@tlrider, did you somehow resolve the problem?
i am currently using the SUN2000-8KTL-M1 firmware
V100R001C00SPC145 and a SDongleA with firmware V100R001C00SPC128. My PI 3b running Openhab 3.3 is connected to the same switch as the Dongle.
2022-06-29 23:34:09.498 [ERROR] [rt.modbus.internal.ModbusManagerImpl] - Last try 3 failed when executing request (ModbusReadRequestBlueprint [slaveId=1, functionCode=READ_MULTIPLE_REGISTERS, start=30073, length=10, maxTries=3]). Aborting. Error was I/O error, so resetting the connection. Error details: net.wimpi.modbus.ModbusIOException I/O exception: EOFException null [operation ID 8af19212-950a-4e53-8caa-8281c5364278]
my thing config looks like:
Bridge modbus:tcp:localhostTCP [ host=“192.168.1.104”, port=502, id=1, timeBetweenTransactionsMillis=1200, rtuEncoded=false, connectMaxTries=1, reconnectAfterMillis=0, timeBetweenReconnectMillis=0, connectTimeoutMillis=10000, enableDiscovery=false ]{

… and all other lines out of the config in the opening thread.
thanks for any reply.
