# LocalTuya can stop loading after a Home Assistant update: check its issue tracker before updating

> LocalTuya is a custom integration and has repeatedly broken on Home Assistant releases (e.g. 2025.1, 2025.5, 2025.12, 2026.3). Fixes often land in the repository before a release. Back up before updating and check the tracker first.

## Symptom

After updating Home Assistant, all LocalTuya devices are unavailable and the integration shows "not loaded" or "config flow could not be loaded". Nothing changed on the devices.

## Why

LocalTuya is a **custom integration**. It uses Home Assistant internals that Home Assistant deprecates and removes over time. Its GitHub tracker shows this repeatedly:

| Home Assistant | Reported LocalTuya problem |
|---|---|
| 2025.1 | issues when updating (widely reacted issue) |
| 2025.5 | failed to load: `'HomeAssistant' object has no attribute 'helpers'` from a `hass.helpers.service.async_register_admin_service()` call |
| 2025.12 | "Config flow could not be loaded" |
| 2026.3 | color temperature control broken (mired → kelvin migration) |

For 2025.5, a fix was committed (9f4405a) and many users confirmed it worked, but it reached HACS as an update only afterwards, so users either patched the file by hand or waited.

## What to do

1. **Before each Home Assistant update**, open the LocalTuya issue tracker and look for issues mentioning the new version.
2. **Create a backup before updating.** Home Assistant can do this automatically before updates, which lets you restore the previous state if the integration no longer loads.
3. If it breaks: check the tracker for a confirmed fix or release. Hand-patching `custom_components/localtuya` works, but it is overwritten by the next update, and Python indentation errors are a common mistake.
4. **Consider the alternatives** described in the Tuya-in-Home-Assistant comparison (official Tuya integration, Tuya Local). Choose based on your devices and on how quickly each project follows Home Assistant releases.

## Claims

- After Home Assistant Core 2025.5.0, LocalTuya failed to load with AttributeError: 'HomeAssistant' object has no attribute 'helpers', because it called hass.helpers.service.async_register_admin_service(). (unverified)
- The LocalTuya issue tracker has open issues about breakage with Home Assistant 2025.1, 2025.12 (config flow could not be loaded) and 2026.3 (color temperature control). (unverified)
- The LocalTuya load failure on Home Assistant 2025.5 was fixed by commit 9f4405a in the LocalTuya repository, confirmed by many users, before an update was available in HACS. (unverified)
