HS1SA-E Updates: remote test and siren features

Hi Community Users,

We’ve heard many of you requesting Remote Test, Remote Mute, and Siren features that were previously only available on the newer HS1SA-E Plus model. To best support our users and extend the life of your current hardware, we are releasing an optional firmware update for the original HS1SA-E.

If you would like to plug and play, please try to buy HS1SA-E Plus, this post is only for who already had HS1SA-E.

This update bridges the gap between models by enabling several highly requested features.

What’s New

Once updated, your HS1SA-E will support:

  1. Remote Test: Trigger a self-test via Home Assistant without needing physical access to the device.
  2. Remote Temporary Mute: Silence the alarm remotely during false triggers.
  3. Smoke Siren Activation: Manually trigger the siren for use in automations (e.g., as part of a home security system).
  4. Identify Device: Easily locate a specific sensor via visual/audible feedback.

Compatibility & Requirements

  • Manufacturing Date: This firmware is intended for units manufactured in 2022 or later.
  • Recommendation: For the best stability, we strongly recommend testing this on devices manufactured after 2024.
  • Battery Impact: Please note that enabling these remote features will increase battery consumption. While the device remains energy-efficient and should still last for years, the battery life will be shorter than the original “low-power” factory state.

Note: Please ensure you have a stable Zigbee/network connection before initiating the update to prevent any interruptions.

I noticed that, too. I will fix it with next release.

@leoXie has kindly sent me a version 15 firmware file. I normally use ZHA so was able to install it using the Home Assistant ZHA OTA update guide 2026 instructions. That being said the appropriate entity config hasn’t been added to ZHA yet so the new features won’t actually work after the upgrade.

If you use Z2M I can confirm they work perfectly.

Once that’s set up and Home Assistant is restarted, perform the following steps:

  1. Visit the alarm device page (Settings → Devices and services → Zigbee Home Automation → {Device name}).
  2. Click the firmware upgrade link in the Configuration section and start the upgrade process.
  3. Use a pin to press the recessed button on the alarm to wake it.
  4. The firmware upgrade should start shortly after the button press. This took about 90 minutes to complete.

I placed my alarm near the Zigbee coordinator during the upgrade. This probably isn’t necessary but I wanted to ensure a reliable upgrade.

I’ve also checked the state of it with Z2M and the new entities appear immediately, so for Z2M users this update is ready to go out of the box.
