Home Assistant’s March 2026 Update Enters Beta
Following a monthly release rhythm, Home Assistant unveils a new update on the first Wednesday of each month, with the preceding Wednesday introducing the beta version of upcoming features.
The latest iteration, March 2026’s update (version 2026.3), has entered beta, distinguished by a groundbreaking feature: wake word detection on mobile devices via the Home Assistant app, eliminating the necessity for Termux and a Wyoming Satellite.
I have routinely installed the beta versions on my setup, typically allowing a short period for initial issues to be resolved.
Having utilized 2026.3 for a day, the highlight is unmistakable: Android users finally receive on-device wake word detection directly through the Companion app.
While this release also includes enhancements to the energy dashboard and a novel method for managing robotic vacuums, the enthusiasm surrounding wake word support is palpable.
It is pertinent to note that this remains a beta version. Waiting for the comprehensive release is prudent, as certain features may not transition to the final version due to potential bugs or operational discrepancies.
Wake Word Detection Arrives on Android
Local, On-Device, and Experimental
Historically, wake word detection in Home Assistant required dedicated hardware solutions, such as ESPHome-powered voice satellites or the Atom Echo, demanding unique configurations for voice control.
With the advent of 2026.3, this paradigm shifts; the Home Assistant Companion app on Android can now recognize wake words directly through the smartphone.
The implementation harnesses microWakeWord technology, paralleling that used in ESPHome devices. Currently, three wake words are available—”Okay Nabu,” “Hey Jarvis,” and “Hey Mycroft.”
Notably, all processing transpires locally on the device, ensuring that no data is transmitted to external servers for wake word recognition. This contrasts with openWakeWord, which relies on continuous audio streaming to the Home Assistant server.
Nonetheless, it is vital to acknowledge that this feature is markedly experimental and will impact battery consumption significantly.
The constant activation of the device microphone cannot be achieved without the efficiencies offered by dedicated hardware, a fact Nabu Casa readily recognizes.
Fortunately, users can program automations that customize wake word detection activation, such as enabling it when connected to home WiFi or disabling it upon departure.
For those with older smartphones idle in a dock, this could serve as a practical means to repurpose the device as a voice-enabled apparatus without incurring additional hardware costs.
In scenarios where multiple devices hear the wake word concurrently, they will respond intelligently. The device processing the wake word most swiftly will take precedence, thereby mitigating chaos when several devices are poised to react.
The enhancements to voice control extend beyond wake word detection. Users can now instruct their voice assistant to remove items from a to-do list, complementing the previously available “complete item” command.
While seemingly minor, this functionality alleviates significant frustration for those reliant on Home Assistant’s to-do lists for grocery management. The addition may not entice fervent demonstrations, but it undeniably enhances the everyday user experience.
Energy Dashboard Receives Enhancements
Robot Vacuums Communicate Fluently with Home Assistant
Recent iterations of Home Assistant’s dashboards have shown remarkable progress, particularly the energy dashboard, which has evolved into one of its most compelling features, though it occasionally struggles with more complex home setups.
Version 2026.3 introduces several significant refinements, including new tile cards that offer instantaneous readings of power, gas, and water consumption, with water now exhibiting its own Sankey visualization—a feature previously exclusive to electricity flows.
The configuration interface has also undergone a transformation. The former monolithic setup screen has been streamlined into three separate tabs for electricity, gas, and water, simplifying independent management of each utility.
Additionally, the renaming of the “Energy” tab to “Electricity” is a practical adjustment that fosters immediate comprehension. Tooltips in the graphs now reflect daily usage, proving beneficial for analyzing consumption patterns throughout the week.
For robot vacuum users, this update is particularly notable. The newly introduced “vacuum.clean_area” command allows users to direct their vacuum cleaner to specific Home Assistant-defined areas, eliminating the need to navigate through manufacturer-app-specific identifiers.
Supported from launch by Matter, Ecovacs, and Roborock integrations, automated repair alerts will alert users if there are any changes to the vacuum’s segment layout.
This enhancement fosters a sense of actual control over the device, rather than merely acting as an intermediary for vendor commands. Future voice support for area-specific cleaning commands, such as “clean the kitchen,” is also anticipated.
Automations Become More Intuitive
Seamless Continuity Amid Errors—No YAML Needed
Home Assistant’s automation editor has witnessed substantial enhancements in recent months, continuing with a noteworthy feature that bridges the gap between YAML-based and UI-based automations. A new “Continue on error” toggle is now available in the user interface.
Anyone who has experienced an automation sequence derailing due to a single action’s error will recognize the value of this feature.
Users can enable the “Continue on error” option for specific actions, permitting the automation to progress despite individual hiccups.
Transitioning this functionality from YAML to the user interface considerably increases discoverability for those less experienced with automation intricacies.
The mechanism is straightforward. A visual cue will identify any action set to proceed after an error, allowing users to quickly ascertain which steps are designed to withstand faults. While this feature may not be particularly flashy, it addresses a significant gap in the automation process.
Innovative and Enhanced Integrations
17 New Integrations with Numerous Upgrades
As always, the community remains industrious. The latest release introduces 17 new integrations, encompassing Liebherr for appliance monitoring, MTA New York City Transit for real-time transit information, Trane Local for HVAC management, and OneDrive for Business for cloud storage solutions.
Additionally, InfluxDB, Ness Alarm, and Splunk can now be configured through the user interface, eliminating the previous dependence on YAML.
Improvements to existing integrations are noteworthy as well. Matter has expanded functionality to support carbon monoxide and TVOC sensors; Reolink now accommodates PTZ diagonal rotation; SmartThings facilitates dual-cavity Samsung ovens; and Roborock can manage Zeo washing machines.
Other integrations, including SwitchBot, UniFi Protect, SleepIQ, Proxmox VE, and Portainer, have also received valuable updates.
As this is a beta release, standard precautions apply. Users are encouraged to back up their systems prior to updating and to anticipate potential imperfections.
While the features discussed are likely to feature in the stable release, certainty only comes with the official launch.
Overall, this beta is remarkably substantive, and the introduction of Android wake word detection renders it one of the most exciting monthly releases in recent memory.
