JuicePedestal Unattended Payment Terminal (UPT) with OTA update through the embedded CAT-1 LTE modem.

New Features

A JuiceBox with LTE is now compatible with the UPT where these used to be mutually exclusive options.

New web interface command to manually delete utility 15 minute interval records. This is a debug/housekeeping feature.

Utility interval data for which there is no activity are no longer transmitted to the cloud. This is an optimization that reduces the amount of data sent to the cloud.

Resolved Issues

After an OTA through LTE or through the UPT, the WiFi credentials stored in non-volatile memory would occasionally be lost after the OTA. This issue has been resolved.

JuiceBoxes with LTE and RFID could lose a packet an hour because of a clash with an RFID housekeeping task. This issue has been resolved.

For LTE, the JuiceBox now performs an additional check whether a complete directory server response is received before accepting that response. If the response is incomplete, the directory server request is retried.

A JuiceBox that has lost connectivity has a watchdog timer to reboot after 30 minutes to try to re-establish connectivity. The reboot is delayed for an additional 30 minutes if the plug is connected to an EV.

Known Issues

Power measurements across two phases (for example, on Isolated Terra power grids) are not reported correctly.

Known Limitations

Wi-Fi configuration through Bluetooth not yet supported in firmware or mobile app. Bluetooth device setup will be supported in a future release.

European-style over-current protection is not enabled on JuiceBoxes sold in North America. Over-current protection is not required by US/North American standards.
