serial

Description	Panel serial number extracted from the MQTT topic path (device/{serial}/...).
Type	String
Required	Yes

hardwareId

Description	Panel primary key in the device service DB, resolved via serial lookup (device.hardware.hardware_id).
Type	String
Required	Yes
Format	uuid

connectionPresent

Description	true if speaker 12V supply is present (ADC >= threshold, default 3704); false if disconnected or wiring fault.
Type	Boolean
Required	Yes

connectionFault

Description	true if speaker connection fault is detected (ADC < threshold); false if OK.
Type	Boolean
Required	Yes

bellFuseOk

Description	true if bell fuse integrity is confirmed (ADC >= fuse threshold, default 8849).
Type	Boolean
Required	Yes

bellFuseFault

Description	true if bell fuse fault is detected (blown fuse or abnormal current; ADC < fuse threshold).
Type	Boolean
Required	Yes
