Bug Fixes

  • G100 setting configuration in 3ph units : was only copied to CT2 and CT3 when the CT type was changed. This wasn’t the case when the actual setting was changed.
  • G100 protection only monitors active phases (so if a three phase zappi is only charging an EV using phase 1, low current measurements on phases 2 or 3 are ignored) (3.037)
  • Linked devices symbols ‘M’ and ‘~’ wasn’t displayed properly
  • Fixed priorities not updating on slave devices
  • Grid Limit in Wired Mode :  Fixed issue with grid current not resetting if power is being exported once limit is active
  • Fixed issue where other devices may be allotted power when zappi boosting even though importing from grid
  • Fixed issue with LED indicator colours resetting to zero/changing in upgrade from 2.176 to 3.033


  • Updated Swedish  and German translations
  • Improvement to speed of load control updates
  • Reset of radio module on lost transmit – fixes issue with zappi 2 comms lost (red zappi light on hub)
