Home Assistant 2026.5 unlocks forgotten RF devices without cloud hacks – Automated Home

There is a good chance your garage door opener, motorized blinds, or holiday string lights are still living their best analog life, completely cut off from the smart home you have spent years building.

These are devices that speak radio frequency and only radio frequency, and for a long time, that meant choosing between complicated workarounds or leaving them behind entirely.

Home Assistant 2026.5 was released on May 6, 2026. The May 8 release was patch version 2026.5.1. It changes that with native RF support that pulls these forgotten devices into a modern local smart home with no cloud dependency required.

How does native RF support actually work?

Home Assistant 2026.5 introduces a new radio frequency entity platform that treats RF communication the same way the platform already handles infrared. The approach uses a middleware layer that separates the hardware from the devices being controlled, making the system flexible and scalable.

Compatible transmitters connect to Home Assistant over a local network and register as RF transmitter entities. Consumer integrations for specific devices then pull encoded commands from an external RF-protocols library and route them through whichever transmitter matches the required frequency.

One RF proxy can control devices across the whole home

One ESPHome proxy placed anywhere in the house can handle commands for blinds, fans, lights, and sockets simultaneously.

The platform launches with support for 433 MHz on-off keying, the modulation type used across a wide range of consumer RF products. ESPHome CC1101 supports an operating frequency range of 300 MHz to 928 MHz. Broadlink RM pro/RM4 pro RF entities support 433.05–434.79 MHz and 314.95–315.25 MHz.

What hardware do you need?

The hardware requirements are intentionally low-cost. The Broadlink RM4 Pro, which retails for around $30, is a supported transmitter that works out of the box after setup in the Home Assistant interface.

It is worth noting that only the RM4 Pro model in the RM4 series includes RF support, so buyers should verify the model before purchasing. For those who prefer a DIY path, an ESPHome-based device with a CC1101 module runs around $10 and delivers the same core functionality.

Setup requires adding a simple YAML code block to define the frequency and pins. And setup for commercial hubs takes roughly 15 minutes using Home Assistant’s guided, code-free UI flows.

Which devices are supported at launch?

Home Assistant 2026.5 launches with Honeywell String Lights and Novy Cooker Hood integrations using the new RF platform.

Honeywell string lights gain on and off control through RF commands, and Novy cooker hoods support both light and fan control. The RF platform is designed to grow with more transmitter integrations, device integrations, and protocols over time.

Adding a new ESPHome RF proxy to a different part of the house immediately extends control to all RF devices without requiring a new configuration for each one.

How does this compare to older RF workarounds?

The contrast with previous approaches is significant. Legacy tools like RFLink and Pilight, the latter of which has been fully disabled in 2026.5, required complex YAML-based setups and frequent maintenance.

Cloud bridges introduced latency and external server dependencies that made them unsuitable for reliable long-term automation. The new RF platform mirrors the infrared system introduced in Home Assistant 2026.4.

Both follow the same architecture, where a single entity type abstracts the transmitter hardware and consumer integrations handle device-specific encoding.

RF fills the gap that Matter cannot reach

This consistency makes the RF system far easier to maintain and extend than anything that existed before. RF also fills a specific gap that modern standards leave open. Zigbee and Z-Wave offer reliable ecosystems but require dedicated hubs and do not support legacy RF devices.

Matter and Thread focus on newer certified hardware and have no pathway for sub-gigahertz RF compatibility. A $10 CC1101 module connected to an ESPHome board can unlock an entire category of devices that $50 Matter hubs simply cannot reach.

Little-known fact: Home Assistant documentation currently lists 433 MHz and 315 MHz bands for RM pro/RM4 pro RF entities.

What else comes in the 2026.5 update?

RF support shares the release with several other meaningful additions. ESPHome now supports serial proxy functionality, allowing RS-232 serial devices to be connected over a network.

This opens integration for older AV receivers, smart meters, and industrial sensors that would otherwise require physical proximity to a Home Assistant server. The new Maintenance dashboard focuses on battery entities, grouping them by area and highlighting low batteries.

For installations with dozens of Zigbee sensors and ESPHome devices, having immediate visibility into low batteries or offline hardware saves significant time. A new security activity log also tracks events from door sensors, motion detectors, locks, and cameras in real time.

Why the local-first approach matters?

Home Assistant’s RF implementation reinforces what makes the platform distinct from consumer smart home systems.

Every command is transmitted locally with no internet connection required. No manufacturer server can shut down, no subscription can expire, and no cloud outage can leave devices unresponsive.

With more than 2 million active installations, Home Assistant’s move to support RF at a platform level has an immediate practical impact. Many legacy remotes and low-cost household devices use proprietary RF.

Nabu Casa, the commercial partner behind Home Assistant Cloud, is also working on a forthcoming device codenamed Project Blast that will combine infrared and RF capabilities in a single polished package. The 2026.5 RF platform is part of the technical foundation that makes that product possible.

TL;DR

• Home Assistant 2026.5 introduces native radio frequency support for legacy sub-gigahertz devices like motorized blinds, garage doors, and RF outlets, all running fully locally with no cloud dependency.
• Compatible transmitter hardware is inexpensive, with ESPHome-based CC1101 modules available for around $10 and the Broadlink RM4 Pro offering a ready-made option for around $30.
• The new RF platform uses the same architectural pattern as last month’s infrared update, so one transmitter placed anywhere in the home can control multiple RF devices simultaneously.
• Launch integrations include Honeywell string lights and Novy cooker hoods, with community development already underway for garage door protocols and additional device categories.
• Home Assistant’s RF system fills a gap that Zigbee, Z-Wave, and Matter cannot address, offering a local and extremely low-cost path to automating devices these standards were never designed to support.
• The new Maintenance dashboard focuses on battery entities, grouping them by area and highlighting low batteries.
