- What happens when the Open EVSE is power cycled? Will the current setting revert to the default?
OpenEVSE saves a current setting for L1 and a separate setting for L2 in flash memory. If your station is set to Auto the relay will cycle on boot and determine if the power is L1 or L2. The saved setting will be applied. - How easy is it to adjust the current from the app when a wireless network is not available? Is there much difference between adjusting L1 and L2 currents?
If OpenEVSE fails to connect to your home network, it will start up its own Setup portal SSID OpenEVSE_xxxx. Connect to this portal with any WiFi enabled device and configure away. Connection info is displayed on the screen each time the station boots. - Should I purchase the capacitive button to make on the road adjustment easier?
WiFi is much easier, the button is a bit cumbersome. - Can any capacitive button be used? (Sparkfun, Adafruit, Aliexpress, etc)?
The button must be momentary and ground on activation. If the button is active HIGH it will not work without adding a NPN transistor. The OpenEVSE button has the NPN transistor built in.

An EV trip that we would like to make regularly ends in a campground with TT-30 connectors. Open EVSE appears to be a small but flexible solution so that we can use the full 24 Amps (80% of 30 Amps) available, .
