Home Assistant 2026.5: RF 433, centralized maintenance, and new cards, the innovations that change everything

The May 2026 update of Home Assistant focuses primarily on user experience, daily maintenance, and smart automations. The result: a system that is more enjoyable to use on a daily basis, easier to maintain, but also much more powerful for those who like to push their smart home installations to the limit.

There are some very visible new features, such as the new maintenance dashboard or the Shortcut card. But the real gems are sometimes more discreet: new automation logics, support for RF 433 MHz, new local integrations… The Home Assistant community will clearly have plenty to enjoy this month.

Developers are also continuing their major project that began several months ago: making Home Assistant more accessible without sacrificing the power that makes it successful. And in this version, it’s immediately noticeable.

A new maintenance dashboard that is finally useful

This is probably one of the most important new features in this version. Home Assistant introduces a true centralized maintenance dashboard.

Until now, tracking the general status of an installation often required navigating between multiple menus: backups, updates, offline devices, low batteries, ESPHome errors, integrations needing special attention… In short, it wasn’t catastrophic, but clearly not optimal.

With Home Assistant 2026.5, everything is grouped into a single dedicated interface.

The new dashboard displays in particular:

• unavailable devices
• orphaned entities
• low batteries
• backups to verify
• integrations requiring action
• available updates
• detected configuration issues

For a large smart home installation, this is extremely convenient. We finally get a real “system health” view.

In a house equipped with dozens of Zigbee sensors, Shelly modules, ESPHome, and a few exotic Wi-Fi devices, this kind of dashboard quickly becomes indispensable. A temperature sensor that stops responding, a CR2032 battery that starts to weaken, or a device that becomes inaccessible after a network outage immediately jumps to the eye.

The new Shortcut card simplifies dashboards

Another very visible new feature is the arrival of the Shortcut card.

This new card may seem simple at first glance, but it will quickly become essential in many Home Assistant dashboards.

It allows three types of actions:

• navigate to another view
• launch Assist
• trigger a specific action or service directly

It may sound trivial. In practice, it greatly simplifies the creation of clean and ergonomic interfaces.

Imagine, for example, a wall-mounted tablet with large shortcuts:

• “Night mode”
• “Turn everything off”
• “Open the gate”
• “Start the vacuum”
• “Cameras”
• “Living room music”

Each button can have its own color, icon, and behavior. No need to fiddle with multiple different cards to get something neat.

This is also great news for those creating simple interfaces for the family. How many Home Assistant installations become unusable for other occupants because the dashboards look like an Airbus cockpit? Here, we really gain in readability.

The Shortcut card can also directly launch Assist in listening mode. On a wall-mounted tablet or a touch screen, this opens the door to very natural voice interfaces.

Robot vacuums become much more pleasant to use

Robot vacuums also benefit from a significant evolution in Home Assistant 2026.5. And this time, it’s not just a few hidden technical entities in a menu: the whole user experience has been revamped.

The new “more info” panel for robot vacuums has been completely modernized. When you click on your robot from a dashboard, Home Assistant now displays a much more visual and lively interface, with an animated illustration that changes according to the state of the robot. During cleaning, the robot “comes to life,” visually returns to its base when recharging, remains still when docked, and even shows specific animations in case of error. It may seem gimmicky when said like that… but in practice, the interface immediately appears much more modern and pleasant to use on a daily basis.

Battery life is also prominently displayed in the window header for immediate visibility, while the main actions such as start, pause, or send the robot back to its station are now grouped into a much more coherent action bar. You can really feel that Home Assistant is increasingly focused on user experience, and not just the technical part.

But the big news is especially the integrated zoned cleaning directly in the interface. Many modern robots can already clean a specific room, but until now Home Assistant didn’t really provide a native and straightforward way to utilize this function. Now, robot rooms can be associated with Home Assistant “Areas.” The result: from the interface, it is now possible to launch a targeted cleaning of the living room, kitchen, or bedrooms in just a few clicks.

For example, imagine a very simple automation: after a meal, a “Clean kitchen” button appears on the wall-mounted tablet and directly triggers the robot to clean only that room. Or a scenario where the robot automatically cleans the entrance when everyone leaves the house. With this new native zone management, this type of use becomes much more natural to implement.

