Breaking Changes

⚠️ Breaking changes - Upgrade to 3.x or later coming from prior versions

Version 3.0.0 and later introduces a breaking change in how entities are identified.

⚠️ What this affects

• This affects any update from a version prior to 3.0.0 to any version 3.x or later.
• This change may affect existing dashboards, automations, and scripts.

---

What changed

• Entities now use town_id instead of region_id in their unique_id.
• This change allows multiple integration entries that share the same region_id but different towns.

---

✅ Recommended upgrade procedure

To avoid issues with duplicated or unavailable entities:

1. Uninstall the existing integration (v2.x).
2. Restart Home Assistant.
3. Install v3.0.0 and configure the integration again.

---

🚨 If you update directly

If you update without uninstalling first:

• Old entities will remain as Unavailable.
• New entities will be created (sometimes with a suffix like 2).
• You may need to manually remove old entities and update your automations, dashboards, or scripts to point to the new entities.

---

Additional notes

• This change affects all entity types, including sensors, diagnostic sensors, and alerts.
• Always backup your Home Assistant configuration before performing major upgrades.
