Multiple inverters? about pysma

[MYeager1967]

I found a workaround for this using custom. However, I have a rolling error in my log:

Any idea how to correct?

Hi @MYeager1967, unfortunately the custom option that I proposed on HASS community forums is the only option today. Have not had time to modify this to allow multiple inverters yet.

I have no idea why you would get aiohttp.client_exceptions.ServerDisconnectedError - are you trying to log into this using your web browser at the same time? / is this over wired/wifi?

Please try the configuring SMA via the UI... multiple inverters should now be supported - see https://www.home-assistant.io/blog/2021/05/05/release-20215/#breaking-changes
