Released 07/11/2024 - Previous version 5.551
Please Note
This firmware release only applies to the zappi v2 with built-in Ethernet, Wi-Fi and "vHub". These zappis have a serial number starting with a "2" or higher.
It does not apply to previous versions of zappi without the built-in Wi-Fi/Ethernet.
New Features
3-Phase zappi installed on a single-phase supply only can now use :
- CT1 as a 1ph bidirectional load
- CT2 as a 1ph unidirectional load such as Storage (Heater)/Generation
- CT3 as a 1ph bidirectional load
Note that CT2 can only be set to 'None', 'Generation Only', 'Storage Only' or 'Heat Pump'.
CT2 power readings are calculated from assumed PF = 1.0 and can thus only be unidirectional.
CT3 power readings are based on dynamic metering IC channel (CT1/3) swapping. CT3 readings are taken from the metering IC by swapping the CT1 current channel dynamically.
Improvements
- Status Compactor, significantly reduces the volume of data exchange to the cloud.
- Improved Commercial Screen for 'Waiting for Surplus'. Waiting for surplus screen added for commercial mode.
Bug Fixes
- Not stopping a charge in ECO mode when the power limit is exceeded
- Master Lost - Zappi was periodically attempting to re-start a charge. Master Lost trigger timeout behaviour improved to prevent restarting a charge while the master device is considered lost.
- Drain libbi not working on non-ph1 phase. Fixed bug where libbi would not discharge to myenergi devices on a different phase when libbi was not on phase 1.
Additionally, the system has undergone several minor code enhancements and bug fixes to improve overall functionality and performance.
Important Notice
When updating to V5 firmware it is important that all zappis and eddis are also updated to V5 so that they can continue to work together.
