2026-07-05 22:40 Global Status Log Fix

Problem

In fire_check-only mode, the global status monitor still printed values like:

person:1 | temp:0.0°C | threshold value:70.0°C

Those fields belong to fire_leave/thermometry logic. When thermometry startup fails and fire_leave is disabled, these values are not active runtime measurements and should not be shown as real current data.

Change

• Added latest fire_check result state in main.go:
  • FireCheckHasResult
  • FireCheckLastNumber
• Updated the fire_check result branch to record the latest detected fire target count.
• Updated printGlobalDeviceStatus():
  • prints fire:<value> for fire_check target count;
  • prints fire:null before any fire_check result is received;
  • prints person:null, temp:null, and threshold value:null when fire_leave is disabled;
  • keeps person/temp/threshold only when fire_leave is active;
  • adds fire_candidate, fire_last_seen_age, and fire_leave_enabled.

Expected Logs

Before any fire_check inference result is received:

[1] DeviceUUID=xxx | fire:null | fire_candidate:false | fire_last_seen_age:null | fire_leave_enabled:false | person:null | temp:null | threshold value:null | cooling time:0s

After fire_check reports one fire target:

[1] DeviceUUID=xxx | fire:1 | fire_candidate:true | fire_last_seen_age:500ms | fire_leave_enabled:false | person:null | temp:null | threshold value:null | cooling time:0s

If fire_check has reported a result but no fire target is present:

[1] DeviceUUID=xxx | fire:0 | fire_candidate:false | fire_last_seen_age:null | fire_leave_enabled:false | person:null | temp:null | threshold value:null | cooling time:0s

Impact

• Does not change fire_check alarm upload/report logic.
• Does not change heartbeat JSON format.
• Does not change inference startup arguments.
• Only changes runtime state tracking and global monitor log output.
• fire_leave logs remain available when fire_leave and thermometry are active.
