🔄 HVAC Pause Blueprint – Changelog v1.7.1 → v2.0.0

This changelog explains the key improvements and structural changes introduced in version 2.0.0 of the HVAC Pause blueprint compared to version 1.7.1.

---

✅ Major Improvements in v2.0.0

1. Manual State Snapshot (No More scene.create)

• v1.7.1 used scene.create to store HVAC state.
• v2.0.0 saves state manually via Jinja variables:
  • hvac_mode (via states())
  • temperature
  • target_temp_low, target_temp_high
  • preset_mode, fan_mode, swing_mode
• 🔄 Enables full state restoration on devices that don’t support scene.create well (e.g. Samsung SmartThings).

---

2. Conditional Restore Logic

• Only updates a parameter if it differs from the current state.
• Prevents redundant commands and avoids unnecessary device toggling.

---

3. Reliable State Change Confirmation

• Each climate.set_* action is followed by a wait_for_trigger to ensure the change is reflected in the entity’s state.
• Example: after setting preset_mode, waits for the preset_mode attribute to update.

---

4. Null-safe Compatibility

• All parameters are checked with is number or is string before setting.
• Prevents errors like:

  expected float for dictionary value @ data['target_temp_low']
  

---

5. Wait-for-Resumed HVAC State

• After resuming HVAC via climate.set_hvac_mode, the automation waits until the climate entity’s state is no longer off before proceeding.

---

🛠 Best Use Cases

• SmartThings devices (Samsung WindFree ACs)
• MQTT or custom climate platforms
• Any system where full state restoration is required and scene.create is insufficient
