4 months ago Update. After further troubleshooting with Jumpy07 on this "github issue" https://github.com/Jumpy07/Solis---SolisCloud-and-Home-Assistant/issues/10 , I found that my Elfin EW11 RS485 to WIFI unit was not receiving or sending any data. By trial and error I eventuallt realised that it seems the GC-1201 and EW11 manufacturers uses a different BUS naming convention so I had to swap the RS485 wires around, A-B and B-A, before I got any data throughput on the Elfin. So far so good.
However, in HA, using the "SolaX Inverter Modbus" integration (solis option) I get no devices no entities when I configure it. I see data traffic on the Elfin, so communication is there but no device. Any suggestions for further troubleshooting would be gratefully recieved.
Describe the bug
I connected my home made Jumpy07 RS485 sniffer (https://github.com/Jumpy07/Solis---SolisCloud-and-Home-Assistant) between my Solis inverter and its datalogger today. I ran your HA Solax integration config, using MODBUS address 1 (a guess), Solis inverter, ELFIN/EW11 IP address and port. HA Solax said "success" and "initialising" but ended with no devices no entities. I emailed Solis support for the miodbus number (I could not find it on soliscloud or my inverter webpage). Meanwhile, I tried various modbus numbers and worked my way down the SOLAX integration inverter list starting at Growatt. No dice until I tried Modbus 1 and inverter SRNE. Success! HA SOLAX int now reports 1 device and 24 entities. So FYI, the Solis inverter config in the SOLAX integration does not seem to work, but using SRNE does! Do you have any thoughts on this?
