Home Assistant project released version 2026.7 under the title "2026.7: Automations that speak your language," calling it its biggest automation upgrade yet. Alongside it comes a from-scratch rewrite of the Matter integration, replacing its old Python-based Matter Server with a new one built on matter.js, the TypeScript implementation of the standard. Both changes directly affect how millions of local smart-home installations manage their devices.

Home Assistant is the open-source home automation platform developed by the nonprofit Open Home Foundation, and it has established itself as the leading local-first alternative to closed smart-home ecosystems like Google Home, Amazon Alexa, and Apple Home. Its adoption of Matter — the industry-wide interoperability standard backed jointly by Apple, Google, Amazon, Samsung and others — matters because Matter is meant to let devices from different brands work together regardless of ecosystem. Version 2026.7 doubles down on that bet with a renewed technical foundation.

Weekly context

The centerpiece of the announcement is the graduation of intent-based automation triggers out of opt-in beta: instead of wiring low-level conditions, users can now describe what should happen in a more natural-language-style way, and this becomes the default automation experience for everyone. In parallel, the new Matter Server v9.0 — first previewed on June 23 in the post "The Matter upgrade you've been waiting for" after roughly four months of public beta testing — replaces the old Python-based implementation with one built on matter.js, reaching full compliance with the Matter 1.5.1 specification. On July 9, as an early visible effect of this ecosystem push, IoTorero became the first manufacturer to bring ESPHome-ready pre-flashed smart plugs and relays into the official "Works with Home Assistant" certification program.

What changed

  • Intent-based automations become default: automation triggers based on intent, previously opt-in beta, are now the standard automation experience for all Home Assistant users.
  • Matter Server v9.0 on matter.js: the old Python-based implementation is replaced by a from-scratch rewrite on matter.js, with full Matter 1.5.1 spec compliance.
  • New Matter device categories: Matter 1.5.1 compliance unlocks support for cameras, doorbells, and closures (blinds, curtains, and garage doors).
  • Redesigned networking for reliability: the networking stack was completely redesigned, making device discovery, connections, and reconnections more reliable, with faster startup and recovery and fewer bugs overall.
  • New diagnostic tooling: a graphical Thread network visualization tool with separate "Thread" and "WiFi" tabs, plus new diagnostic sensors (Reboot Count, Uptime, Boot Reason) and binary sensors (Hardware Faults, Radio Faults, Network Faults) for Matter devices.

Impact for development and product teams

For people running Home Assistant instances, the matter.js-based Matter Server rewrite should translate into fewer dropped connections and more predictable startups, which matters especially in installations with dozens of Matter and Thread devices. Owners of Matter, Thread, and Zigbee devices gain real visibility into the health of their networks through the new diagnostic tabs, making it easier to catch hardware or radio faults before they turn into day-to-day problems. For developers building ESPHome integrations or community add-ons, intent-based triggers becoming the default means revisiting how integrations expose entities and services, since they now need to be legible from a more declarative automation layer too. The overhauled ZHA device management UI and the new dedicated infrared and RF panels further widen the surface developers can build on.

Practical recommendations

  1. Before updating to 2026.7, take a full backup of your Home Assistant configuration, including the Matter store and Zigbee/ZHA databases.
  2. Review the new intent-based automation editor and evaluate whether existing automations would benefit from migrating to intent triggers, without rushing to rewrite everything at once.
  3. Check whether your Matter devices — especially cameras, doorbells, or closures — benefit from the newly supported categories under Matter 1.5.1 before considering the update complete.
  4. Use the new Thread and WiFi diagnostic tabs to review mesh network health after updating, paying attention to the new hardware, radio, and network fault sensors.
  5. If buying new smart plugs or relays, consider IoTorero's ESPHome pre-flashed devices certified under "Works with Home Assistant," which require no manual flashing before they integrate.

What to watch next

  • The support timeline for Matter 1.6 and how it will integrate with the new matter.js-based Matter Server.
  • The pace of new community integrations beyond the 10 added in this release.
  • Whether third-party voice assistants adopt a similar approach to intent-based automation triggers.
  • Growth of the "Works with Home Assistant" certification program following IoTorero's entry as the first manufacturer with pre-flashed ESPHome devices.
  • How the matter.js rewrite performs in large installations running hundreds of Matter and Thread devices in production.

Conclusion: Home Assistant 2026.7 is not a minor update: it changes, at the root, how an automation is defined and what technology underpins integration with the industry's most important interoperability standard. For anyone running local smart-home installations, the combination of more readable automations and a more reliable Matter layer should be noticeable day to day — provided the update is approached with the usual caution: backup first, review after.
