## Source excerpt

Home Assistant 2026.9! 🎉 I'll be honest: Modbus has never been the flashiest part of Home Assistant. It quietly powers solar inverters, heat pumps, and energy meters, but only if you're comfortable hand-writing your own register map in YAML, a real wall that's kept a huge category of devices out of reach. This release finally makes room on the bus: integrations that already know how a device talks over Modbus, sharing a single connection instead of fighting over it, so you simply pick your device in the UI like anything else in Home Assistant. It won't show up in a screenshot, but modernizing Modbus is hands-down my favorite change this release. 🔧 I'm also really looking forward to jumping on the new Cloud voice processing myself and putting it through its paces. We're a household with a non-English main language, and if you've ever run a private voice assistant in one, you know exactly how fast accents and background noise trip things up. This new speech-to-text engine specifically targets those pain points, so I'm very curious to see how it holds up against my own accent. 😉 And there's plenty more: active alerts and favorites for the Security dashboard, a shared Sources panel for History and Activity, Activity that finally explains why something changed, a brand new network map for Matter, charts you can now navigate by keyboard and sound, and 13 new integrations! 🚀 One more thing before you dive in: we're at IFA Berlin this weekend! It's one of the largest consumer electronics expos out there, running September 4 to 8, 2026, and the Open Home Foundation has its own booth in the Smart Home hall: Hall 1.2, stand 1.2-153. If you're around, come find us and say hi. 👋 Enjoy the release! ../Frenck Home Assistant Cloud Seeing through the Cloud Test the new voice processing Float in to be a Cloud subscriber Active alerts and favorites for the Security dashboard A new Sources pane for History and Activity From what changed to why it changed Insights into your Matter world
