Connection from OH3 to KEBA P30x wall-box using Modbus.
While reading of read-only registers is working very well I’ve encountered problems with write-only registers.
Bridge poller w1 [ start=5004, length=2, type="holding" ] {
Thing data SetChargingCurrent [ writeStart="5004", writeValueType="uint16", writeType="holding" ]
}
I get the following warning and then an error:
2022-03-21 13:24:57.739 [WARN ] [rt.modbus.internal.ModbusManagerImpl] - Try 1 out of 3 failed when executing request (ModbusReadRequestBlueprint [slaveId=255, functionCode=READ_MULTIPLE_REGISTERS, start=5004, length=2, maxTries=3]). Will try again soon. Error was I/O error, so resetting the connection. Error details: net.wimpi.modbus.ModbusIOException I/O exception: SocketTimeoutException Read timed out [operation ID 4dd62de0-0c74-4c5e-9013-22beb1772570]
What is wrong?
