+
+### Summary of changes
+
+The `homeassistant.helpers.service.verify_domain_control` helper function is deprecated,
+and has been replaced with `verify_domain_entity_control`.
+
+Since release `2025.1` (via core PR https://github.com/home-assistant/core/pull/133062),
+a reference to `HomeAssistant` is available as a property of the `ServiceCall` object,
+and it became redundant to pass `hass` object to `verify_domain_control`.
+
+To update your integration:
+1. Replace the decorator as shown in the first example below
+2. (Optional) Move the nested functions to be module-level as shown in the second example below
+3. Test the changes
+
+The old `verify_domain_control` function will be removed in Home Assistant 2026.7.
+
+
+### Examples
+
+Minimum change is to simply adjust the decorator
+
+```python
+# Old
+# def register_services(hass: HomeAssistant) -> None:
+#   @verify_domain_control(hass, DOMAIN)
+#   async def do_action(hass: HomeAssistant, call: ServiceCall) -> None:
+#     ...
+#   hass.services.async_register(...)
+
+# New
+def register_services(hass: HomeAssistant) -> None:
+  @verify_domain_entity_control(DOMAIN)
+  async def do_action(call: ServiceCall) -> None:
+    ...
+
+  hass.services.async_register(...)
+```
+
+To reduce code complexity, it is now recommended to move the service functions to be module-level functions
+
+```python
+# Old
+# def register_services(hass: HomeAssistant) -> None:
+#   @verify_domain_control(hass, DOMAIN)
+#   async def do_action(call: ServiceCall) -> None:
+#     entries = hass.config_entries.async_entries(DOMAIN)
+#     ...
+#   hass.services.async_register(...)
+
+# New
+@verify_domain_entity_control(DOMAIN)
+async def do_action(call: ServiceCall) -> None:
+  entries = call.hass.config_entries.async_entries(DOMAIN)
+  ...
+
+def register_services(hass: HomeAssistant) -> None:
+  hass.services.async_register(...)
+```
