# Tuya Zigbee devices: same model ID, different datapoints

> Many Tuya Zigbee devices use the manufacturer-specific manuSpecificTuya cluster with Tuya datapoints (DPs) instead of standard Zigbee clusters, and share model IDs across different hardware. Support is per manufacturerName (e.g. _TZE200_...).

## Symptom

A cheap Zigbee sensor, thermostat valve or curtain motor pairs fine but shows as unsupported, exposes the wrong features, or a device that "is supported" behaves differently from the one in the documentation, although the label and model name are identical.

## Why

- Many Tuya devices don't use standard Zigbee clusters for their functions. They tunnel everything through the manufacturer-specific **`manuSpecificTuya`** cluster as **datapoints (DPs)**: a DP ID, a data type and a value, one per function.
- **Many Tuya devices share the same modelID** but use different datapoints. The distinguishing field is the **manufacturerName**, e.g. `_TZE200_d0yu2xgi`. White-label products under different brands can be the same device, and one brand's "model" can hide several different devices.

So support is per *manufacturerName + modelID fingerprint*, not per product name.

## What to do

1. **Before buying**, look up the exact manufacturerName (from reviews, forums or the stack's device list), not just the product name.
2. **After pairing**, read the device's manufacturerName and modelID in Zigbee2MQTT or ZHA and compare with the supported-devices entry.
3. **Unsupported**:
   - Zigbee2MQTT: write an **external converter** (JavaScript in the `external_converters` folder next to `configuration.yaml`) that maps DPs to exposed features; once it works, contribute it upstream so it becomes built-in.
   - ZHA: support comes through **ZHA Device Handlers ("quirks")**, device-specific Python scripts.
4. Expect **firmware variants**: the same fingerprint can change behavior after a vendor firmware change.

Tuya devices are often good value, but budget time for this when the exact variant isn't listed yet.

## Claims

- Zigbee2MQTT external converters are JavaScript files placed in an external_converters folder next to configuration.yaml and work like built-in converters. (unverified)
- Many Tuya devices share the same Zigbee modelID but use different datapoints, so Zigbee2MQTT fingerprints them by manufacturerName (for example _TZE200_d0yu2xgi). (unverified)
- Many Tuya Zigbee devices use a custom manuSpecificTuya cluster and communicate through Tuya datapoints (DP IDs) rather than standard Zigbee clusters. (unverified)
