ESP32_WiFi Take over LCD

[chris1howell]

The ESP32 module now has much more rich information than the OpenEVSE controller.

During Boot the ESP32 takes over writing to the LCD for several seconds to communicate WiFi SSID, Hostname and IP address. I propose keeping the ESP32 in control of LCD. The top line should stay the same with Status Service Level,Pilot current. The bottom line should cycle through important information relevant to the current state such as:
Power added 2.1kw
Internal Temp 48C
Elapsed time 1:23
Battery SOC 73% (if available)
Target SOC 85% (if available)
Time left 1:15 (if available)
Range 208 (if available)
Range Added 58 (if available)

Think this should be possible, I think this will need to be dependant on RAPI 5.0.0 to have the greater visibility of the menu state. @glynhudson and I have also talked about something similar for #54.

@glynhudson and I have also discussed connecting the LCD to the ESP and doing the full menu so that code can be removed from the OpenEVSE firmware (should save a load of code space)

If solar PV divert enabled:

Line0 "Eco Mode Enabled"
Line 1 "PV:xx.xkW EV:xxA"

[chris1howell]

To keep the interface consistent, we should not mess with Line 0 which displays important information State Service Level and Current. Divert is not just for PV, it can being used for any generation source, surplus or excess capacity. We really should move away from calling it Solar, beacuse it can be used in so many ways. I would suggest using line 1 only and use the same units and changing the message every xx seconds. Something like this. Line 1 "Divert xxxx.x Kw" Line 1 "Output xxxx.x Kw"
