-Changelog for ahoy-all-in-one compared to 0.6.9 of the main project
-
-- read SML/OBIS from UART (stream parser with min resources needed); Connections 9600,8,n,1, GND-GND, VCC-3V3, TX-TX, RX-RX
-- prepared to show chart of grid power and total solar ac power for current days daylight period (6 a.m. to 8 p.m.)
-- show current grid power
-- show max solar ac/dc power
-- improved radio retransmit (complete retransmit if nothing was received, but only when inverter ought to be active) for the hm series
-- shortcut radio traces a little bit
-
-DRAWBACKS:
-- MQTT Source is commented out (except 1 var which is used for other purpose as well)
-- only up to 2 Inverters are supported (was: 10)
-- RX/TX of UART0 is used for serial interface to IR sensor. Of course you cannot operate a display that uses RX/TX pins of UART0, simultaneously. And unplug serial connection bevor updating via USB (see also below)
-- Due to a non-matching licence model of the charting lib certain parts of visualization.html are commented out. See comments there.

-But: Currently there is enough heap available for stable operation on a ESP8266 plattform (WEMOS D1 R1). So adjust the number of inverters and enable MQTT to your needs and see if the AHOY-DTU is still stable in operation with your hw plattform.
-To update firmware via USB, unplug serial connection to IR sensor first. Surprisingly during normal operation it seems that one can use a fully connected USB cable (for power supply). But I'm not sure if this works for all hardware plattforms.
