Release Notes

The following release notes apply to Veva III - E01 and W01 models.

5.3.21 (February 3, 2026)¶

• FIX: Defensive fix implemented to prevent a rare occurrence where the vibration data appears to switch axes, then back (e.g. data from Z and Y axes switches) This issue was usually triggered when the histogram file upload cycle timer expired.
• FIX: Defensive fix implemented to prevent the timezone offset of the alarm trigger time in an MQTT alert message from differing by one hour from the alarm trigger time in the waveform data file. This causes the alarm record to be duplicated in Inzwa Cloud.
• KNOWN ISSUE: When audio alert is enabled, the audio alert file may contain Lmax value that is lower than the trigger level. For example, Trig Level=80, but Lmax=73.97.

5.3.20 (December 23, 2025)¶

• FIX: When MQTT is disabled because of connection error, MQTT will be enabled when the cellular communication module is periodically reset during the "Modem Reset Cycle." Prior to this fix, MQTT was enabled only when the device was reset or power cycled.
• FIX: Fixes issue where device produces histogram data with zero values when the sensor is idled by running the 'sensor idle' command.

5.3.19 (December 12, 2025)¶

• FIX: In the event of the device losing contact with the accelerometer, the device will reset itself.
• KNOWN ISSUE: When the accelerometer is idled by running the 'sensor idle' command, the device generates vibration peak data with zero values.
