# Tuya in Home Assistant: official integration vs Tuya Local vs LocalTuya

> The official Tuya integration is cloud push with QR login via the Smart Life app. Tuya Local and LocalTuya control devices over the LAN with local keys; Tuya Local supports protocol 3.5 and ships device definitions, LocalTuya covers protocols 3.1 to 3.4.

| | Official Tuya integration | Tuya Local | LocalTuya |
|---|---|---|---|
| Connection | Tuya cloud (**cloud push**) | local LAN | local LAN |
| Works without internet | no | yes | yes |
| Setup | QR / user code login with the Smart Life or Tuya Smart app | device ID, IP, local key, protocol; optional cloud-assisted setup via your Tuya account | device ID and local key; optional Tuya IoT cloud credentials to fetch keys |
| Protocol versions | n/a | 3.1–3.5 and 3.22 | 3.1–3.4 |
| How devices are described | Tuya's official SDK | ready-made device configuration files (large library) | you map data points to entities in the UI |
| Notes | lock and remote platforms not supported; the SDK doesn't expose everything the app can do | still lets devices report to the Tuya cloud | community custom integration |

Tuya Local and LocalTuya are installed as custom integrations (typically through HACS); the official one is built in.

## Recommendation

- **Fastest start, few devices, internet is reliable:** official integration.
- **Local, and your device is in Tuya Local's device list:** Tuya Local. The ready-made definition saves you mapping data points, and it handles protocol 3.5.
- **Local, device not in any list, you're comfortable mapping DPs yourself:** LocalTuya or a new Tuya Local device file (contribute it back).

## Gotchas for all local options

- A device accepts only one local connection: don't run two local integrations (or a TinyTuya script) against the same device.
- Re-pairing a device in the app changes its local key; update the integration afterwards.
- Reserve device IPs in your router.

## Claims

- LocalTuya supports Tuya protocols 3.1 to 3.4 and can optionally use Tuya IoT cloud API credentials to retrieve and update local keys. (unverified)
- The official Home Assistant Tuya integration supports all Home Assistant platforms except the lock and remote platforms. (unverified)
- Tuya Local supports Tuya protocol versions 3.1, 3.2, 3.3, 3.4, 3.5 and 3.22 and identifies devices through device configuration files. (unverified)
