Additional context

thank you for this contribution to HA, if it can get to work, it will really help me out and a lot of people that have the same issue with trying to get away from the official GW data logging.

I'm using HA on a Oracle VirtualBox virtual machine, I'm doing this to test out HA before purchasing a dedicated device. I have installed a new instant of HA to try to test how i can connect to my Growatt inverter with proper real-time stable updating eg 1 sec intervals to actively switch switches on and off.
I'm having problems with this ne instance that when loading it keeps giving a supervisor failed to load error, but i don't think it is related
