Heiman joins Works with Home Assistant

Blog
1

After an amazing 2025 that saw 12 new Works with Home Assistant partners join the program, it’s now time to say “Hei” to the first partner joining us this year: Heiman.

Founded back in 2005, Heiman specialize in smart home security devices, and are bringing an impressive selection of safety-focused sensors and alarms to the program: including the first Matter carbon monoxide alarms to be certified, along with smoke alarms designed for international markets.

Keep it local, keep it safe

If you’re new to the Works with Home Assistant program, it’s designed to help you identify devices that work brilliantly with Home Assistant, and support the Open Home Foundation’s principles of privacy, choice, and sustainability.

These values all pivot around local control, something that’s essential when it comes to home safety. Your smoke and CO alarms need to work when you need them most, regardless of your internet connection or cloud service status (though if you want to check in on your devices while away from home, Home Assistant Cloud provides secure remote access, and your subscription helps fund this very program, among other things!).

Our in-house team has thoroughly tested Heiman’s devices to ensure they meet this key requirement, and we’re happy to report they did! But Heiman has gone further still by using the Matter open connectivity standard…

Why this matters

Matter was launched to be a unifying connectivity type with interoperability at its heart. Instead of being locked into one company’s ecosystem, Matter devices work across Home Assistant, as well as other platforms like Google Home.

Heiman’s Matter devices work over Thread, which adds another layer of benefits. Thread is a low-power wireless mesh network protocol, meaning each device can act as a “relay point”, extending network reach throughout your home. This is ideal for battery-powered sensors like Heiman’s that need to be energy efficient while maintaining reliable communication.

So why does all this matter for safety devices specifically? Well firstly, it’s important to know these smart devices will still work as “dumb” ones, so there’s always a failsafe if you decide to rebuild your Thread network, or start making tweaks. If your sensors integrate locally, it means you can automate basic checks, such as reminders to test an alarm once a month, or notifications of hardware faults. If you want to go even further, your smoke alarm could trigger emergency lighting, your CO detector could shut off your gas fireplace, or your leak sensor could close water valves, all without sending your private data through a third-party server. And this is just the sort of complete, interoperable ecosystem Heiman aims to provide.

"Our core goal has always been to enable every family to enjoy a safe and intelligent living experience. Home Assistant, as a world-leading open source smart home platform, has an open and inclusive ecological philosophy and strong compatibility with multi-brand and multi-protocol devices, which are highly consistent with the direction of our product research and development. We deeply understand that only by integrating into an open ecosystem can we break down device barriers and provide users with a truly seamless whole-house smart solution."

- Leo Xie, Software Engineer Manager at Heiman

Working with the community

Heiman is showing they’re true to these ambitions. Beyond getting certified, they’re planning to take an active role in the Home Assistant community by participating in discussions, listening to real-world feedback, and continuously optimizing their products based on what users actually need. They’re also sharing their technical expertise in smart home security, collaborating with developers to explore innovative safety scenarios that benefit everyone.

Devices

Heiman’s commitment to openness and community is also reflected in the devices we’ve certified, which also meet strict safety regulations across the US, Europe, Asia and beyond. Before Heiman joined, we had one Zigbee smoke alarm in the program. Now there are Matter options for multiple regions, plus the first certified carbon monoxide alarms: more choice, more coverage.

What devices have been certified?

Also worth noting: Heiman’s global presence allows them to deliver quality devices at prices that won’t break the bank. Safety sensors and alarms shouldn’t be a luxury, and Heiman’s approach means they don’t have to be.

No more guessing games!

Accessible pricing is just one way Heiman expands choice for users. We’ve found they also deliver on the other core principles behind the Works with Home Assistant program: local control protects privacy, and open standards ensure sustainability. And that’s the whole point of our certification process: to make it easier for you to spot manufacturers who genuinely commit to these values, taking the guesswork out of building your open home. For full details of all Works with Home Assistant partners, check out our certified device list.

Welcome to the program, Heiman, we’re excited to see what the community builds with these devices!

Frequently asked questions

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

No! It just means that it hasn’t gone through a testing schedule with our team, or doesn’t fit the requirements of the program. It might function perfectly well but be added to the testing schedule in the future.

