libbi - Firmware Version 5.031

Released 27/07/2023 - Previous version 5.026

Bug Fixes

• Libbi will not report erroneous internal PV generation readings when there's less than 50W of actual PV being read by the MPPT inputs.

• The "linked devices info" screen 5/5, on the master device, will now show the correct aggregate myenergi devices total allotted powers including any libbi's charging or discharging.

• Improved reliability of schedules being sent to the libbi controller from the server.

Improvements

• Libbi controller reads and displays (information page 6 & 7) the ARM, DSP and BMS FW versions running on the inverter and each battery module.

• Calibration charge will trigger for newly added batteries, to older/existing libbi systems, without needing to do a factory reset.

• A new libbi system (with a battery having cycles less than 3) will trigger a calibration charge when the libbi controller local time reaches 1am for the first time after installation (or factory reset while battery is still at low cycles).

• If the battery is fully charged in the time between installation and before 1am next occurs, then the calibration charge will not trigger at 1am. This might have happened due to the battery charging from PV and meeting house loads in the duration since installation.

New Features

• None

Provided your libbi is connected to the internet the firmware will download automatically over the week following the firmware release.   Once downloaded, provided you are using the latest version of the myenergi app you will be prompted to complete the update in the app.

Alternatively you can complete the firmware installation from the libbi local controls - see this article for more details: Updating the firmware on your libbi
