zappi 2 - Firmware Version 2.161Improvements

  • Updated Translations:
      • Dutch, French
      • “Coms” is now spelt “Comms”
  • Pilot Debug: Readings page 5. Now records real time readings
  • ECO+ mode: start/stop delay minimum value changed from 5 to 10s to prevent cycling
  • ECO+ mode: start/stop counter cannot start before the RCD board has finished to check for welded contacts. Prevent cycling at start of charge
  • Control Pilot readings: sampling logic improved to eliminate spurious Pilot Error! Trip

Bug Fixes

  • Inconsistency between Zappi true status and main screen display
  • PIN Lock : Zappi could lock itself from a Control Pilot x1 to x2 transition (B1 to B2 or C1 to C2). This fixes the problem in ECO+ where the PIN had to be re-entered every time the zappi tried to restart charging
  • Default Charge Mode : always started in ‘FAST’ on reboot (since V2.152)
  • Control loop caused PWM to be turned OFF while “RCD Checking…” leading to “Pilot Errors” and potential “RCD Tripped!”
  • Improved the way that surplus generation is shared between myenergi devices in ECO/ECO+ modes when Boosting
  • Corrected interaction between Smart Boost and Timed Boost – Timed Boost continued past end of the timed boost period if Smart Boost was also set.

Known Issues

The following known issues remain to be fixed:

– 3 phase zappi, built in CT’s not interpreted correctly in the app, resulting in a third of the power being reported
– Tesla Model 3 – does not correctly work in ECO+. This will required a firmware update from Tesla
