Shelly joins Works with Home Assistant

We’re excited to welcome Shelly to the Works with Home Assistant program! Shelly is very well-established in both our ecosystem and the smart home world, so it’s great to formally certify a selection of their Z-Wave devices.

Their retrofit smart switches and relays are amazing for turning all sorts of dumb devices, like light fixtures or ceiling fans, into devices you can easily control in smart new ways. Also, being Works with certified means they have been thoroughly tested, ensuring they give the best possible experience with Home Assistant.

The variety of complex settings and functionality, like energy monitoring, makes them popular with our community doing advanced smart retrofits, like connecting an old garage door or motorized shutters. These are perfect for keeping non-smart devices out of the landfill and working for years to come.

From A to Z-Wave

Shelly, originally launched in Bulgaria in 2017, has been a mainstay in our community for some years. They became known initially for their WiFi smart switches and relays that could be easily used locally, but now offer a wide range of smart devices and ways to connect them. For this first round of Works with Home Assistant certified products, the focus is firmly on the Z-Wave lines.

 If you’re not familiar with Z-Wave, it’s a well-established low-powered wireless technology designed with the smart home in mind. It uses an entirely different bit of radio spectrum than WiFi, meaning it has less chance of experiencing interference. This spectrum makes it better at getting through thick walls and communicating over longer distances — with the recent Long Range iteration of the standard, they can communicate even further.

Given our focus on local control, items that work on Z-Wave are ideal if you want to avoid the cloud. Home Assistant will act as your Z-Wave controller using the Z-Wave JS add-on (another awesome Open Home Foundation project). So, all you need is a Z-Wave adapter to use alongside these devices. If you haven’t purchased one yet, you might want to wait before hitting that buy button 😉.

Shelly shares our focus on interoperability, with items using a variety of protocols, while being available worldwide. These items are also super helpful for the energy-conscious. They have low power consumption, power metering, and can easily blend in with your current home decor, as they sit in the wall behind your existing switches.

Mini? This thing is microscopic!

Getting Involved

We’ve been lucky enough to meet the Shelly team on several occasions, and they were kind enough to showcase how the Las Vegas Mob Museum uses Shelly and Home Assistant during our annual ‘State of the Open Home’ event. In May, they went one step further and hosted one of our Community Days in South Florida. It’s really exciting to see that partners who join the ‘Works with’ program don’t just see it as a badge to stick on a box, but a real chance to engage with, and contribute to, this amazing community.

"Many of our users already rely on Home Assistant to power their smart homes, and we’ve seen firsthand how important local control, privacy, and flexibility are to them. By joining the Works with Home Assistant program, we’re reinforcing our commitment to open, reliable smart home solutions. With the upcoming launch of our Shelly Wave Long Range devices—offering wireless coverage of up to 1 kilometer — we’re pushing the boundaries of what smart home technology can do. Combined with Home Assistant’s powerful platform, this will be a market-leading solution, capable of covering use cases no other ecosystem today can reach. Together, we’re building the future of smart homes: open, powerful, and ready for real-world demands."

Devices

In case you didn’t know, Works with Home Assistant differs from other certification programs as products are rigorously tested in-house to ensure they work seamlessly out of the box. Any company joining also commits to providing long-term support and firmware updates while being a positive force in the Home Assistant community. Works with Home Assistant is operated by the Open Home Foundation, and the support of Home Assistant Cloud subscribers funds this work.

What devices have been certified?

Whilst the Shelly Wave Pro 1PM sits in an electrical box, the remaining devices sit behind a standard plug, switch or device. This means they are a super cost-effective way to retrofit devices, which in turn reduces e-waste. The Minis are very small (duh), and so should fit in most tight places around the home, even with low-profile installations. The Shelly Wave 1PM Mini is the world’s smallest Z-Wave smart switch. In some areas of the world, you may need professional installation by a qualified electrician, so be sure to check your region’s regulations. If you’re a confident DIYer, Shelly has a lot of helpful guides on their site to walk you through installing it yourself.

The first of many waves

These devices are the first from Shelly to join the program, but certainly won’t be the last, as we look forward to many exciting developments with Z-Wave Long Range. Keep your eyes peeled for our upcoming hardware announcement that will work perfectly with our Z-Wave partners.

Thanks again for your support (by subscribing to Home Assistant Cloud and buying official hardware), which allows the Open Home Foundation to build these partnerships and certify new devices to join Works with Home Assistant.

FAQs

Q: If I have a device that is not listed under ‘Works with Home Assistant does this mean it’s not supported?

A: No! It just means that it hasn’t gone through a testing schedule with our team yet or doesn’t fit the requirements of the program. It might function well but be added to the testing schedule later down the road, or it might work under a different connectivity type that we don’t currently test under the program. It may also have a feature missing in Home Assistant that we’re working to add.

Q: Ok, so what’s the point of the Works with program?

A: It highlights the devices we know work well with Home Assistant and the brands that make a long-term commitment to keeping support for these devices going. The certification agreement specifies that the devices must work well within Home Assistant, operate locally without the need for cloud and will continue to do so long-term.

Q: How were these devices tested?

A: All devices in this list were tested using a standard HA Green Hub, a Z-Wave adapter and with our Z Wave integration. If you have another hub / adapter / integration that’s not a problem but we test against these as they are the most effective way for our team to certify within our ecosystem.

Q: Will you be adding more Shelly devices to the program?

A: Absolutely. Shelly has a huge number of product lines and will be expanding their Z-Wave Long Range list. We’re sure they’ll keep our testers busy with a steady stream of devices to add.

Great news! There are some very nice synergies between Shelly and Home Assistant and maybe they can leverage Home Assistant to save some of the effort they put into Shelly’s scripting language.

