As part of our ongoing product development, we continuously improve the **ZMS-206** and **ZMS-208** display switches through feature enhancements and firmware updates.

Because of these updates, some newly manufactured devices may use different **Zigbee device signatures (Device IDs)** than earlier versions. In certain cases, this can affect how the switches are recognized by **Home Assistant’s ZHA (Zigbee Home Automation)** integration.

To provide a better user experience, we have released an updated **ZHA custom quirk** with broader device support and improved compatibility.

## Why Was This Update Necessary?

The **ZMS-206** and **ZMS-208** are continuously evolving products, and firmware improvements are released regularly.

As a result, device signatures may vary between different production batches.

Some users may experience the following issues when adding the switch to Home Assistant through ZHA:

- The device is not recognized correctly
- Some entities are missing
- Certain functions are unavailable
- Different firmware versions behave differently

The updated quirk was created to solve these compatibility issues and provide a more consistent experience across all supported devices.

* * *

## What’s New in This Release?

### Unified Support for Both Models

The latest version combines support for both:

- ZMS-206
- ZMS-208

### Expanded Device Signature Support

We’ve added compatibility for newly introduced device signatures and updated firmware versions.

### Better Compatibility Across Different Production Batches

The new quirk helps ensure more consistent behavior, regardless of when the device was manufactured.

## Recommended Installation Method: GitHub

The easiest way to install the latest version is through our official GitHub repository.

### 1. Open Your Home Assistant Configuration Directory

Navigate to:

```auto
/config/custom_zha_quirks/

```

### 2. Download the Latest Files

Download the newest quirk files from our GitHub repository.

### 3. Copy the Files

Copy all files into the following directory:

```auto
/ config / custom_zha_quirks /

```

### 4. Restart Home Assistant

### 5. Re-Pair the Device (Recommended)

Although not always required, we recommend removing and re-adding the device after updating the quirk.

## Troubleshooting

If your switch isn’t recognized correctly, please check the following:

- Are you using the latest version of the quirk?
- Have you restarted Home Assistant?
- Have you re-paired the device?

In most cases, updating to the latest quirk will resolve recognition and functionality issues.

## We’d Love Your Feedback

If you test the updated quirk, we’d appreciate your feedback.

Please include:

- Device model (ZMS-206 or ZMS-208)
- Firmware version (if available)
- Home Assistant version
- Zigbee coordinator model
- Any issues or unexpected behavior you encounter

We’re also happy to collaborate with **Home Assistant users, developers, and smart home enthusiasts** who are interested in testing, contributing code, or helping us improve future integrations.
