2.14.10 (2021-07-22)

  • PV surplus: if you don’t have a home battery, or the cloud override is turned off, the initial current is set 1 A higher than the minimum current, so that this hysteresis does not initially cause charge on-off due to light cloud cover.
  • Charge boost: If a home battery is present, it can be used for faster charging until it reaches a minimum charge level (10, 20, … 50%).
  • SMA Energy Meter reverted to code of 23.05., because the code was more stable (thanks, Ernst)
  • fixed several bugs and crashes
  • go-e now has a decimal place in the phase current overview

2.14.9 (2021-06-25)

  • Wallbox Heidelberg Energy Control” via the “wbec” project by steff393: https://github.com/steff393/wbec – super!
  • Inverter SOLARWATT
  • Inverter Kostal Piko (the old ones, Bj until 2018).
  • If you had set a “shutdown before 100% SoC” and the charge reference was way above 16A, but the car couldn’t charge that much because of a wallbox shutdown, then it shut down “unmotivated”. Now the reference value is the minimum of the set point and 16A. Thanks Klaus for the report
  • a negative reserve was also included when “PV assisted charging” was not activated. Thanks Klaus again
  • SimpleEVSE/SmartWB: A non-integer current is now supported – this should lead to much better readjustment in PV control. Thanks Tomasz, Frank and Matthias.
  • Keba: Fixed a bug that caused the app to hang occasionally (thanks Oliver).
  • SimpleEVSE/SmartWB: Support for histories in the EVSE software for accounting.
  • Made sure that by some stupid coincidence (kettle turned off, causing grid export to briefly go above 1.4kW by discharging home battery, and charging started “just like that”, and stayed on for a while due to cloud regulation) grid export cannot be higher than PV power.
  • Charge amounts extended to one decimal place, and the return from the charge amount calculator is now added to the existing charge amount.
  • UI improvement: moved car and wallbox selection from menu to action bar.
  • UI improvement: action title column made narrower.
  • UI improvement: fixed crash in horizontal layout for activities with multiple pages of information

2.14.8 (2021-06-04)

  • Crash when no car was in the car database (oops – the automatic creation of a car didn’t work) – Thanks, Jürgen!
  • Crash in Keba account management when in tablet mode – thanks, Heinz!
  • WebDAV setup now works correctly (thanks to many, but especially Karl-Heinz and David)
  • … and many small things … Trying with the new go-e hardware version 3, …

2.14.5 (2021-05-28)

  • crash when the user had no car data (ups – the auto-creation of a default car failed) – thanks Jürgen!

2.14.4 (2021-05-27)

  • “Clear Chart”-menu item is now only visible if a chart might be present (i.e. in PV surplus mode)
  • Added current power and energy as well as home battery state (if available) as texts to chart
  • improved PV-supported (not PV surplus!) charging with home battery
  • changed number of phases when switching cars was not immediately updated in the controls

2.14.3 (2021-05-27)

  • Needed to change the strategy with the phase count as more and more customers have multiple cars with different number of phases to charge with. So now the car database’s phase count is used to calculate the number of phases (for example as starting value for PV surplus control) unless the car is charging and the wallbox does return the correct number.
  • Added “wallbe Pro” (phoenix with inverted word order)

2.14.2 (2021-05-26)

  • An error in the English resource caused the list of wallboxes not to be displayed
  • fixed problem with go-e: when “energy to charge” was set, PV mode was active and the app was in the forground, charging re-started after the charger auto-resets the charge amount to 0.
  • Fixed problems in the wallbox database with user or password data
  • … and some other smaller problems of inconsistencies

2.14.0a (2021-05-09)

  • Support for multiple wallboxes (no energy management!)
  • go-eCharger MQTT configuration displayed in go-e extras
  • internal: separated databases
  • internal: dropbox migrated to short-lived token
  • database backup to dropbox
  • accounting CSV export to dropbox
  • several small bugfixes, UI enhancement
  • Keba: Account management, fixed some record inconsistencies of the charging records of the wallbox
  • 0b: some small bugfixes
  • 0c: sometimes the cloud backup power did not stop

2.12.0 (2021-04-12+15) not released

  • SMA Inverter (per Modbus/TCP)
  • E3DC easy connect Wallbox
  • Home Battery Power values in chart (if present)
  • User management (assign user name to RFID, or for (later) assignment to a charge item even without RFID)

2.11.0j+k (2021-04-12+13)

  • Cloud bridging sometimes did not switch off (thanks Karl-Heinz)
  • improved the PV surplus curve, as previously too much data, and sometimes not in the right order, at least here at my place, caused the algorithm to overreact.
