Inverter unavailable - no data

[jan-fitl]

Hello,
please forgive me if it has been already discussed, but I was not able to find and answer.

I have Solax X3H gen4 with Pocket LAN+WIFI 3.0 connected via cable to switch - wifi is not in use.

When I add it to HA everything works fine, the way it should.

But every now and then, usually every 3-4 reboots of HA the connection to inverter stop and not pooling any data. So each reboot is rather a nightmare for me.

I have figure out 3 solutions how to get that back up and running, which so far always one of them resolved the problem

1 - unplug cable from pocket lan and plug back in - (if that did not work then option 2)
2 - same as 1, unplug cable plug back in AND remove inverter as a device from HA and configure again - (again this sometimes does not work either so ultimate solution which always worked 3)
3 - unplug cable plug back in, remove Solax Modbus extention, install it from HACS again and configure

Any chance anyone of you having the same issue and possibly have a solution to this?

Note: I also have a TP Link omada setup, and just disabling port on switch and enabling back does not help, I need to physically disconnect the cable - which is fine when I am home, but when away then I am in trouble.

Thanks a lot,
J

Just had the same happen to my system. So followed you advise and it started working again after option 1. However my inverter is plugged into a Ubiquiti 5 port switch. So didn’t need to physically unplug, just did a remote reboot of the switch.
I appreciate it doesn’t solve the real problem.

thanks

I can copy and paste: Just had the same happen to my system. So followed your advise and it started working again after option 1. However my inverter is connected via WIFI and managed by Ubiquiti. So didn’t need to physically unplug, just did a remote reconnect.
Thank you very much. Now it is working again!

good point about the reboot of switch, that could be the remote solution, I have not tried that, since physically disconnect cable is quicker with the way to basement and back then booting of the switch.

And interesting to know that you both had the issue on Ubiquti, where I run on Omada, so this is clearly not an issue. I am more incline to believe that the issue is on the dongle side rather then this HA extension, as multiple reboots of HA never fixed that.

Just to add a little more info I had turned debug on and got nothing until the switch had a reboot.Then it produced a log file.
I have Octopus Energy attached as a service and log warned about this.
