VALLHORN and MYGGSPRAY expose multiple sub-devices (motion + illuminance) with different IDs but the same relation_id. Using the raw device ID as the HA device identifier caused each sub-device to appear separately. Use relation_id as the HA device identifier so sibling sub-devices are grouped under one device. Falls back to id for standalone devices. Also resolves sub-device naming: when a sub-device has no custom_name, it inherits the name from a sibling that does, avoiding garbled IDs.

Summary
relation_id(shared across sibling sub-devices) as the HA device identifier so multi-function devices like VALLHORN and MYGGSPRAY appear as one device with multiple entities instead of two separate devicescustom_namenow inherit the name from a sibling, avoiding garbled device IDs in entity namesdevice_trigger.pyidentity check to useunique_idinstead of device info identifiers, preventing breakage for controllers withrelation_idFixes #7
Migration note
Changing the device identifier from
idtorelation_idmeans existing HA devices for multi-function sensors will be orphaned and new (correctly grouped) ones created on first restart after upgrade. Users may need to delete the orphaned devices in the HA device registry. This is a one-time issue. Standalone devices (withoutrelation_id) are unaffected.Test plan
