Battery The uCIFI battery object provides attributes to monitor battery level and activity. 3411 urn:oma:lwm2m:ext:3411:1.1 1.0 1.1 Multiple Optional Battery level R Single Mandatory Integer /100 Level of charge of the battery in % of total possible charge. Battery capacity R Single Optional Float Ah Nominal capacity of the battery in Ampere hour. Battery voltage R Single Optional Float V Level of charge of the battery in Volts. Type of battery RW Single Optional String Describes the type of battery (e.g. Li-Ion rechargeable). Low battery threshold RW Single Optional Integer /100 Threshold below which an event is generated by the device. Battery level too low R Single Optional Boolean Set to True if battery level is below or equal the low battery threshold. Set to False otherwise. Battery shutdown RW Single Optional Boolean Indicates that the device has shut down due to battery discharge. Can be reset by central application. Number of cycles R Single Optional Integer Number of times the battery has discharged and recharged. Supply loss R Single Optional Boolean Applies for battery devices that are also connected to mains supply. Set to True when mains power is lost. Set to False when mains power is back. Supply loss counter R Single Optional Integer Number of supply losses since last reset. Supply loss counter reset E Single Optional Reset the supply loss counter. Supply loss reason R Single Optional String Reason identified by the device why the device has lost mains supply (e.g. lightning if the device measured a high voltage, accident if the device identified a move with an accelerometer). Timestamp R Single Optional Time The timestamp of when the measurement was performed. Fractional Timestamp R Single Optional Float 0..1 s Fractional part of the timestamp when sub-second precision is used (e.g., 0.23 for 230 ms). Measurement Quality Indicator R Single Optional Integer 0..23 Measurement quality indicator reported by a smart sensor. 0: UNCHECKED No quality checks were done because they do not exist or can not be applied. 1: REJECTED WITH CERTAINTY The measured value is invalid. 2: REJECTED WITH PROBABILITY The measured value is likely invalid. 3: ACCEPTED BUT SUSPICIOUS The measured value is likely OK. 4: ACCEPTED The measured value is OK. 5-15: Reserved for future extensions. 16-23: Vendor specific measurement quality. Measurement Quality Level R Single Optional Integer 0..100 Measurement quality level reported by a smart sensor. Quality level 100 means that the measurement has fully passed quality check algorithms. Smaller quality levels mean that quality has decreased and the measurement has only partially passed quality check algorithms. The smaller the quality level, the more caution should be used by the application when using the measurement. When the quality level is 0 it means that the measurement should certainly be rejected.
