v2.2.1 Release: Smart meter EAN & address resolution

Functional changes

• Added support for smart meter lookup using EAN (Electricity and Gas) codes
• Introduced new Smart Meter EAN-based lookup endpoints

Electricity EAN lookup

POST /api/v2/addresses/{address_uuid}/smart-meters/electricity/ean

• Finds the smart meter associated with a given electricity EAN at an address
• Request body:

{
  "ean": "871687940007565340"
}

Gas EAN lookup

POST /api/v2/addresses/{address_uuid}/smart-meters/gas/ean

• Finds the smart meter associated with a given gas EAN at an address
• Request body:

{
  "ean": "871687940007565340"
}

Purpose

Enables address-level resolution of smart meters using standardised EAN identifiers for electricity and gas connections.

This improves:

• Smart meter discovery and onboarding using external EAN identifiers
• Consistent mapping between addresses and metering infrastructure
• Support for integration flows where only EAN codes are available

Additional notes

• EAN format follows an 18-digit structure (8710xxxxxxxxxxxxxx)
• Electricity and gas EANs represent separate meter points within the same address context