Well done to all for continuing to grow the Works With programme.

I’d welcome some mention of Shelly’s non-Z-Wave products, and ideally an indication of some kind of timeline for certification as well. Z-Wave products are not ideal in our part of the world due to a non-standard frequency; Zigbee/wifi/Thread devices are more standardised so easier for us to source.

I was very happy to read this announcement. Congratulations to both the Shelly and Home Assistant teams! This collaboration makes perfect sense and is a huge benefit to the community.

While it’s exciting to see the Z-Wave line get the official certification, I wanted to voice my strong support for including the WiFi portfolio in the future. Many of us have built our smart homes around WiFi for its simplicity and are now looking to integrate Matter devices without adding extra hubs.

I’m eagerly awaiting the day Shelly’s WiFi products join the “Works With Home Assistant” program. Keep up the excellent work!

Fun. I have been looking into Shelly items for a while. Just installed a Shelly PM Mini Gen3 to monitor the power usage of my QuietCool attic fan before I start in on hacking/swapping the controller. I’ve read people using a shelly 2P to handle the two speed fans.

Massive news. Congrats.

Nice news, I own several of Shelly’s Z-Wave devices and the physical form factor is great, however the firmware could need some tune ups so hoping to see OTA firmware updates soon.

But how about also certifiying Shelly’s Zigbee devices for Home Assistant’s ZHA integration as well? See the upstream device discussion here:

Hmm, I have a number of shelly zwave devices, in fact they are my only zwave devices, and they are unreliable trash. Shelly support promised firmware updates to fix bugs over a year ago, yet nothing (shelly wave plug uk) the smart plugs randomly reboot themselves (power cycling the attached device in the process.

The shelly wave shutters that control my blinds require me to turn the circuit off and on at the breaker once a week or so as they drop off the network.

It has really put me off zwave and is why I haven’t invested further.

What does the sentence " If you haven’t purchased one yet, you might want to wait before hitting that buy button " mean?

Open Home Foundation and Nabu Casa members have in recent months kept hinting that an upcoming official Home Assistent branded Z-Wave Controller USB adapter (based on Z-Wave 800 series radio chip and with an external antenna) will be announced soon, so suspect that a the release date for it that will probably be officially announced on the blog very soon, but if it will be available for purchase at the date of the annoucement is a different question. The last hint about that official Z-Wave Controller USB radio dongle was in the Zooz announcement a couple of weeks ago, see here:

Quote: ”Watch this space for a not-so-secret Home Assistant Z-Wave hardware announcement coming your way

So guess they mean that if you were considering buying a Z-Wave Controller USB adapter from a other manufacturer then maybe hold of that purchade until the announcement has been made so you know the release date. Though you will be able to migrate if you are already using Z-Wave JS with a different not-too-old Z-Wave Controller USB adapter that has new enough firmware.

FYI, they been hinted about this for what feels like two years but the fact that they are working on a prototype of a Z-Wave Controller USB radio adapter dongle that will have an external antenna was first made clear more than a year ago in the ”ZWave is not dead” blog post here → Z-Wave is not dead - Home Assistant

Anyway, Paulus has very strongly hinted verbaly several times duing the last few Home Assistent release party videos that their Z-Wave Controller adapter will be available ”soon” so one could guess that it will be in stock and available for sale when it is announced (as the Home Assistant Green and SkyConnect was).

I suspect that they are holding of on the release until their software matured for backup and restore for migrations, while also waiting for Z-Wave Long Range in Europe to be ratified.

There is also a new rumour now about additional new hardware because in the latest video Paulus also hinted that there will not only be a Z-Wave Controller USB radio dongle but there will maybe be another hardware announced as well then, so my guess there is that they will also announcing a optional matching ESPHome serial-to-USB network adapter that can allow users to convert the USB dongle into a network connected adapter which would enable you to place it anywhere on your local LAN (or maybe not anywhere if it is PoE powered and only uses Ethernet instead of WiFi. At least I think those are realistic guesses based on the related ”USB Host” and ”USB UART” features that was recently added to ESPHome → ESPHome 2025.6.0 - 18th June 2025 — ESPHome

PS: ZBT-1 and ZWA-2 are still terrible product names IMHO, as I think they should be called something like ”Home Assistant Zigbee or Thread USB radio adapter” and ”Home Assistant Z-Wave 800 USB radio adapter” or alternativly just call them by some color and version like their hub appiances (e.g. Home Assistant Purple USB radio dongle).

Thank you for the detailed explanation.

They now dropped another huge hint here → 📢 August 13th - Save the date!

For reference, sounds as if the current firmware of Shelly’s Zigbee devices does not yet support Zigbee OTA (Over-The-Air) updates which is probably needed for WWHA Zigbee device certification → Full support for Shelly devices? Does all of Shelly's Zigbee devices require support for custom Shelly clusters + Zigbee OTA and should all those new features be fully exposed in ZHA? · zigpy/zha · Discussion #470 · GitHub

Again, so far Shelly have only certified their Z-Wave devices and there is unfortunatly no mention if certification for Zigbee devices is also planned or not.

FYI, as I understand it, the agrement guidelines for that ”Works with Home Assistant” partner certification program stipulate that the company wanting to certify Zigbee devices for WWHA is more or less required to provide standard Zigbee OTA firmware updates nativly via Home Assistant’s built-in ZHA integration for certified Zigbee devices for standaized sustainability with support for local updates, and the devices themself also needs to have Zigbee CSA Certification as well.

Available to access firmware updates directly in Home Assistant

Ideally, all devices should be able to access over-the-air (OTA) firmware updates from within our system. If this isn’t possible, you must provide a way to alert users about firmware updates.
