Heiman Dev here: Working on HA Cloud Integration for SubG Smoke Alarms

[leoXie]

Hey everyone,

As both a Home Assistant enthusiast and a developer at Heiman, I’m excited to share a quick update with you all regarding some new integration work we’re doing.

We know some of you are using our Sub-1GHz (SubG) Smoke Alarms and Gateways (the ones often found on Amazon). We’re currently working on an official Cloud Integration to bring these devices into Home Assistant so you can finally get those alerts and sensor states directly in your dashboards.

Why SubG wireless?

1. Extended Whole-Home Coverage: High-penetration radio waves easily reach across multiple floors, providing reliable connectivity even in a 3-story building.
2. Seamless Native Interconnection: Built-in support allows your Smoke, CO, and Heat alarms to talk to each other instantly—if one alarm sounds, they all sound. No hub required.
3. Ultra-Reliable Connectivity: Unlike Wi-Fi, Sub-GHz operates on a quiet, interference-free frequency. It stays connected even if your internet goes down.
   
   
   
   
   

We are currently in the development phase and I would like know if there any experimental users wish to test it before released.

We’re really excited to bring better support to our existing hardware alongside our newer Matter/Thread products. If you’re interested in being an early tester, let me know in the comments or shoot me a DM!

The integration code has open sourced:

GitHub - Leo2442926161/heiman_home: Heiman Home

How to use it?

1. install the Samba and start your samba in your Home Assistant:
   

   

2. Access to the folder of your HA by typing the IP address of \192.168.20.192.
   

   

3. create custom_components a folder in config directory.
   

   

4. download the source from Heiman Repo: GitHub - Leo2442926161/heiman_home: Heiman Home · GitHub
   

   

5. copy it to directory \config\custom_components and unzip it, change the folder name to heiman_home
   

   

6. Congrats, you are all set, restart you Home Assitant.

7. after reboot, navigate to Integration page and Add Heiman Home integration
   

   

8. install Heiman Home
   

   
   
   
   

9. Click the redirection and login it with Heiman Home account.
   

   

10. grant the permissions with Home Assistant
    

    

11. Authentication Successful
    

    

12. Back to your HA and sync Heiman devices to Home Assistant
    

    
    
    
    
    
    
    

13. Heiman Home Integration has successfully added.
    

    

14. Overview of smoke alarm page.
    

    

Cheers!

This sounds useful, especially for getting alerts into dashboards. I’ve got a couple of those SubG alarms running, so I’d be interested in trying the integration once there are setup steps available.

Hi Mcloom, the guide has updated, could you have a try and let me know if there is any questions.

Remote mute! Cheers loudly!

One of the progressive vendors addressing a growing market segment for hobbyists that will attract more sales.

Will there be API documentation released, and a local network ONLY version available that does not rely on the Internet other than the initial on-boarding usual for Matter devices?

[leoXie]

Thanks IOT7712,
In the feature, yes, so someone can contributes the code as well. we will try to implement the local network, too, so it doesn’t replies on internet.
