* Added wifi-debugging: if compiled in, you can debug SmartEVSE device by telnetting to it over your wifi connection
* Small code optimisations, fixed some small bugs
* Added EXPERIMENTAL use of Contactor 2 (C2);
-one can add a second contactor (C2) that switches off 2 of the 3 phases of a three-phase Mains installation; this can be usefull if one wants to charge of off
Solar; EV's have a minimal charge current of 6A, so switching off 2 phases allows you to charge with a current of 6-18A, while 3 phases have a minimum current
of 3x6A=18A. This way you can still charge solar-only on smaller solar installations.
-one should wire C2 according to this schema:

This way the (dangerous) situation is avoided that some Phases are switched ON, and Neutral is switched OFF.

-by default C2 is switched OFF ("Not present"); if you want to keep on charging on 3 phases after installing C2, you should change the setting Enable C2 in the Setup Menu.

-this functionality is EXPERIMENTAL; in Normal and Smart mode there are not much problems to be expected, but in Solar mode strange Start/Stop scenario's might
occur: we suspect a bug in the original AND our firmware that might make solar charging on 3 phases do strange Start/Stop things; this suspected bug can be
avoided by using 1 phase charging on solar. Also behaviour with Load Balancing with multiple Nodes is untested.
As always, YOU ARE EXPERIMENTING AT YOUR OWN RISK!

-LoadBalancing is allowed; especially the subpanel function (limit EVMeter to MaxCircuit) is well tested, but NOT the use of multiple EVSE's (Nodes)!!

-Currently Enable C2 will turn the contactor OFF (disabled) or ON (enabled) in any mode (Normal, Smart or Solar), regardless if LoadBalancing is on or off.
So you have to determine MANUALLY which contactor C2 behaviour you want. In the future the firmware [sh|c]ould become smarter in this, switching C2 on and off
(semi-) automatically.
