no "Query Inverters" flow

Going through the Readme it says to set the serial port in the "Query Inverters" flow but there is none.
I grep'ed the 6 flows and found ttyUSB0 in wvc-inverter-com flow.

I also got an error when entering my 4 digit inverter ID but it still accepted it and shows the output.

In the Raspberry Pi Interface flow I have not found what node red nodes to install to satisfy the String and Clear node types.

The String and Clear issue is cleared up with either installing node-red-contrib-string
I also ran sudo npm install -g npm@latest since contrib-objectid complained.

I also figured out the "invalid Input" warning on the inverter ID field after entering a valid number is because the init puts text in the field and the validation is complaining.
