Logger Serial Number does not match (Deye SUN-M80G3-EU-Q0)

[BasGo]

Describe the bug
Last week I got my PV with a Deye SUN-M80-G3 and tried to get all relevant ModBus values to MQTT. In the config I entered the serial number of the inverter (2305xxxxxx) and also tried the serial of the device itself (3944xxxxxx). Both serial numbers don't work and I get an error code 6 ("Logger Serial Number does not match. Check your configuration file.").

Expected behavior
Expected that this type of inverter works (as posted by someone else in #41.

Hardware (please complete the following information):

• Inverter model: Deye SUN-M80G3-EU-Q0

Software (please complete the following information):

• Logger firmware version: V1.57
• deye-inverter-mqtt version: latest (also tried out with local debugging)
• config.env:

DEYE_LOGGER_IP_ADDRESS=192.168.1.248
DEYE_LOGGER_PORT=8899
DEYE_LOGGER_SERIAL_NUMBER=2305xxxxxx

MQTT_HOST=192.168.1.200
MQTT_PORT=1883
MQTT_USERNAME=xxxx
MQTT_PASSWORD=xxxx
MQTT_TOPIC_PREFIX=deye

hi @BasGo

What kind of logger do you have? LAN or wireless? It's been reported that Modbus/TCP does not work for LAN loggers.

[BasGo]

I use the built in logger which is accessible wireless. The inverter/logger uses a wireless connection to my home network and has a fixed IP address.

Seemed to be a random issue: after two days of unsuccessful testing, it worked like a charm this morning. Without changing anything. Thanks for your assistance.