Advanced users will also appreciate another slightly more discreet new feature: vacuums created via the Template integration can now expose their own segments and clean_segment actions. In clear terms, even custom or DIY integrations can now take advantage of the new native zoned cleaning system.

And Home Assistant hasn’t stopped at vacuums: robotic lawnmowers benefit from exactly the same graphical overhaul. Same logic of animations based on state, same modern display, same organization of actions. A harmonization that makes the whole interface much more coherent.

Automations become much smarter

For several versions, Home Assistant has been working on “use-oriented” triggers rather than technical ones. Version 2026.5 takes this approach even further.

Instead of manipulating raw states or numerical values, automations can now use much more natural triggers.

For example:

• when a light turns on
• when the heating starts
• when a vacuum begins cleaning
• when a door remains open
• when a device becomes unavailable

This may seem trivial, but it greatly changes the readability of automations.

Previously, some rules quickly became unreadable with complex conditions based on specific states or attributes. Now, Home Assistant exposes business actions more comprehensible directly.

This is particularly useful for beginners… but also for advanced users with hundreds of automations.

Let’s take a concrete case. An automation for the bathroom can now be read almost like a sentence:

“When the heating switches to heating mode AND presence is detected for more than 5 minutes, automatically turn on the towel warmer.”

It’s much cleaner.

Version 2026.5 also introduces cross-domain triggers. Home Assistant is starting to better understand the “role” of a device rather than just its technical state.

This evolution is important for the future of the platform.

RF 433 MHz becomes a first-class citizen

Here’s a new feature that is likely to please tinkering enthusiasts and retrocompatibility fans.

After infrared support last month, Home Assistant now introduces true support for RF via ESPHome.

And here, the possibilities become enormous.

The 433 MHz frequency is still omnipresent in many devices:

• radio sockets
• roller shutters
• gate remote controls
• weather stations
• basic sensors
• bells
• Chacon or Dio equipment
• old automations

Until now, properly integrating these devices into Home Assistant often required external solutions that were more or less elegant.

With this development, small ESPHome modules compatible with RF can serve as “RF proxies,” similar to current Bluetooth Proxies.

For many older devices, this provides an opportunity to give them a smart second life instead of replacing everything. And that is quite clever.

Users of Somfy RTS shutters should keep a close eye on this in the coming months…

Serial ports also go over the network with ESPHome

Another very interesting new feature, especially for somewhat technical installations: Home Assistant 2026.5 now allows exposing a serial port over the network thanks to ESPHome.

Until now, a device in RS-232, an energy meter with a P1 port, or certain audio/video equipment often had to be physically connected to the machine hosting Home Assistant, sometimes with endless USB cables or rather messy setups. Now, an ESPHome module placed in the right spot can serve as a “serial proxy”: you connect the serial device to it, and then Home Assistant sees it remotely as if it were connected locally.

This is particularly convenient for reading an electricity meter in the panel, controlling a Denon amplifier via RS-232, connecting a projector, or integrating older equipment without replacing it.

Technically, Home Assistant has also revamped all its serial port management with a new driver named serialx, which is more modern, asynchronous, and capable of displaying local USB ports and ESPHome serial proxies side by side in the interface. A small enhancement on the surface, but a real boon for tinkerers, installers, and anyone who likes to keep reliable equipment in service rather than throw it away.

Many new integrations

Like every month, Home Assistant is further enriching its vast catalog of integrations. Version 2026.5 adds 12 new official integrations this time, with a strong emphasis on local, energy, RF, and technical equipment often overlooked by traditional home automation platforms.

Among the most interesting new features is the new Radio frequency integration, which now serves as the official base for all sub-GHz RF devices in Home Assistant. It notably allows the use of an ESPHome equipped with a CC1101 module or a Broadlink RM4 Pro as a native RF transmitter in Home Assistant. This layer then enables controlling devices such as the new integrations Honeywell String Lights or Novy Cooker Hood.

