Home Assistant 2026.5 Adds Native RF Support for Legacy Devices

Key Takeaways

• Home Assistant 2026.5 adds native RF transmitter integration for legacy devices
• Users can now control garage doors, ceiling fans, blinds, and RF outlets through the platform
• The update mirrors last release's infrared support, using existing ESPHome transmitters

Home Assistant 2026.5 shipped this week with native radio frequency support. The feature opens a door that community plugins have been prying at for years: connecting devices that use RF signals instead of Wi-Fi, Bluetooth, or Matter.

Garage door openers, ceiling fans, motorized blinds, doorbells, and RF-controlled power outlets can now join your Home Assistant setup through official integrations. No more hunting for community workarounds or hoping someone maintains a third-party plugin.

How the RF Integration Works

Home Assistant isn't adding its own RF transmitter. Instead, it uses transmitters you already have in your setup, like an ESPHome device with a sub-GHz transmitter attached.

“The new Radio frequency integration follows the exact same pattern as last release's infrared platform. It's an entity type that represents an RF transmitter, like an ESPHome-powered device with a sub-GHz transmitter attached. You don't set it up directly. Instead, other integrations use it to send RF commands on your behalf, and you simply pick which transmitter they should use.”

— Franck Nijhof, Home Assistant lead engineer

This pattern mirrors the infrared support added in Home Assistant 2026.4. That update let users add TVs, air conditioners, and other IR devices to their setups. The approach keeps the complexity low: you pick a transmitter, point an integration at it, and Home Assistant handles the rest.

Supported Devices at Launch

Two device-specific integrations ship with this update: Honeywell String Lights and Novy cooker hoods.

• Honeywell String Lights: on/off control via RF commands, plus full Home Assistant automation support
• Novy cooker hood: control the light and extractor fan

Two integrations sounds modest, but the pattern matters more than the launch list. The RF platform is now a standard entity type. Any developer can build integrations against it. Community support will follow.

Why RF Support Matters

Home Assistant's core value proposition is local control. Your devices stay connected without cloud dependencies. They work when your internet goes down. Your data stays on your network.

But that promise has always had a gap. Plenty of useful devices, especially older or simpler ones, use radio frequency instead of smart protocols. A ceiling fan remote. A garage door opener. Window blinds you bought five years ago. These devices worked fine, but they sat outside your Home Assistant setup.

Community plugins filled some of these gaps, but with the usual caveats: inconsistent maintenance, varying quality, and the overhead of managing unofficial integrations. Native support changes the calculus. It's official, documented, and maintained by the core team.

What You Need to Get Started

The RF integration requires a compatible transmitter. ESPHome devices with sub-GHz transmitters are the primary option mentioned in the release notes. If you're already running ESPHome for other purposes, adding RF capability is straightforward. If not, you'll need to set up a transmitter device first.

Once your transmitter is in place, device integrations will let you select it as the RF sender. The actual RF commands get handled by the device-specific integration.

The Bigger Picture

Home Assistant has been on a connectivity expansion push. The infrared platform in 2026.4 and now RF support in 2026.5 show a clear strategy: make the platform work with whatever devices people actually own, not just the newest smart home gear.

This matters for adoption. Most homes aren't fully smart. They have a mix of new devices, old devices, and devices that work fine but use protocols from 2015. Home Assistant's path to becoming a true central hub runs through supporting all of them.

Frequently Asked Questions

What devices can I control with Home Assistant RF support?

Garage door openers, ceiling fans, motorized blinds, doorbells, and RF-controlled power outlets. At launch, official integrations exist for Honeywell String Lights and Novy cooker hoods, with more expected from the community.

Do I need special hardware for Home Assistant RF?

Yes. You need an RF transmitter, such as an ESPHome device with a sub-GHz transmitter. Home Assistant uses your existing transmitter to send RF commands.

How is native RF different from community RF plugins?

Native RF support is maintained by the Home Assistant core team, documented officially, and follows a standard integration pattern. Community plugins vary in quality and maintenance.

Does Home Assistant RF work without internet?

Yes. Home Assistant runs locally on your network. RF commands go through your local transmitter without cloud dependencies.
