I tried helping a friend who works as an electrician to connect to some SMA inverters/Data manager but had no success and can’t figure out why
Below is a list of all inverters/devices connected, tried enabling modbus on the EDMM-10 and one of the Tripower x20 and tried connecting with both the GitHub - CJNE/ha-sunspec: Home Assistant customcomponent for SunSpec modbus devices (get no connection to host) and the SMA integration (get authentication error). I have no trouble accessing the devices via their respective webUI using username/passwd.
I have made sure to enable modbus on these two units and to leave the default port of 502 unaltered.
I’m on a fresh install (VM) HA 2023.5.4