The Teleinfo integration should also be of great interest to French users. It allows for local retrieval of data from Linky meters via the TIC (Télé-Information Client) output. Instant consumption, tariff indexes, apparent power, or current can thus be fed directly into Home Assistant without an intermediate cloud. For all those working on their energy tracking or solar self-consumption, this is excellent news.

Also on the energy front, Home Assistant welcomes Victron GX, allowing the connection of Victron Energy equipment like the Cerbo GX, Venus GX, or Color Control GX via MQTT. Solar production, batteries, chargers, inverters, or charging stations thus become fully controllable and supervisable within Home Assistant. An integration that should quickly become essential for advanced users and installers.

The new EARN-E P1 Meter integration allows for real-time retrieval of smart meter data over the local network, while OMIE brings spot electricity prices for Spain and Portugal to automatically optimize consumption based on hourly rates.

Home Assistant 2026.5 also brings a highly anticipated integration for audio/video enthusiasts: Denon RS232. It allows the local control of certain Denon amplifiers via their RS232 serial port, with real-time status updates without cloud dependency or IP networking. And it’s exactly this integration that also serves as a perfect example for the new serial proxy feature via ESPHome introduced this month.

In terms of comfort and heating, the new Eurotronic Comet Blue integration adds support for several Bluetooth thermostats for radiators, while Fumis allows for the integration of WiRCU-compatible pellet stoves in Home Assistant. Ambient temperature, setpoint, start or stop of the stove then become controllable directly from home automation automations.

Users of connected ventilation will also appreciate the arrival of Duco, allowing local control of ventilation systems with CO₂ and humidity monitoring. A particularly interesting integration in modern highly insulated homes.

Other more specific integrations are also appearing, such as Kiosker for supervising web kiosks on iPad and iPhone, or Honeywell String Lights and Novy Cooker Hood, which directly leverage the new native RF layer of Home Assistant.

On the improvements side, this update is also very rich. MQTT gains new date and time entity types, Matter adds support for radon sensors, Sonos retrieves new advanced settings, Apple TV now supports remote keyboard input, while Shelly, Roborock, Tado, WLED, SwitchBot, and UniFi Access also receive numerous improvements.

Users of UniFi Protect (including me!) will particularly appreciate the arrival of true alarm management with sirens, control panels, and new long-range LoRa relays. Home Assistant is clearly continuing to become an extremely serious platform for advanced security installations.

Home Assistant dashboards continue to progress

Over the past year, dashboards have evolved greatly in Home Assistant.

And honestly, there was a need.

The old interfaces were powerful but sometimes frankly austere. Today, the platform is becoming much more modern visually.

Between the new Shortcut card, dedicated interfaces for robots, improvements in responsive design, and new visual components, you can feel that Home Assistant is now trying to appeal to “normal” users as well, not just geeks.

And that’s a great thing.

Because a connected home that is genuinely used daily must be pleasant to operate. Not just powerful.

An especially interesting update for advanced users

Even though this version clearly improves the experience for beginners, advanced users will also find it very interesting.

The RF 433 MHz, infrared proxies, new smart triggers, and local network integrations open up many possibilities.

A few very concrete examples:

• reusing old radio shutters in Home Assistant
• integrating an IR air conditioner without cloud
• simplifying complex dashboards
• monitoring the overall status of an installation automatically
• creating much more readable automations
• controlling audio equipment locally
• integrating professional UniFi access control

This kind of new features may not make as much noise as a new generative AI… but in real life, it is these that truly improve a home automation installation.

Should you install Home Assistant 2026.5?

Definitely yes.

This version is very balanced. It brings both:

• visual improvements
• useful maintenance tools
• smarter automations
• new hardware possibilities
• interesting local integrations

The new maintenance dashboard alone almost justifies the update for a large installation.

ESPHome users will also greatly appreciate the arrival of RF and infrared proxies, which open the door to many cost-effective projects.

And above all, Home Assistant continues to progress without losing its DNA: local, powerful, open, and ultra-flexible.

A decidedly reassuring direction for the future. As always, remember to back up beforehand. Then, it’s time for this great update! For those who want to test before migrating, the Home Assistant test environment I provide has been updated, so feel free to check it out, it’s made for that!
