Root cause: The delete slave logic only: 1. Removed slave from options[CONF_SLAVES] 2. Reloaded the config entry But it didn't remove the device registry entry for that slave, leaving an orphaned device with identifier "{entry_id}_slave_{slave_id}". Solution: In options_flow.py async_step_select_slave(): 1. Import device_registry helper 2. Before reloading, look up the device by its identifier 3. Remove the device from device registry using async_remove_device() This ensures: - Clean removal of slave devices - No orphaned devices in the overview - Proper device lifecycle management --- custom_components/protocol_wizard/options_flow.py | 12 +++++++++++- 1 file changed, 11 insertions(+), 1 deletion(-) diff --git a/custom_components/protocol_wizard/options_flow.py b/custom_components/protocol_wizard/options_flow.py index 66f0ff7..d39856a 100644 --- a/custom_components/protocol_wizard/options_flow.py +++ b/custom_components/protocol_wizard/options_flow.py @@ -16,7 +16,7 @@ delete_template, ) from homeassistant import config_entries -from homeassistant.helpers import selector +from homeassistant.helpers import selector, device_registry as dr #import asyncio from .const import ( DOMAIN, @@ -162,6 +162,16 @@ async def async_step_select_slave(self, user_input=None): slaves = list(self._config_entry.options.get(CONF_SLAVES, [])) if idx < len(slaves): deleted = slaves.pop(idx) + deleted_slave_id = deleted.get('slave_id') + + # Clean up device registry entry for this slave + device_registry = dr.async_get(self.hass) + coordinator_key = f"{self._config_entry.entry_id}_slave_{deleted_slave_id}" + device = device_registry.async_get_device(identifiers={(DOMAIN, coordinator_key)}) + if device: + device_registry.async_remove_device(device.id) + _LOGGER.info("Removed device for slave %d from device registry", deleted_slave_id) + options = dict(self._config_entry.options) options[CONF_SLAVES] = slaves self.hass.config_entries.async_update_entry(self._config_entry, options=options)
