ZemiSmart ZMS-206 / ZMS-208 Display Switch – ZHA Quirk Update Notice

We would like to share an update regarding our ZMS-206 and ZMS-208 display switches.

Due to continuous feature improvements and firmware updates, the device identifiers (Device ID / Signature) of these models may change over time. As a result, some users may experience compatibility issues when integrating the devices with ZHA (Zigbee Home Automation) in Home Assistant.

Background

The ZMS-206 and ZMS-208 display switches receive continuous feature and firmware improvements.
As a result, device signatures may vary across different production batches.
In some cases, this may cause:

  • Incorrect or incomplete device recognition in ZHA
  • Missing or limited entity functions
  • Inconsistent behavior across firmware versions

To address this, we have updated our ZHA custom quirk

What’s New

This updated ZHA quirk provides unified support for both ZemiSmart ZMS-206 and ZMS-208 display switches. It improves compatibility with newly introduced device signatures and ensures consistent behavior across different production batches and firmware versions.

Key improvements include:

  • Unified compatibility for ZMS-206 and ZMS-208 SKUs
  • Enhanced support for new and updated device IDs

Installation (Recommended via GitHub)

You can install the updated quirk directly from our GitHub repository:

  • Download the latest quirk files from the repository

  • Copy them into the folder above

  • Restart Home Assistant

  • Re-pair the device (recommended)

Notes

  • If your device is not correctly recognized, it is likely due to a new or updated device signature.
  • Installing the latest quirk will usually resolve recognition or functionality issues.
  • Existing users are encouraged to update to ensure continued compatibility.

Feedback & Testing

We welcome users to test this update and share feedback, including device model (ZMS-206 / ZMS-208), firmware version (if available), and any issues or unexpected behavior. We also welcome collaboration with experienced Home Assistant users, developers, and technical enthusiasts interested in testing, contributing improvements, or co-developing features—please feel free to contact us.
