[goecharger] Added maxCurrTemp, tma1, tma2 and powerAll
Browse files Browse the repository at this point in the history 
Added changes
- replacing usage of tmp to tma1 and tma2
- new field powerAll for combined power of 3 phases
- new field maxCurrTemp to use the non-EEPROM value for max. current (amx)
- maxCurrent is still available (amp)

Changes 13.06.21:
Temperature is not supported any more, GO-E added two temperatures tma1 and tma2.

Added channel "Power over all" showing the combinde power of all three phases


## Setting charge current of Go-eCharger based on photovoltaik output

You can easily define rules to charge with PV power alone.

Item availablePVCurrent received update
then
logInfo("Amps available: ", receivedCommand.state)
MaxAmpere.sendCommand(receivedCommand.state)
MaxCurrTemp.sendCommand(receivedCommand.state)
end
```
You can also define more advanced rules if you have multiple cars that charge with a different amount of phases.
For example if your car charges on one phase only, you can set maxAmps to output of PV power, if your car charges on two phases you can set maxAmps to `pv output / 2`, and for 3 phases `pv output / 3`.
In general the calculation would be ´maxAmps = pvOutput / phases`.

Changes 06.21 (chilobo):
Since V3 of the GO-E-Charger Temperature is not supported any more, GO-E added two temperatures tma1 and tma2.
Added channel "Power over all" showing the combined power of all three phases
Added channel "Maximum current temporary": This changes the current. But this value is not written to the EEPROM.

Beware: Because of changes in V3 this binding is working for V1 and V2, but not for V3.
