Using LAN data logger #20

Closed alekslyse closed 5 years ago

This is a bit strange problem - I have a set of WIFI stick and LAN stick (looks the same) and wanted to use the LAN sticks for security reasons as it seem like its not possible to turn off the AP on the WIFI sticks.

After some restarts I managed to get one MQTT output from the inverter, but most of the times it fails with this - seem like its possible to get it working, just something that doesnt make sense:

Just to show what happens when it works - if I reboot the script enough times this happens (with data in the mqtt log)

The simple reason is that the LAN interface uses protocol V5 which is not yet supported. I have little info from Omnik & Solarman about this new protocol. So it is still under development. I will get a LAN interface later this year. Then I will be able to debug & trace the new packet format.

Anything I can do for you to help you make it work?

XtheOne commented 5 years ago

Yes, If you can let your logger sent it's data to my test system I could work out the packet layout.

Please let me know the host and ip
