I’m trying to get my SolarEdge SE3000H / meter combination working with Modbus TCP and SunSpec. I’m on OH 2.5.5 with Modbus 2.5.7. I actually have it working, but I’m getting a lot of errors in the log I’d like to clear up.
I created a modbus TCP slave, which is Online. That auto discovered my modbus Inverter and Meter, and I have added corresponding items which are updating just fine. However, I’m getting this error every 20 seconds.
2020-08-12 01:38:19.371 [ERROR] [ing.ModbusSlaveConnectionFactoryImpl] - connect try 1/5 error: Connection refused (Connection refused). Connection TCPMasterConnection@3eb1a2c[socket=Socket[unconnected]]. Endpoint ModbusTCPSlaveEndpoint@2fbe5361[address=<removed>,port=1502]
Any ideas how I can debug this?