OK, so what’s the point of the Works with program?

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 brands must continue to support the devices in the program.

How were these devices tested?

All devices in this list were tested using a standard Home Assistant Green Hub with the Home Assistant Connect ZBT-2 as the Thread Border Router and with our certified Matter integration.

Will you be adding more Heiman devices to the program?

Why not! We’re thrilled to foster a close relationship with the team at Heiman to work together on any upcoming releases or add in further products that are not yet listed here. We are also chatting with them about some exciting future plans.

A list of supported devices with links to their specific pages on the Heiman site would have been a valuable addition to this long press release.

The piece asks “What devices have been certified?” and never answers the question.

No more guessing games! Go on, tell us the actual details.

This seems to be an issue with the forum version of the post since the list is in the blog post:

This is great news! I actually bought one of their Matter enabled smoke detectors purely off their involvement with the community and it seems to be working very well for me. Not had an actual fire though!

This is probably a good discussion point - with such connected devices, what kinds of automations would you put in place for something like a fire alarm?

So far I’ve got:

  • Send a notification to my phone
  • Turn all the lights red
  • Play some kind of warning/sound on the smart speakers around my home

Anything else?

Don’t turn your lights red. Make it easy for yourself or first responders to see in case there is smoke in the rooms. Turn them all on white at full brightness instead.

That’s a great point. I didn’t mention in my post that the reason I have this smoke alarm is for my Garden office - the issue I was trying to solve was getting alerted when I’m not in the office (where I might not even hear the alarm). Solid point on the lights though, them going full bright should be enough of a sign something isn’t right.

Lots of manufacturers also make smart sirens which you can link up to an automation, so if the original is far away you also have a closer one. Especially if your smart speakers aren’t local.

I like the reddot smoke and CO alarms. I hope the HA support is as good with Zigbee as with Matter - I have a good mesh with zigbee devices built over the last three years, and don’t care to replace things with Matter till the zigbee things die.

Hopefully by the time my Nest Protects hit EOL, these guys will have hard-wired versions. I don’t care if the batteries can last the life of the device (claimed and rarely achieved), I’m DONE with batteries. I’ve spent quite a bit having power run to all the right places to stay on hard wired for the rest of my life, and I won’t go back! lol

I have several of the Heiman HS1SA-E Zigbee smoke alarm detectors which work great with the native ZHA (using ZBT-2 adapter as Zigbee Coordinator).

Only wish that they also made a mains-powered smoke detector model as well with a built-in rechargable battery for power backup.

For reference, I also have several Shelly Plus Smoke Alarm (which btw are by Heiman too) over WiFi which are terrible because they are battery-operated only.

Do the hard wired devices have some form of battery backup? In case the electricity shuts off just before the fire (short circuit will do that…).
Not criticizing, just curious about your setup.

Power consumption of Matter over Thead is lower than MoW (Matter over wifi), but indeed, mains-powered device is more solid If you’ve got wires in the wall. We will have mains-powered smoke alarms.

Nice to see another addition to the certification program! Just this week I looked into Thread/Matter capable smoke and CO sensors. The Heiman gear turned up in my search as well.

I hope they worked on the quality and reliability of their firmware and radio connectivity though. I still have seven Zigbee-enabled smoke sensors from Heiman in my home. The Zigbee part is so bad, I never got it to work properly on my Zigbee network and HA. On the plus side at least the smoke detection is pretty reliable.

They do! Those horribly expensive AA lithium batteries at that. Thankfully they do seem to last the life of the device since they’re not actually used, and they came with them iirc.

Kinda glad they’re going the way of the Dodo and very glad that good alternatives are coming to market. What Google has done to Nest since acquiring them should be illegal.

I have five of Heiman smoke detectors as well and their connections work great in my setup (with ZBT-2 adapter as Zigbee Coordinator for ZHA), so issue you see is likley your setup. Highly recommend you read and try follow my best-practice guide for Zigbee here → Zigbee network optimization: a how-to guide for avoiding radio frequency interference + adding Zigbee Router devices (repeaters/extenders) to get a stable Zigbee network mesh with best possible range and coverage by fully utilizing Zigbee mesh networking
