jkbms remotesocket unable to connect

[pedro042]

Environment:

• python 3.11
• venv (same as HomeAssistant)
• mpp-solar build from source, latest commit on branch master (but other versions same issue)
• BMS connected with JK RS485 adapter to USR-N540 device (but actually doesn!t matter, because of the error appears before communication)

Am I doing something wrong?
Thanks.

[jblance]

need to use rs485 protocol with the command - the default protocol for jkbms is the ble protocol
try adding -P jk485 or -P jk232 (though these havent been fully tested yet)
