Can't connect to inverter SE6K

[artur5236]

Hello,
I have turn on modbus tcp 1502 port on my inverter SE6K.
I have connected inverter via ethernet.
Plugin can't connect to inverter:

I also have HomeAssistant with plugin modbus tcp and this same inverter working fine.

This issue was resolved.

Hi @artur5236,
Can you explain what you did to get the error resolved?

[artur5236]

Disabling plugin (modbus tcp) in Home Assistant helped. I suppose the inverter can be connected to one host at a time.
But domoticz plugin still doesn't works, I received error: received fatal signal 11 (Segmentation fault)
#28 (reply in thread)

[addiejanssen]

Yes, that makes sense. It is a bit unpredictable when the inverter allows multiple connections and when it doesn't. I have 2 domoticz virtual machines running and both can retrieve information from the inverter. But when I try to run 2 processes on the same computer, then 1 will for sure will fail.
