Line 1 is just the project name, nothing else.
Line 2 will display "Connecting" during start up and lines 3 and 4 will show WIFI and MQTT getting connected.
Line 2 also has a dot that slowly flashes, once every few seconds. This is when a heartbeat message is being sent to the inverter.
If a message is read from the inverter that fails the CRC checksum, line 3 will display "CRC-FAULT". This could be caused by a loose or bad RS485 wire or by unsupported features.
If no response is received to a heartbeat message, lines 3 and 4 show "RS485 ERROR". This could be caused by disconnected or revered RS485 wires.
During start-up, line 4 shows the Sofar2MQTT software version. Check that you have the latest version at [https://github.com/cmcgerty/Sofar2MQTT](https://github.com/cmcgerty/Sofar2MQTT}
In normal operation, line 2 shows "Online" which indicates that both WIFI and MQTT are still connected.
In normal operation, line 3 shows the inverter run state, Standby, Charging, Discharging etc.
In normal operation, line 4 shows the power in W in or out of the batteries when charging or discharging.
