With the Home Assistant 2026.5 Beta, the Open Home Foundation has released one of its most comprehensive updates in recent memory. This release not only brings numerous improvements to dashboards and automations, but also opens Home Assistant up more to traditional wireless technology and older hardware generations for the first time. Existing devices will remain compatible, while the user interface is modernized and configuration is simplified.

Home Assistant discovers classic wireless technology

Perhaps the most important new feature of Home Assistant 2026.5 is the introduction of native support for Radio Frequency (RF). While Home Assistant has previously focused primarily on modern smart home standards such as... Zigbee, Z-Wave or Matter Since this has been implemented, traditional two-way radios can now be integrated much more easily. These include, among others:

• 433 MHz radio-controlled sockets
• older roller shutter controls
• Wireless remote controls
• older smart home components

Initially, the implementation will take place via two integrations:

• ESPHome in combination with suitable radio modules for the frequency ranges 315, 433, 868 and 915 MHz. For DIY projects, Home Assistant recommends, among other things, the well-known CC1101 radio module*.
• As finished Complete solution will also be the Broadlink RM4 Pro* supported, which already has an integrated 433 MHz transmitter and receiver.

What's interesting is the project's strategic direction: After the introduction of infrared support in Release 2026.4 Support for legacy hardware is now being specifically implemented. According to the beta notes, this should also pave the way for future hardware products from Nabu Casa* prepare.

Serial-over-IP with ESPHome

Another technically exciting innovation is the support for serial interfaces over the network via ESPHome. This allows serial devices to be connected decentrally and, for example, linked to Home Assistant via Wi-Fi. Previously, many serial devices required direct wired connections. The new solution allows for much more flexible integration of such devices into existing installations. This should be particularly interesting for heating controls or smart meters, which are often installed in basements.

New dashboard for maintenance

Home Assistant 2026.5 also introduces a new integrated Maintenance dashboard. This dashboard automatically detects devices relevant for maintenance and displays their status centrally.

The current focus is primarily on the battery levels of sensors that don't have a fixed power supply. Especially in larger systems with many different sensors, battery management has often been fragmented and required individual dashboards to monitor the status. With the new Maintenance dashboard, Home Assistant significantly reduces this effort.

Dashboard security now includes live activity view

The security dashboard has also been enhanced with new features. A new integrated activity sidebar displays security events in real time.

This includes, for example, window and door sensors, motion detectors, door locks, and camera movements. As a result, Home Assistant is increasingly evolving from a pure automation system into a fully-fledged security solution.

New map for quick access

One of the most noticeable new features is the new map, which can display various quick access options. It allows navigation to dashboards, areas, or device views, triggering actions, launching the voice assistant, or linking to external URLs.

This eliminates the need for many previously required specific and complex solutions. Especially on mobile dashboards, the new map provides significantly faster and clearer user interfaces.

Conclusion Home Assistant 2026.5 Beta

Home Assistant 2026.5 Beta clearly demonstrates the direction the project is heading. It features more modern dashboards and improved support for existing hardware. In particular, the new RF support and Serial-over-IP capabilities are likely to have a significant long-term impact, as they will allow older generations of devices to be integrated much more easily into modern smart home systems.

Those already testing the beta should still expect minor bugs and unfinished features until the final release.
