Home Assistant 2026.3: New Features and Updates Explained

Home Assistant 2026.3 shipped in early March 2026. Its title, A clean sweep, is a fair summary: the release prioritizes community contributions, integrations and polish over one big headline feature. The new features are explained here by summarizing the official 2026.3 release notes, so every claim below comes from there, not from a personal upgrade log.

Bottom line: Home Assistant 2026.3 adds vacuum area cleaning, energy dashboard badges and a water chart, a visual Continue on error option in the automation editor, experimental on-device wake word detection in the Android app, and a move to Python 3.14. Take a full backup first, then skim the breaking changes: color temperature in mireds on lights, the Snapcast group entities and Tado mobile device tracking are among the things that changed.

What Does Vacuum Area Cleaning Do?

The headline feature is the one the title points at. You can now map the segments of a robot vacuum to Home Assistant areas through the entity settings (the section is called Map vacuum segments to areas), which lets you ask for the kitchen instead of a map segment through the vacuum clean area action. A repair issue appears if the vacuum's segment layout changes later. Matter, Ecovacs and Roborock vacuums are supported at launch. The release notes describe it as a foundation for future voice assistant integration.

This is a neat example of why a platform layer above the hardware matters. A vacuum that speaks Matter or has a maintained integration becomes just another object in an area, alongside lights and covers. A cloud-only robot without such an integration stays outside it.

What Changed in the Energy Dashboard?

The energy dashboard gets the most visible polish of the release:

• Real-time badges in the Now view show power consumption, gas flow rate and water flow rate at a glance
• A new Sankey chart shows how water usage is distributed
• The Energy tab is renamed Electricity, with separate tabs for Electricity, Gas and Water
• Tooltips now include the day of the week

None of this changes what the dashboard measures. It changes how quickly you can read it, which matters because an energy view people can't parse at a glance usually goes unused.

What Is New in the Automation Editor?

The automation editor makes one useful option visual: Continue on error. It used to be YAML-only. Now you can switch it on from the action menu, so an automation keeps going when one action fails. The release notes give notification chains as the obvious use. If one notification service is down, the remaining messages should still go out.

That is a small change, but it removes a reason to drop into YAML for ordinary automations.

How Does the Android Wake Word Work?

The Home Assistant Companion app for Android gains experimental on-device wake word detection, built on microWakeWord. Three wake words are available: Okay Nabu, Hey Jarvis and Hey Mycroft. Detection runs locally on the phone, with no audio sent to the cloud for the wake word itself. The notes warn that continuous microphone use noticeably affects battery life, and suggest automations that start and stop detection depending on context.

It's marked experimental, so expect rough edges, and judge it by how it behaves on your own phone.

Which Integrations Improved?

Seventeen new integrations arrived, including OneDrive for Business and Powerfox Local at platinum quality, plus Ghost, Liebherr, MTA New York City Transit and Trane Local. Among the improvements to existing ones:

• Matter: carbon monoxide alarm and TVOC sensor support
• Reolink: five diagonal PTZ buttons and real-time patrol status, which is relevant to anyone with a pan-tilt model such as the Reolink E330 indoor camera in my own house
• SmartThings: dual-cavity oven support and dishwasher controls
• Roborock: a complete Zeo washing machine integration
• UniFi Protect: PTZ preset actions and patrol select entities
• SwitchBot: keypad passwords and a curtain slow mode
• KNX: UI-based number configuration and periodic state re-sending

Nine integrations reached platinum on the quality scale, which is a decent signal of long-term maintenance.

What Changed for Backups and Containers?

Two items in the notes matter more for how you run Home Assistant than for what you see on a dashboard. A new IDrive e2 integration lets you send backups to S3-compatible cloud storage, and the OneDrive for Business integration covers Microsoft 365 users. Both give you an off-site copy without building your own upload script, which is the part of backup advice most people skip.

On the container side, the notes say the images are now compressed with zstd instead of gzip, and that this requires Docker 23.0.0 or newer. Anyone running Home Assistant Container on an older Docker host should check that version before pulling the update. Home Assistant OS and Supervised installs handle this on their own.

What Else Changed?

The Settings pages for Matter, Z-Wave, Zigbee and Bluetooth were reorganized for clarity, and release 2026.9 later added a Matter network map. Assist can now remove to-do items by voice. The statistics graph card editor offers a Year period, the security dashboard shows window-type covers, and the sections view supports footer cards. Under the hood, Home Assistant moves to Python 3.14, which the notes credit with faster interpreter execution, quicker startup and better memory use. That happens automatically on officially supported installs.

What Are the Breaking Changes in 2026.3?

This is the part to read before you press update. The notes list these backward-incompatible changes:

• Lights: the color_temp parameter (mireds) is removed; use color_temp_kelvin instead
• LIFX: the color_temp parameter for pulse effects is deprecated
• BSB-Lan: the water heater mode on becomes performance
• Snapcast: group media player entities and the grouping actions are removed
• Tado: mobile device tracking is removed
• Template fans: state handling changed, so errors now show as unavailable instead of off
• Z-Wave: fan percentages were corrected, which can change the exact values reported

If you have automations, scripts or blueprints that set light color temperature in mireds, those are the first thing to search for in your configuration. Four bug-fix patch releases, 2026.3.1 (March 6) to 2026.3.4 (March 24), followed with fixes for Portainer, SmartThings, Miele, Z-Wave covers and other integrations, so a few days of waiting is often rewarded.

How Do You Upgrade to Home Assistant 2026.3 Safely?

Before upgrading, take these steps:

• Create a full backup through Settings, then System, then Backups
• Read the breaking changes above against your own integrations and automations
• Check that your custom integrations (HACS) have compatible updates available
• Test the upgrade on a non-production instance if you run critical automations

After upgrading, check the integrations you rely on most, then look at the log for new warnings. If you're new to Home Assistant, a stable release like this is a reasonable place to start, and the setup guide linked under Related Articles walks through the first steps.

What Does Home Assistant 2026.3 Get Right, and Who Should Wait?

It's a release that rewards people who actually use the platform: the energy badges, the Continue on error option and the Reolink and UniFi PTZ improvements are all small things that save a click every day. It doesn't contain a feature that changes how you use Home Assistant, and that is fine. Not every release has to be an event.

Who should wait a few days? Anyone with a large set of custom integrations, template fans or light automations written in mireds. The patch releases fixed several integrations within the first weeks, so a cautious schedule is cheap. Anyone on a fresh install with mostly built-in integrations has little to lose by updating right away, as long as the backup exists first.

Keep in mind that 2026.3 is no longer the newest release. As of October 2026 the current one is 2026.10, which swaps the map for a sharper OpenStreetMap-based vector version and adds one-click AI connection through the Model Context Protocol. If you're deciding whether to update today, read the notes for the release you'd actually land on rather than this one.
