[Deprecation Warning] localtuya uses deprecated hass.helpers.service - will break in Home Assistant Core 2026.1

[LeonardSEO]

Issue Summary

While running Home Assistant Core 2025.3.3 on Home Assistant OS 14.2 (Raspberry Pi 5), I encountered the following deprecation warning in the system logs regarding localtuya:

WARNING (MainThread) [homeassistant.helpers.frame] Detected that custom integration 'localtuya' accesses hass.helpers.service, which should not be used. This will stop working in Home Assistant 2025.5, please create a bug report or fix.

Additionally, there are multiple warnings about deprecated constants used by localtuya that will be removed in Home Assistant Core 2026.1, causing inevitable breaking changes if not addressed.

Details

localtuya is currently accessing:

hass.helpers.service.async_register_admin_service()

This is explicitly flagged by Home Assistant core developers for removal.

Other deprecated constants used (examples from logs):

STATE_CLEANING, STATE_DOCKED, STATE_ERROR, STATE_IDLE, STATE_PAUSED, STATE_RETURNING

These will also be removed in Home Assistant Core 2026.1.

Request

Could you please:

• Refactor localtuya to stop using hass.helpers.service.async_register_admin_service()

• Ensure compatibility with upcoming Home Assistant versions

I am available to help test any potential fixes.
